A triangle has a total degrees of 180, so you add 55 and 53 to get 108
then you subtract that from 180 to get 72. 72 is your answer
Answer:
72 degrees
Step-by-step explanation:
First of all, you should know that each triangle equals to 180 degrees. So just add 55 + 53 which equals 108. Then you just subtract 108 from 180 (180-108) which equals to 72 degrees.
Therefore, the third missing angle measure is 72 degrees.
Hope this helps! :)

Substitution
y=7x+3
Answer: x= 1/7 y + -3/7
Step-by-step explanation:
y=7x+3
Step 1: Flip the equation.
7x+3=y
Step 2: Add -3 to both sides.
7x+3+(−3)=y+(−3)
7x=y−3
Step 3: Divide both sides by 7.

Answer:
y = -5x + 7Step-by-step explanation:
Find the slope:
m = (- 8 - 2) / (3 - 1) = -10 / 2 = -5Use the point (1, 2) and find the equation:
y - 2 = -5(x - 1)y = -5x + 5 + 2y = -5x + 7Mrs. Thomas has two rolls of garden edging that are each 96 inches long.
She wants to make two new flower beds in her back yard. Each flower bed
will be bordered by one roll of the edging. One flower bed will be in the
shape of a quadrilateral. The other will be in the shape of a triangle.
Please answer all parts. I will give brainliest for correct answer!
Answer:
A) The total length of each edging in her scale drawing would be 19.2 centimeters.
B) Square or rectangle
C) angle α= 53.13 degrees
angle β= 36.87 degrees
height= 32 inches
base= 24 inches
hypotenuse 40 inches.
Step-by-step explanation:
Part A:
If the roll edging is 96 inches long and the scale chosen is
5inches = 1 cm
96inches /5= 19.2cm
The total length of each edging in her scale drawing would be 19.2 centimeters.
Part B:
The quadrilaterals such rectangle square right trapezoid have a pair of 90 degrees angles.
If we choose a square shape then all sides must be equal. And we have a length of 19.2 centimeters.
Dividing 19.2 by 4 gives 4.8 cm for each side.
Figure A shows a square and has 4 sides equal and 4 right angles.
If we choose a rectangle shape then 2 sides must be equal. We have a length of 19.2 centimeters.
Suppose the length is 2 times more than the width
which will give the dimensions as
2*2 x+ 2x= 6x ( length and width denoted by x)
Dividing 19.2 by 6 gives 3.2 cm for each width and 6.4 for the lengths.
Figure B shows a rectangle and has 2 sides equal and 4 right angles.
It depends on which quadrilateral you wish to choose.
Part C:
Using Pythagorus theorem if the base and altitude are given then the hypotenuse can be found out using the following formula.
c²= a² +b²
c²= 6.4² +4.8²
c²= 40.96+23.04= 64
c= √64 = 8
The third side must be equal to 8 centimeters.
Using the formula
Cos α= base / hypotenuse
Cos α=4.8/8
α= Cos (inverse) 4.8/8
α= Cos (inverse) 0.6
α= 53.13 degrees
So angle α= 53.13 degrees
All the angles in the triangle must be 180 degrees.
α + β + 90°= 180°
And angle β= 180-90-53.13= 36.869= 36.87 degrees
The actual dimensions of this triangle are
height= a= 6.4* 5= 32 inches
base= b= 4.8*5= 24 inches
hypotenuse= 8*5= 40 inches.
How many solutions are there to the equation below?
3x - 10(x+2) = 13 - 7x
O A. O
B. 1
O C. Infinitely many
Answer:
A) 0 (no solutions)
Step-by-step explanation:
Solve the equation:
3x - 10(x+2) = 13 - 7x
3x - 10x -20 = 13 - 7x
-7x - 20 = 13 - 7x
-20 = 13
Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.
Answer:
It would be 0
Step-by-step explanation:
because its -7x+20=13-7x which in the end would 20=13
Andrea ran 4 kilo over the weekend. How many meters did she run
Using a graphical method, solve the simultaneous equations x+y =4 and y=2x+1
Answer:
(1, 3)
Step-by-step explanation:
Given the expression
x+y = 4 ... 1
y = 2x+1 ....2
Substitute equation 2 into 1
x + (2x+1) = 4
3x + 1 = 4
3x = 4-1
x = 3/3
x = 1
Since y = 2x + 1
y = 2(1) + 1
y = 3
Hence the solution to the equation is (1,3). This means that the coordinate point on the graph where both lines intersect will be at (1, 3)

50 decreased by ??? is 40
options are
60% 80%
19% 40%
Answer:
19%
Step-by-step explanation:
40/50 = x/100
solve for x
x is equal to 20%
but out of the answer choices it's 19%.
Answer: 19%
Step-by-step explanation:
50, percentage decreased by 60% (percent) of its value = 20
50, percentage decreased by 80% (percent) of its value = 10
50, percentage decreased by 19% (percent) of its value = 40.5
50, percentage decreased by 40% (percent) of its value = 30
Hence, the answer is 19%

I would like an explanation how to do it too, IF you dont mind.
Answer:
Phoebe has £180, Andy has £60, and Polly has £30.
Step-by-step explanation:
Ok, to start of let's establish some variables! We'll give Phoebe the variable "p", Andy the variable "a", and Polly the variable "o". By giving each person a variable we can create an equation and solve for it!
So, what do we know?
Well we know the following information...
p + a + o = 270
(Phoebe + Andy + Polly = £270)
p = 3a
(Phoebe = 3 times more than Andy)
a = 2o
(Andy = 2 times more than Polly)
To be able to solve this equation we have to solve for just one variable first.The only one we can use is "o" for Polly!
3(2o) + 2o + o = 270
6o + 2o + o = 270 (Distribute 3 to get like terms)
9o = 270 (Combine like terms [6+2+1])
o = 30 (Divide by 9 on both sides to get "o" by itself)
Now that we have how much Polly has, we have to solve for Andy and Phoebe. (To do this we will input our value, 30, where our variable is "o")
Andy
a = 2(30) (Input term)
a = 60 (Multiply by 2 to get final answer)
(Since we now know what Andy has we can input 60 into our "a" variable to solve for Phoebe)
Phoebe
p = 3(60) (Input term)
p = 180 (Multiply by 3 to get final answer)
Now! Just to check we are going to input our variables into our original equation to be sure we have the right variables.
p + a + o = 270
180 + 60 + 30 = 270!!
Hope this Helps! :)

Which could be used to find the number n? “Four less than a number, n, is equal to fifteen.”
A, ,B C, Or D
Answer:
C (n - 15 = 4)
Step-by-step explanation:
This is the answer becuase it can be rewritten as:
n - 4 = 15 (by subtracting 4 from both sides and adding 15 to both sides);
this equation describes the "written" (verbal) equation.

5 divided by 2,165 equals?
answer:
1/433 (decimal: 0.002309)
step-by-step explanation:
5/2,165
= 1/433
to change 1/433 to decimal we'll divide the numerator by the denominator-
1÷433
=0.00230946882
so we're going to round to the ten-millionths place
5 or more raise the floor, 5 or less let it rest
4>5
so 0.002309
good luck :)

wriye each expression with fewer terms.Show your work or explain your reasoning 10x-2x 10x-3y+2x
Answer:
20x-3y
Step-by-step explanation:
combine the like terms
so first do 10x-2x=8x
then you're gonna add from the line the 10x and the 2x which is going to give you 20x
no finally you are left with one number with the y variable, that is 3y.
Therefore your answer is 20x-3y
