Answer:
She should buy one that accords to her budget and her needs
The original cost 35 more than this one. Therefore:
149+
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>
Because there are two variables, we cannot solve for an exact value of s.
1.5s - 4 = t
Add 4 to both sides.
1.5s = t + 4
Divide both sides by 1.5
s = (t + 4)/1.5
