Which values are solutions 4x greater than or equal to 35
Mamont248 [21]

Answer:

\frac{5}{1/2}, 12, \frac{8}{3/4}, 10

Step-by-step explanation:

4x\geq 35

x \geq \frac{35}{4}

x \geq 8 \frac{3}{4}

so

\frac{5}{1/2} = 10

12

\frac{8}{3/4} = 10.66

and 10

Because saying 5 over 1/2 is saying 5 divided by 1/2 which is the same as saying 5 * 2

8 over 3/4 is 8 divided by 3/4 which is 8 * 1.33.

A fraction is division. If you mean 5 and 1/2 as well as 8 and 3/4 then remove 5 and 1/2 from the answer.

15 POINTS!!!!!! PLEASE HELP!!The length of a rectangle is four times its width. If the perimeter is at most 130 centimeters, wha
marin [14]
Here is the information we have:

1. The perimeter is at most 130 cm.
2. The length of the rectangle is 4 times the width.
    We can let l stand for length and w for width.

The formula for the perimeter of a rectangle is 2l + 2w.
We have to change the formula a bit.
The length of this rectangle is going to be 4 times the width
So, replace 2l with 2(4w).

Then make this equation equal to 130.

2(4w) + 2w = 130 ; Start
8w + 2w = 130      ; Distribute the 2 across the 4w
10w = 130             ; Combine the like terms 8w and 2w
w = 13                   ; Divide both sides by the coefficient of w. Which is 10
