In the given equation, which number is the coefficient?

• 2
• 5
• -1
• 7

In the equation 4y +-9 =-36

y = -4

• True

• False

6.    -3x + 5 = -13

• x = -5
• x = 2
• x = -6
• x = 6

1/10 times a number plus 4 is 6.

• (1/10)n + 4 = 6; The number is 10.

• (1/10)n + 4 = 6; The number is 20.

• 1/10 + 4n = 6; The number is 15.

• 1/10 + 6n = 4; The number is 6.7

2 times the sum of 1/2 of a number and 3 is 16.

• 2(0.5 + 3n) = 16; The number is 1.5

• 2(0.5) + 3n = 16; The number is 5.

• 2(0.5n + 3) = 16; The number is 10.

• 2 + 0.5 + n = 3; The number is 0.5

A number n squared plus 12 is the same as the quotient of p and 4.

• n² + 12 = 4p

• 2n + 12 = p + 4

• n² + 12 = p ÷ 4

• n² + 12 = p(4)
