Answer:

14°

Step-by-step explanation:

→Since the temperature is a negative number, for the degree to reach 0, you must add with the same number.

→The temperature is -14, so to get it to 0, you add 14:

-14 + 14 = 0

Robert and his coworkers brought 11 work trucks to a service station for oil changes. While there they also put 6 gallons of gas

Free_Kalibri [48]

Answer:

The cost of an oil change for 1 truck was $42

Step-by-step explanation:

Let

x -----> the cost of an oil change for 1 truck

y -----> the cost of gas for 1 truck

z ----> the total bill

we know that

$z=11[x+y]$

we have

$z=\$694.32$

$y=(6)(3.52)=\$21.12$

substitute and solve for x

$694.32=11[x+21.12]$

$x=(694.32/11)-21.12$

$x=\$42$

What are the solutions to the equation 3(x – 4)(x + 5) = 0

Ne4ueva [31]

Answer:

x=4

x=-5

Step-by-step explanation:

in order for this to be equal to 0, 1 or both of the factors has to be 0, because anything multiplied by 0 is 0.

123 * 29382 * 8139* 0 = 0

x-4 = 0

x = 4

x+5 = 0

x=-5
