The distance could be calculated as follows:
d =
d =
d =
First, Make 2 equations to show each company in which "x" equals the number of days:
Andy's Rental Car = 20 + (30x)
Buddy's Rental Car = 36 + (28x)
Set it up like this:
20 + (30x) = 36 + (28x)
Now, solve for x by simplifying both sides of the equation and then isolating the variable.
x = 8
8 Days
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
Answer:
z=16
Step-by-step explanation:
-7(z-6)= -70
combine -7 with the bracket
-7z + 42 = -70
-42 -42
-7z = - 112
divide both sides by -7
-7z/-7 = -112/-7
z = 16
check
-7(z-6)= -70
-7(16-6)= -70
combine
-112+42= -70
-42 -42
-112 = -112
4 / (2/3) =
4 * 3/2 =
12/2 =
