Solve the equation 12+ 0.35×=20.05

lbvjy [14]

12 + 0.35X = 20.05
12 + 0.35X - 12 = 20.05 - 12
0.35X = 8.05
0.35X/0.35 = 8.05/0.35
X = 23
Hope this helps!!

What is the slope of the line shown below?

Lesechka [4]

Answer:

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 2) and (x₂, y₂ ) = (3, 9)

m = $\frac{9-2}{3+4}$ = $\frac{7}{7}$ = 1 → A

Sales tax is 7% what is the amount of sales tax you would pay this bill

AleksAgata [21]

% means per 100

so when figuring out percents it's good to use 100

so

on $100 7% would mean $7

on $50 7% would mean $3.5

in $200 7% would mean $14
