Answer:
12.6
Step-by-step explanation:
The two left sides have lengths, so this allows you to establish the ratio of the lengths of the sides of the triangles,
left triangle : right triangle
ratio = 25 : 17.5
The bottom sides are also in the same ratio.
ratio = 18 : w
Write a proportion by setting the ratios equal and solve for w.
25/17.5 = 18/w
Cross multiply.
25w = 17.5 * 18
25w = 315
w = 12.6
Answer: 12.6
Answer: 2.5
Step-by-step explanation:
y = rx
substitute numbers in and solve for r
if
y = 10
x = 4
then
10 = r4
r = 10/4 = 2.5
this works for all the other numbers and always gives r = 2.5
Answer:
x=2.5
Step-by-step explanation:
5x<12 1. /5 on both sides
x= 2.5
<u>Answer:</u>
- $2,800 = Principle + Interest
<u>Step-by-step explanation:</u>
Using PRT/100, let's find the interest.
- => 2,000 x 8 x 5/100
- => 20 x 8 x 5
- => $800
<u>Conclusion: </u>
Therefore, the interest plus principle is 2,000 + 800, which is $2,800.
Hoped this helped.
