The product of two numbers is 21. if the first number is -3, which equation represents this situation and what is the second number? a. the equation that represents this situation is x − 3 = 21. the second number is 24. b. the equation that represents this situation is 3x = 21. the second number is 7. c. the equation that represents this situation is -3x = 21. the second number is -7. d. the equation that represents this situation is -3 + x = 21. the second number is 18.

Option C

The equation that represents this situation is -3x = 21

The second number is -7

Solution:

The first number is -3

The product of two numbers is 21

Let the second number be "x"

The equation that represents this situation is:

Product of first and second number = 21

Thus the equation is found

Solve the equation

-3x = 21

Divide both sides by -3

Thus the second number is -7

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
