Evaluate in the order of operations! PEMDAS
Parentheses
Exponents
Multiply/Divide (left to right)
Addition/Subtraction (left to right)
Example: 5 x 2 / 5 + (6 x 3)
1. Evaluate parentheses: 6 x 3 = 18
2. Multiply and divide: 5 x 2 = 10, 10 / 5 = 2
3. Add and subtract: 2 + 18 = 20
4. We're done: 20
The answer is to isolte the unknown on one side by itself so
I hope you know how number lines because It is hard to do on branly so
1.
h-16 <u><</u>-24
add 16 to both sides
h<u><</u>8

2. y+6 <u>></u>-13
subtract 6
y<u>></u>-19

3. -3<n-8
add 8 to both sides
5<n

It is a rational number in the form of a decimal fraction.
Answer:
Surface Area is 56π cm²
Step-by-step explanation:
The area for a cylinder's surface area is
a=2πrh+2πr²
The cylinder base's radius is 4 cm
The cylinder's height is 3 cm
Putting into the equation:
a=2×π×4×3+2×π×4²
a=2π×4×3+2×π×4²
a=8π×3+2×π×4²
a=24π+2×π×4²
a=24π+2×π×16
a=24π+2π×16
a=24π+32π
a=56π
The surface area of the cylinder is 56π cm².
Answer:
R = 101
S = 131
Step-by-step explanation:
First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.
T=180-128
T=52
You also know that all angles in a triangle equal to 180
Use that to find angle S
180 = R+S+T
180 = 79 + S + 52
180 - 79 - 52 = S
49 = S, exterior S = 180-49 = 131
Exterior R = 180 - 79 = 101
Now add all your exteriors
