Answer:
X=1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 1
X = Sales Tax Rate
350 * X = 22.75
22.75 / 350 = 0.065
0.065 = 6.5%
Answer:
y = -5x + 8
Step-by-step explanation:
Equation of a line: y = mx + b
x = slope
b = y-intercept or starting point
Slope = y^2 - y^2/x^2 - x^1
Slope = -12 - 43/4 - (-7)
Slope = -55/11
Slope = -5
b = y - y^1 = m(x - x^1)
b = y - 43 = -5(x - (-7))
b = y - 43 = -5x - 35
Add 43 to both sides
y = -5x + 8

Answer: C) x = 80</h3>
==================================================
Work Shown:
Let's cross multiply to get the following
14/20 = 56/x
14*x = 20*56
14x = 1120
x = 1120/14
x = 80
-------------------
As a way to check the answer, we can type 14/20 - 56/80 into the calculator and we should get 0. I'm taking advantage of the rule that if A = B, then A-B = 0. This trick is handy to check if two sides of any equation are equal to one another.
