<span><span>Corresponding angles are congruent (same measure)So in the figure above, the angle P=P',  Q=Q',  and R=R'.</span><span>Corresponding sides are all in the same proportionAbove, PQ is twice the length of P'Q'. Therefore, the other pairs of sides are also in that proportion. PR is twice P'R' and RQ is twice R'Q'.  
so the value of x :
x / 110 = 21.6 / 72
solve for x
x = 33</span></span>

25 = 4.5z + 12<br> What is the solution for z
diamong [38]

Answer:

2.89

Step-by-step explanation:

Note the equal sign, what you do to one side of the equation, you do to the other. To solve, do the opposite of PEMDAS. Isolate the variable, z.

First, subtract 12 from both sides:

25 = 4.5z + 12

25 (-12) = 4.5z + 12 (-12)

25 - 12 = 4.5z

13 = 4.5z

Isolate the variable, z. Divide 4.5 from both sides:

(13)/4.5 = (4.5z)/4.5

z = 13/4.5

z = ~2.89 (rounded).

2.89 is your answer.

Ken's fitness member ship cost $100 to join plus a $25 monthly fee. Ken also used a coupon to get 10% off the monthly fee. What
GREYUIT [131]

The equation that models the total cost is y = 100 + 22.5m

Step-by-step explanation:

Fitness member ship cost = $100

Monthly fee = $25

Discount = 10% on monthly fee

To calculate new monthly fee after discount,  

25 - (25*10%) --> 25 - 2.5 --> $22.5

Number of months = m

Fee in m months = 22.5*m = 22.5m

<u>Equation:</u>

(c) is constant which is the membership fee

(x) is the monthly fee $22.5

(m) is the number of months

(y) is the total cost

So,

y = mx + c

y = m(22.5) + 100

y = 100 + 22.5m

Therefore, the equation that models the total cost is y = 100 + 22.5m
