Answer:
x = -.25
Step-by-step explanation:
x - 3.75 = -4
x = -.25
Your equation is wrong
the first is suppoosed to be 3(45), you wrote 5(45) but it should be 3(45), it's 3 trips, not 5
the other part is right tho, it is 6h
so 3(45)+6h=303 is the right equation
remember, you can do anything to an equation as long as you do it to both sides
so first expand 3(45)
3(45)=135
135+6h=303
minus 135 both sides
6h=168
divide both sides by 6
h=28
the hourly rate is $28 per hour
Area is L x W and being a square, the length and width would have to be the same, so L x W = 40 and the answer would be the best estimate and while 6.5 is 42.25, it’s not as close as 6.3 39.69
The answer is B-6.3
7/9 =70/90 and 3/10= 27/90
