Answer:
-5 and +5
Step-by-step explanation:
add twelve to both sides
New equations: 2x= -+10
Divide by 2 on both sides
x=-5, +5
$12.6 -- 25% of 12.6 is exactly $3.15
I did this by taking 3.15 / 0.25
Ok so what you will do is 3-18 then you will add 1 and make is to 400X1
Answer:
- D. l = 3 || 4 < c < y || 8l + 7.5c ≥ 70
Step-by-step explanation:
<h3>Work at library</h3>
- Time = 3 hours ⇒ l = 3
- Payment = $8 per hour
- Total payment = 8l
<h3>Work at coffee shop</h3>
- Time = between 4 and 7 hours ⇒ 4 < c < 7
- Payment = $7.5 per hour
- Total payment = 7.5c
Target income = at least $70 daily
<u>So the system as per above parameters:</u>
- l = 3
- 4 < c < y
- 8l + 7.5c ≥ 70
Correct option is D
