A length on a map is 7.5 inches. The scale is 1inch & 5 miles. What is the actual distance?
Answer: Actual distance = 37.5 miles
Step-by-step explanation:
Let x be the actual distance
Given information
Length on map = 7.5 inches
Scale = 1 inch : 5 miles
Set up proportion
[tex]\frac{7.5}{x} =\frac{1}{5}[/tex]
Cross multiply to convert out of fraction form
[tex]7.5*5=1*x[/tex]
[tex]\boxed{x=37.5}[/tex]

3y-4(5x-3y+y²) expand and simplify
Answer:
23x + 12y + -4xy^2
Step-by-step explanation:
So lets first expand
3y (-4 x(5x - 3y + y^2)
let's ignore 3y for now
Since 5x - 3y + y^2 can't be simplified, we move on to multiplying each number.
note: Capital X = Multiplying symbol
___________________________________
-4 X 5x, -4 X - 3y, -4 X y^2
= -20x + 12y + -4xy^2
now we bring back the 3x
3x - -20x + 12y + -4xy^2
so now we simplify, by finding like terms
= 23x + 12y + -4xy^2

it is not possible -4=0
S0 there is no solution in equation.
Answer:
No solutions
Step-by-step explanation:
Simplify the given equation:
[tex]7(x+2)=7x-10[/tex]
Distribute, multiply every term inside of the parenthesis by the term outside of it.
[tex]7(x+2)=7x-10[/tex]
[tex]7(x)+7(2)=7x-10[/tex]
Simplify,
[tex]7x+14=7x-10[/tex]
Inverse operations,
[tex]7x+14=7x-10[/tex]
[tex]7x+(-7x)+14=7x+(-7x)-10[/tex]
Simplify,
[tex]7x+(-7x)+14=7x+(-7x)-10[/tex]
[tex]7x-7x+14=7x-7x-10[/tex]
[tex]14=-10[/tex]
This equation simplifies down to an untrue equation, therefore, there are no solutions to this equation.

Geometry, please answer question ASAP
Answer:
x = 60
Step-by-step explanation:
The sum of the interior angles of a quadrilateral is 360 degrees.
So if we sum up all the given angles, we would get this equation:
2x + x + 90 + 90 = 360
which simplifies to
3x + 180 = 360
subtract 180 from both sides
3x = 180
divide both sides by 3
x = 60
Answer:
Below!
Step-by-step explanation:
Since all angles in this shape add up to 360, I used this formula to find x
360 = 90 + 90 + x + 2x
360 = 180 + 3x
180 = 3x
Divide both sides by 3
60 = x
You can check to see if this works
90 + 90 + 60 + 120 = 360

You drive 132 miles in 3 hours. At
that speed, how many hours would it take you to drive 110 miles?
Answer and Step-by-step explanation:
To solve, we need to find how many miles are driven in an hour.
Divide 132 by 3.
132/3 = 44
Now, we need to find how many hours it would take to drive 110 miles.
[tex]\frac{44 miles}{1 hour} = \frac{110 miles}{? hours} \\\\[/tex]
Cross multiply.
[tex]44(?) = 110[/tex]
Divide by 44.
[tex]? hours = 2.5 hours[/tex]
So, it would take 2.5 hours to drive 110 miles.

Answer:
(- 3, 2 )
Step-by-step explanation:
Given the 2 equations
x + 3y = 3 → (1)
- 2x + 3y = 12 → (2)
Subtract (1 ) from (2) term by term to eliminate y
- 2x - x + (3y - 3y) = 12 - 3
- 3x = 9 ( divide both sides by - 3 )
x = - 3
Substitute x = - 3 into either of the 2 equations and solve for y
Substituting into (1)
- 3 + 3y = 3 ( add 3 to both sides )
3y = 6 ( divide both sides by 3 )
y = 2
solution is (- 3, 2 )

What is the value of x?
Answer:
62 is the answer to your question
one quick way to know the answer is to know that the two opposite interior angles has to add up to the outer external angle, so x + 38 = 100
Answer:
B. 62°
Step-by-step explanation:
First, solve the unknown interior angle. Interior angles and exterior angles add up to 180°.
? + 100 = 180
? = 80
The sum of the angles of a triangle is 180°. Form and solve the following equation.
x + 80 + 38 = 180
x + 118 = 180
x = 62

2√8 x √20
Which of these is equivalent to this expression?
A. 2√28
B. 5
C. 8√10
D. 32√10
Answer:
8 sqrt(10)
Step-by-step explanation:
2 sqrt(8) * sqrt(20)
We know sqrt(a) * sqrt(b) = sqrt(ab)
2 sqrt(8) * sqrt(20)
2 sqrt(160)
2 sqrt(16*10)
2 sqrt(16) sqrt(10)
2 *4 sqrt(10)
8 sqrt(10)
Answer:
First, we can write 2√8 as 2 x √8. This will make the next calculations easier.
So the problem becomes 2 x √8 x √20.
We can group together √8 and √20, to get √160.
And we have: 2√160.
However, this can be simplified further, as 16x10 = 160, and so we obtain the final answer of 8√10.
C is correct.

Problem: 4x - (x - 4) = - 20
I desperately need a good grade because this is my first grade.
Correct answer is brainiest!
Answer:
x = -8
Step-by-step explanation:
4x - (x - 4) = - 20
Distribute the minus sign
4x - x +4 = -20
Combine like terms
3x+4 = -20
Subtract 4 from each side
3x+4-4 = -20-4
3x = -24
Divide by 3
3x/3 = -24/3
x = -8
Answer:
x = -8
Step-by-step explanation:
4x - (x - 4) = -20
~Simplify
4x - x + 4
~Subtract 4 to both sides
3x = -24
~Divide 3 to both sides
x = -8

PLEASE HELP!!
Answer:
<a = 30
<b = 60
<c = 115
Step-by-step explanation:
<a = 30 since they are vertical angles and vertical angles are equal
<a + < b + 90 = 180 since they make a triangle
30 + <b +90 = 180
120 + <b = 180
<b = 180-120
<b = 60
<c + 75 = 180 since they form a straight line
<c = 180-75
<c = 115
Answer:
a=30
b=60
c=105
Step-by-step explanation:
We know a=30 because 30 and a are the same
The middle forms a triangle and triangles are equal to 180
The box indicates that the angle is 90 degrees
180=a+b+90
180=30+90+b
b=60
Angle c is supplementary to 75 so it must equal 180
180=c+75
c=105

at old oak farm, there are chicken and horses. there are 120 legs and 48 heads altogether. how many horses and how many chickens are there?
Answer:
Step-by-step explanation:
We must use system of equations:
horses = h chickens = c
horses have 4 legs & chickens have 2 and there are 120 legs total so to set up the first part of the equation...
4h + 2c = 120
They both have only 1 head each and there are 48 heads total so to set up the second part of the equation...
h + c = 48
Now we combine the equations and solve:
4h + 2c = 120
h + c = 48
Now we solve...
4h + 2c = 120
h = 48 - c (subtract c on both sides to single out h)
--------------------
4(48 - c) + 2c = 120
192 - 4c + 2c = 120
-192 -192
----------------------------
-2c = -72 (divide both sides by -2)
c = 36
Now we go back and find the value of h...
h = 48 - c
h = 48 - 36
h = 12
So there are 36 chickens & 12 horses!

Answer:
240 ft^2
Step-by-step explanation:
The rectangular prism has 6 faces. Each two opposite faces have the same area. We need to find the areas of 3 faces that are not opposite faces, add them, and then multiply by two.
Top face:
7 ft by 6 ft
area = LW = 7 ft * 6 ft = 42 ft^2
Right face:
7 ft by 6 ft
area = LW = 7 ft * 6 ft = 42 ft^2
Front face:
6 ft by 6 ft
area = LW = 6 ft * 6 ft = 36 ft^2
Sum of areas of 3 faces:
42 ft^2 + 42 ft^2 + 36 ft^2 = 120 ft^2
Now we double the area to account for the 3 faces that are opposite each one of the three faces whose areas we calculated.
2 * 120 ft^2 = 240 ft^2
Answer: 240 ft^2

Answer:
56.55 units
Step-by-step explanation:
If we rotates this rectangle we will get a cylinder.
The base of this cylinder is a circle with a radius of 3 units (the high of the rectangle).
And the high of this cylinder is 2 units.
Volume of cylinder is given by the formula :
V= h.pi.r²
so V= 2×3.14×9
= 56.55 units
Lines EG and FH are parallel. a. Name all the angles congruent to angle ABE. 7.1 D G b. Wnte an equation that represents the relationship between angle FCD and angle HCD.
Answer a here (separate answers with a comma): *
Answer b here: *
Answer:
a. GBC, FCB, DCH
b. FCD+HCD=180
Step-by-step explanation:
A
by vertical angles ABE=GBCby corresponding angles ABE=FCBby alternate exterior angles ABE=DCHB
FCD and HCD form a straight line which is equal to 180The angles that are congruent to ABE are BCF, DCH, and CBG
Angles FCD and HCD lie on the same straight line. This means that the sum of both angles will sum up to 180degrees since the sum of angle of a straight line is 180degrees (supplementary). Hence the required equation will be:
<FCD + <HCD = 180
An angle is a point where two lines meet or intersect.
The angles that are congruent to ABE are BCF, DCH, and CBG
ABE = BCE (corresponding angle)
Since BCE = DCH (vertically opposite angles), hence:
ABE = DCH (vertically opposite angles)
Also, we can see that DCH = CBG (corresponding angles), hence:
ABE = CBG (corresponding angle)
b) From the given diagram, we can see that angles FCD and HCD lie on the same straight line. This means that the sum of both angles will sum up to 180degrees since the sum of angle of a straight line is 180degrees (supplementary). Hence the required equation will be:
<FCD + <HCD = 180
