Answer: Simplifying
17.75x + 24 = 18.95x + 18
Reorder the terms:
24 + 17.75x = 18.95x + 18
Reorder the terms:
24 + 17.75x = 18 + 18.95x
Solving
24 + 17.75x = 18 + 18.95x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-18.95x' to each side of the equation.
24 + 17.75x + -18.95x = 18 + 18.95x + -18.95x
Combine like terms: 17.75x + -18.95x = -1.2x
24 + -1.2x = 18 + 18.95x + -18.95x
Combine like terms: 18.95x + -18.95x = 0.00
24 + -1.2x = 18 + 0.00
24 + -1.2x = 18
Add '-24' to each side of the equation.
24 + -24 + -1.2x = 18 + -24
Combine like terms: 24 + -24 = 0
0 + -1.2x = 18 + -24
-1.2x = 18 + -24
Combine like terms: 18 + -24 = -6
-1.2x = -6
Divide each side by '-1.2'.
x = 5
Simplifying
x = 5
Step-by-step explanation:
Graph #1 is (1/4)^x
graph #2 is -(1/4)^x
graph #3 is 4^x
graph #4 is -4^x
Step-by-step explanation:
Let assume that
Cost of 1 burger = $ x
Cost of 1 doughnuts = $ y
According to statement, 9 burgers and 1 doughnut cost $ 31.30
According to statement again, 3 doughnuts and 6 burgers cost $ 26.70
On substituting the value of y from equation (1), we get
So,
Cost of 2 burgers = 3.2 × 2 = <u>$ 6.4</u>
