Answer:
6.67 miles per hour
Step-by-step explanation:
9 ≤ |4x + 7|
9 ≤ 4x + 7
9 - 7 ≤ 4x
2 ≤ 4x
2/4 ≤ x
<h2>
1/2 ≤ x</h2>
9 ≤ |4x + 7|
9 ≤ -(4x + 7)
9 ≤ -4x - 7
9 + 7 ≤ -4x
16 ≤ - 4x
16/-4 ≤ x
<h2>-
4 ≤ x </h2>
<h2>
{-4 ≤ x ≤ 1/2} </h2>
Answer:
58 degrees
Step-by-step explanation:
(x+45)+(x+66)=95
2x+45+66=95
2x+111=95
2x=95-111
2x=-16
x=-16/2
x=-8
x+66=-8+66=58
It is -7.83 because you distribute the -6 to the n and the 1 inside the parentheses which makes you get -6n-5=42. Since 5 is negative you add it to -5 and the 42 on the other side of the equation which turns out to -6n=47. You then divide -6 on both sides of the equation. -6n divided by -6 cancels out so 47 divided by -6 equals -7.83333333 which rounds to -7.8
