3/2 = 5d - 1/2

solve for d

​

Answers

Answer:

D = 2/5 or 0.4

Step-by-step explanation:

3/2 = 5d - 1/2

move the terms

3/2 - 5d = -1/2

calculate the difference

-5d = -2

divide both sides by -5

2 = 2/5

Answer

3/2 = 5d - 1/2
+1/2 +1/2
2=5d
divide both sides by 5

D = 2/5

Answers

Answer:

Step-by-step explanation:

You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional.  So set up two ratios that are = to each other

On the left

long side small triange / long side large triangle = base small triangle / base large triangle

On the right

hypotenuse/longest leg = hypotenuse / longest leg.

Problem A

Set up the similar Proportion

5/40 = x/20                Cross Multiply

40x = 20*5

40x = 100                   Divide by 40

x = 100/40

x = 2.5

Problem B

Again set up the similar triangle proportion

15/10 = x/2                  Multiply by 2

15*2/10 = x              

3 = x

for the first one x=2.5
for the second one x=3
