Answer:-18xy+2x-13y
Step-by-step explanation: combine like terms
Multiply each hourly rate by x ( time to complete the work) add it to the service call for each and then set the equations equal:
50 + 40x = 30 +45x
Subtract 30 from both sides:
20 + 40x = 45x
Subtract 40x from both sides:
20 = 5x
Divide both sides by 5
x = 4
The length is 4 hours.
Answer:
B
Step-by-step explanation:
3x-7 <-4
Firstly solve this.
+7 +7
3x<3
÷3 ÷3
x<1
And because the inequality symbol isn't "equal to", the circle isn't coloured in.
The line will go from 1 to behind 0
Hi there!
To write 3 x 3/8 as a unit fraction it is 9/8.
To write 3 x 3/8 as a whole number it is 1 1/8.
Explanation:
When you multiply 3 x 3/8 you get 9/8.
But when you make it to a proper fraction you get 1 1/8.
Hope this helps ;)
D because if you multiply y 8 times it will no longer be doubling the area
