I think it’s 5 but don’t get mad if it’s wrong
Answer:
y=150x
Step-by-step explanation:
let me know if its wrong
Answer:
<u>5x+13</u> ÷ 36 = 6x-2 ÷ 30
5x+13 ÷ 6 = 6x-2 ÷ 5
25x+65=36x-12
11x=77 → x=7

Answer:
C.
Step-by-step explanation:
Easiest and fastest way to determine your answer is to graph the systems of inequalities on a graphing calc. Once you do so, you should be able to see that Choice C is the correct answer.
Answer:
22.5 miles per hour
Step-by-step explanation:
<u>Given system of equations</u>
5(s-w)=900
4(s+w)=900
<u />
<u>Set equations equal to each other</u>
5(s-w)=4(s+w)
5s-5w=4s+4w
s-5w=4w
s=9w
<u>Solve for w using the substitution s=9w</u>
4(s+w)=900
4(9w+w)=900
4(10w)=900
40w=900
w=22.5
Therefore, the speed of the wind is 22.5 miles per hour
