Answer: angle A=40, Angle B=74, Angle C=66

Step-by-step explanation:

We all know that a triangle has 180 degrees.

3x-8+5x-6+4x+2=180

12x-12=180

12x=180+12

12x=192

x=16.

∠A=2(16)+8=40

∠B= 90-16=74

∠C = 5(16) -14= 66

A cookie contains 150 calories. If you eat no fewer than 2 cookies and no more than 8 cookies, how many calories will you consum
Wewaii [24]

Answer: 300cal ≤ y ≤ 1200 cal

Step-by-step explanation:

Let's define x as the number of cookies that you eat, and y as the number of calories you consume in those cookies.

"if you eat no fewer than 2 cookies..."

This is written as:

2 ≤ x

This means that x can be equal to 2, or larger than 2.

"...and no more than 8 cookies"

This is written as:

x ≤ 8

This means that x can be smaller than 8 or equal to 8.

If we combine those two, we have:

2 ≤ x ≤ 8

And we know that each cookie contains 150 calories, and rememer that these numbers represent number of cookies, then the numbers of calories will be:

2*150 cal  ≤ y ≤ 8*150 cal

300cal ≤ y ≤ 1200 cal.

x - 2y = 4

2y = x - 4

y = x/2 - 4/2

y = x/2 - 2
