Answer:
15x + 180 ≥ 900
x ≥ 48
Step-by-step explanation:
x = amount of laptops needed to sell.
Equation:
15x + 180 ≥ 900
15x ≥ 720
x ≥ 48
Check:
15(48) + 180 = 900
720 + 180 = 900
900 = 900 (It's good, she needs to make at least 900, so she needs to sell at least 48 laptops).
Answer:
ok so the answer o Y is -8 bc 4-12 = -8 so really is -8
Step-by-step explanation:
Answer:
6 classes
Step-by-step explanation:
Let n represent the number of classes. Then the total study time is ...
(2/3)n = 4 . . . . . hours
n = (3/2)(4) = 6 . . . . . . . multiply by the inverse of the n coefficient
Sung Lee has 6 classes.
Multiply 62 by 3 and you get 186
The first thing we must do is solve the problem step by step to choose the correct option.
Step 1:
Clear y from the first equation:
-5x + y = 6
y = 5x + 6
Step 2:
Replace this value of y in the second equation:
3x-y = 14
Substituting:
3x- (5x + 6) = 14
answer
the resulting equation after an equivalent expression for y is substituted into the second equation is
3x- (5x + 6) = 14
