Solve negative 5 over 2, the whole multiplied by x minus 5 equals negative 55.

astraxan [27]

Answer:

-24

Step-by-step explanation:

$- \frac{5}{2} x \: - 5 = 55$

Multiply through by the denominator (that is, 2)

$= 2 \times ( - \frac{5}{2} x) \: - 5(2) = 55(2)$

$= - 5x - 10 = 110$

Collect like terms

$- 5x \: = 110 +10$

$- 5x = 120$

Divide through by - 5x

$\frac{ - 5x}{ - 5} = \frac{120}{ - 5}$

$x = - 24$

A truck rental is $30 plus $.30 /mi. Find out how many miles Ken traveled if his bill was $55.20 .

tangare [24]

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

Let's consider the information given:

rental price: $30 + $0.30/mile
total bill for Ken: $55.20

Let's setup an equation for the cost

set 'x' as number of miles traveled

$\hookrightarrow Cost = 30 + 0.3x$

set that equal to the total cost or bill and solve

$30 + 0.3x = 55.2\\0.3x = 25.2\\x=84$

Ken must have traveled 84 miles

Answer: 84 miles

Hope that helps!
