Answer:
138 is the answer
Step-by-step explanation:
In order to find the perimeter, we use this formula
P=2(l+w)
And to find the width, we use this formula
w = P/2 - L = 18/2 - 3 = 6
So the width is 6
3 × 6 = 18
So thats why the perimeter of the top triangle is 18
We do 21 ÷ 3 = 7, 7 = scale factor
To find the perimeter of the bottom triangle, we do
the width of the top rectangle times 7
so 6 × 7 = 48
So the perimeter for the bottom triangle is
P=2(l+w)=2·(48+21)=138
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
Answer:
- 21 of multiple choice and 17 of short answer questions
Step-by-step explanation:
- Multiple choice = m
- Short answer = s
<u>Equations:</u>
<u>Solve for s by eliminating m. Subtract the double of the first equation from the second one:</u>
- 2m + 3s - 2(m + s) = 93 - 2(38)
- 3s - 2s = 93 - 76
- s = 17
<u>Find the value of m:</u>
