D
Solve for x
Step-by-step explanation:
the upper (smaller) triangle and the complete triangle are similar.
that means the angles in both triangles are the same. and the lengths of all corresponding pairs of sides correlate with the same scaling factor.
therefore,
(8x - 10) / (8x - 10 + 18) = 25 / (25 + 15)
(8x - 10) / (8x + 8) = 25 / 40 = 5/8
8(8x - 10) = 5(8x + 8)
64x - 80 = 40x + 40
24x = 120
x = 5
help Mary ann and carlos are each saving for new scooters. Their savings are shown. Let x represent the number of hours each person works y represent the total earnings in dollars
after how many hours of work will mary ann and carlos have saved the same amount?
Answer:
4 hoursStep-by-step explanation:
Use a couple of ordered pairs on the graph and get the equation of the line:
(0, 2), (1, 10)The y-intercept is 2 and the slope is 10 - 2 = 8
The line is
y = 8x + 2Solve the system of equations by substitution to find the intersection
y = 6x + 10y = 8x + 26x + 10 = 8x + 28x - 6x = 10 - 22x = 8x = 4They will work 4 hours to get same amount of saving
Answer:
4 hours
Step-by-step explanation:
First, create a linear equation for Carlos using the graph.
Two points on the line: (0, 2) and (1, 10)
[tex]\implies \sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{10-2}{1-0}=8[/tex]
Use the point-slope equation with the found slope and one of the points:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-2=8(x-0)[/tex]
[tex]\implies y=8x+2[/tex]
Now equate the equations for Mary Ann and Carlos, and solve for x:
[tex]\implies 6x+10=8x+2[/tex]
[tex]\implies 8=2x[/tex]
[tex]\implies x=4[/tex]
Therefore, Mary Ann and Carlos have saved the same amount after 4 hours work.

What is the length of side AB of parallelogram ABCD?
units
4g - 8
B
q+4
Answer:
8 units
Step-by-step explanation:
» Concepts
Parallelogram Side Theorem states that the opposite sides of a parallelogram are congruent, meaning they have the same length.
» Application
In this case, we're asked to apply the theorem to find the value of q and then find the length of AB. Thus, we have to set up the equation 4q - 8 = q + 4.
» Solving
Step 1: Subtract q from both sides.
[tex]4q-8-q=q+4-q[/tex] [tex]3q-8=4[/tex]Step 2: Add 8 to both sides.
[tex]3q-8+8=4+8[/tex] [tex]3q=12[/tex]Step 3: Divide both sides by 3.
[tex]3q/3 = 12/3[/tex] [tex]q=4[/tex]Step 4: Plug in the value of q for side AB.
[tex]4(4)-8[/tex] [tex]16-8[/tex] [tex]8[/tex]Therefore, the answer is 8 units.

The coordinates of parallelogram UVWZ are U(a, 0), W(c-a, b), and Z(c,0). Find the coordinates of V without using any new variables
A• (0, b)
B• (c, b)
C• (a, b)
D• (b, 0)
Answer: Choice A.
(0, b)
==================================================
Explanation:
Pick any random 3 numbers you want for a,b,c.
a = 1b = 2c = 3The points U, W and Z become
U = (a,0) = (1,0)W = (c-a, b) = (3-1, 2) = (2,2)Z = (c, 0) = (3, 0)Or in short,
U = (1,0)W = (2,2)Z = (3, 0)Plot each of those points on the same xy grid.
Next, using a different color, plot each of the answer choices.
A is at (0,b) = (0, 2)B is at (c,b) = (3,2)C is at (a,b) = (1,2)D is at (b,0) = (2,0)You should find that point A helps form a parallelogram, while the other answer choices don't lead to a parallelogram.

The diameter of a circle is 38 in. Find its area to the nearest whole number.
Answer:
1134
Step-by-step explanation:
Formula for diameter=2 x r
(π is 3.14)
Formula for area= π x r^2
So all you basically have to do is go backwords with the first one then plug the radius into the second one normally
38/2=19
Now just plug it into your second equation
π x 19^2=1134.11494795
And lastly round that to 1134, easy! :)

solve the system of equatioins 2x+3y=40 and -2x+2y=20
Answer:
x = 2 ; y = 12
Step-by-step explanation:
2x + 3y = 40
+ -2x +2y = 20
You solve for one of the variables by cancelling out one and making one the subject.
2x + 3y = 40.
+ -2x +2y = 20
5y = 60
5y/5 = 60/5
y = 12
Next, you solve for X by replacing the value of y in any of the equations.
2x + 3y = 40
2x + 3(12) = 40
2x + 36 = 40
2x = 40 - 36
2x = 4
2x/2 = 4/2
x = 2
To prove the equations are set, replace the values of X and Y in one of the equations.
2x + 3y = 40
2(2) + 3(12) = 40
4 + 36 = 40
40 = 40

is this a quadratic function 2x+13=13
Answer:
Step-by-step explanation:
Simplifying
2x + 13 = 0
Reorder the terms:
13 + 2x = 0
Solving
13 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 2x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 2x = 0 + -13
2x = 0 + -13
Combine like terms: 0 + -13 = -13
2x = -13
Divide each side by '2'.
x = -6.5
Simplifying
x = -6.5

The midpoint of AB = ([?],[])
=PLEASE HELP I WILL MARK BRAINLIEST
Explanation:
The x coordinates of points A and B are 2 and -2 respectively. Add them up and divide by 2 and we would get (A+B)/2 = (2+(-2))/2 = 0/2 = 0.
The x coordinate of the midpoint is 0.
The y coordinate of the midpoint follows the same idea, but we focus on the y coordinates of course. You should find the y coordinate of the midpoint is 0.
The midpoint is at (0,0) as the diagram shows.

On solving, we have
