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

$694.32=11[x+21.12]$

$x=(694.32/11)-21.12$

$x=\$42$

Which of the following lists is in the correct order from smallest to largest? -13, -19, -21, -24 11, -12, 15, -19 -7, -3, 6, 2

seraphim [82]

Answer:

-24, -21, -19, -19, -19, -14, -13, -12, -7, -3, 2, 5, 6, 11, 11, 15

Step-by-step explanation:

Hey there!

To put the numbers in least to greatest form, you need to put the biggest numbers with a - sign in front of it

This means negative

Negative means below zero

Then after putting the big negative numbers, you put positive numbers going from smallest to largest

So the numbers in least to greatest is -24, -21, -19, -19, -19, -14, -13, -12, -7, -3, 2, 5, 6, 11, 11, 15
