Answer: width = 21, length = 47
<u>Step-by-step explanation:</u>
Length (L) = 2w + 5
width (w) = w
Perimeter (P) = 136
P = 2L + 2w
136 = 2(2w + 5) + 2w <em>substituted the given values above</em>
136 = 4w + 10 + 2w <em>distributed 2 on the right side</em>
136 = 6w + 10 <em>added like terms (4w and 2w)</em>
126 = 6w <em>subtracted 10 from both sides</em>
21 = w <em>divided both sides by 6</em>
Length (L) = 2w + 5
= 2(21) + 5
= 42 + 5
= 47
Answer:
c) $9.35 dollars
Step-by-step explanation:
1.25 + 7.25 = 8.50
8.50 x 0.10 = 0.85
8.50 + 0 .85 = $9.35
(May i please have brainleist i am trying to rank up :\ )
17.5
This is because if you do the math: (7/40)*100 you get 17.5!
So divide 7 by 40 and then multiply it by 100!
7/40=0.175
0.175*100=17.5
Answer: The altitude of the smaller triangle is 14.4 inches
Step-by-step explanation:
Two similar triangles have a scale factor of 3:5. This can also be expressed as 3/5
The altitude of the larger triangle is 24 inches. The difference in altitude or other lengths of the two similar triangles is linear. To determine the altitude of the smaller triangle, let us assign x to the altitude of the smaller triangle. It means that 3:5 = x : 24. Therefore
3/5 = x/24
Cross multiplying, it becomes
5x = 3×24 = 72
x = 72/5 = 14.4
