an indy car driver has to be a certain height to fit into the race car. The following inequality 175<=3x-17<=187, where x
enot [183]

Given inequality : 175 ≤ 3x-17 ≤ 187, where x represents the height of the driver in inches.

Let us solve the inequality for x.

We have 17 is being subtracted in the middle.

Reverse operation of subtraction is addition. So, adding 17 on both sides and also in the middle, we get

175+17 ≤ 3x-17+17 ≤ 187+17

192  ≤ 3x ≤ 204.

Dividing by 3.

192/3  ≤ 3x/3 ≤ 204/3.

64 ≤ x ≤ 68.

Therefore, the height of the driver should be from 64 to 68 inches  to fit into the race car.

X<9.7 on a line graph
fiasKO [112]
The inequality x < 9.7 tells us x needs to smaller than 9.7.
A number like 5 will be fine. Because 5 < 9.
But someone like 10 won't be fine.
Because 9 < 10.

Even 9.7 won't be suffice.

Because 9.7 < 9.7 does not make sense. If it was 9.7 <= 9.7 then it would be fine.

The ratios of the measures of the angles in triangle XYYZ is 7:13:16. Find the measures of the angles
kirza4 [7]

Answer:

let the angles be 7x , 13x , 16x

7x + 13x + 16x = 180 ( sum of angles in a triangle is 180 degree)

36x = 180

x = 180 / 36

x = 5

therefore the angles are:

7 X 5 = 35 degree

13 X 5 =  65 degree

16 x 5 =  80 degree
