Answer: 112 degrees
Step-by-step explanation: Because they are supplementary, they add up to 180 degrees. So it would be 3x+16+2x+4=180. Add the variables and the constants together. 5x+20=180. Solve the equation, and x=32. Then plug x into 3x+16. The answer is 112.

Answer:
The probability of choosing two red cards would be 3/8
Step-by-step explanation:
The probability of choosing 1 red card is 10/16; the probability of choosing a second red card would then be 9/15.
P(2 red) = 10/16(9/15) = 90/240 = 3/8.
Answer:
The correct answer is c) 18 centimeters
Step-by-step explanation:
Given:
A = 18 cm²
We know that the formula for calculating area of a rectangle is
A = a · b where a is length and b is width
Possible choices is 6 · 3 and 9 · 2
Formula for calculating perimeter is
P = 2 ( a + b)
P₁ = 2 (6 + 3) = 2 · 9 = 18 cm²
P₂ = 2 (9 + 2) = 2 · 11 = 22 cm²
The obvious choice is P₁ = 18 cm²
God with you!!!
