Only 35:28 is equivalent to 5:4
Further explanation:
Given
5:4
We have to check each ratio, if it can be simplified to be equivalent to 5:4
<u>1:2</u>
The ration cannot be simplified in any way to 1:2 so it is not equivalent.
<u>8:14</u>
Simplified to: 4:7 => Not equivalent to 5:4
<u>35:28</u>
It can be simplified to 5:4 by dividing by 7.
Only 35:28 is equivalent to 5:4

Answer:
D and C
Step-by-step explanation:
Question 10: 86 - 6 = 80
80 ÷ 4 = 20
20 + 10 = 30
Question 11: 435 ÷ 3 = 145
145 x 7 = 1015
Answer:
angle s = 22
angle r = 117
angle q = 41
Step-by-step explanation:
so all of the angles equal to 180 degrees in a triangle
so you add all of t he angles like this:
x+5x+7x+2x-3=180
collect all of the like terms,
8x + 4 = 180
subtract 4 from both sides, which leaves you with 8x = 176
divide both sides by 8 leaving x on its own.
x = 22
angle s = 22
angle r = (5x22)+7 which is 117
angles q = (2x22)-3 which is 41
