Answer:
y is less than or equal to -12
y<=-12
Step-by-step explanation:
Answer 6 hours
Reason
7x + 9.50 = 55
-9.50. -9.50 subtract from both sides
_____________
7x = 45.50
Divide both sides by 7 to isolate x
X = 6.5
So he can rent for 6 hours (the .5 would be charged as a full hour per the problem)
4.72 x 1 = 4.72
8 x X =8x
We need to let the X alone so
4.72 divided 8 = 0.59
1 battery = 0.59
Answer:
first one: 8
second one: 3
Step-by-step explanation:
-3x + y = -24 |÷(-3x)
y = 8
y = 7x + 22 |-y
(y would be 1; the 7x moves to the other side.) meams:
7x = 21 |÷7
x = 3
Answer:
Highest to lowest the numbers would be (1/2)^2, (-1)^2, -1 2/5 Putting the "bar 4" somewhere
First we need the numbers exact value meaning
-1 2/5 = -1.4
(-1)^2 = -1
?4 = ?
(1/2)^2 = 0.25
