Answer:

Step-by-step explanation:

9 - (-15) • 3 + 4 ÷ (-2)

9 + 15 • 3 + 4 ÷ (-2) = 9 + 15 • 3 + 4 ÷ -2

9 + 15 • 3 + 4 ÷ -2 = 9 + 45 + 4 ÷ -2

9 + 45 + 4 ÷ -2 = 9 + 45 + -2

9 + 45 + -2 = 9 + 45 + 2 (change the negative to positive)

9 + 45 - 2 = 54

54 - 2 = 52

What is the smallest integer that can be divided by the product of a prime number and 7 while yielding a prime number?

frozen [14]

Short Answer 28
If I'm reading this correctly it is 28.
2 is a prime number.
7 is also a prime

They are multiplied together to give 2*7 = 14

When you divide 28/14 you get 2 which is the smallest prime.

ZA and B are supplementary angles. If m A = (2x – 14) and m

Elena-2011 [213]

Answer:

∡ZA = 66°

Step-by-step explanation:

Suplementary angles sum 180°

ZA + ZB = 180°

then:

(2x - 14)° + (3x-6)° = 180°

2x + 3x - 14 - 6 = 180

5x - 20 = 180

5x = 180 + 20

5x = 200

x = 200/5

x = 40

then:

∡ZA = (2x - 14)

∡ZA = (2*40 - 14)

∡ZA = (80-14)

∡ZA = 66°
