Answer
(13+4) + (4.63+7.4)
Step-by-step explanation:
Use the commutative property to put the decimals together. Use the associative property to group the decimals and numbers together as shown in the answer.
Answer:
Yes they are proportional because he is selling cars at the same rate
Step-by-step explanation:
<u>Given</u>:
Given that the triangle ABC is similar to triangle FGH.
We need to determine the value of x.
<u>Value of x:</u>
Since, the triangles are similar, then their sides are proportional.
Thus, we have;

Let us consider the proportion
to determine the value of x.
Substituting AB = 9 cm, GF = 13.5 cm, BC = 15 cm and GH = x, we get;

Cross multiplying, we get;



Thus, the value of x is 22.5 cm
Hence, Option F is the correct answer.
