Solve the equation -6 = -9 – 3x for x. A.-2 B.-1 C.0 D.1

B. -1

Step-by-step explanation:

-6 = -9 - 3x

1. get the variable x by itself by adding 9 to both sides

-6 = -9 - 3x

+9    +9

3 = -3x

2. solve for x by dividing by -3 on both sides

3 = -3x

/-3  /-3

3/ -3 = -1

x = -1

angle uzt is congruent to angle tzy. angle vzw is congruent to angle yzx.

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
