Hi There!

Evaluate 4x - 3y + (7x - 7y) when x = 6 and y = -1.

Remember to follow P.E.M.D.A.S

-------------------------------------------------

Solution:

= 4(6) - 3(-1) + (7(6) - 7(-1))

= 4(6) - 3(-1) + (42 - (-7))

= 4(6) - 3(-1) + 35

= 24 - (-3) + 35

= 21 + 35

= 56

-------------------------------------------------

Answer: C) 56

tiny-mole [99]

Answer:

1. Joelle spent 1¹/₂ hours reading and Rileigh spent 3/4 of that time.

To find out how much time Rileigh spent, multiply the fractions but first convert the improper fraction to a proper fraction:

= 1¹/₂ = 3/2

= 3/2 * 3/4

= 9/8

= 1¹/₈ hours

2. 1/10

3. They ate 1/6 of the donuts

They bought 18 donuts. 1/2 of 18 is 9. 1/3 of 9 is 3. To find the fraction, divide 3 by 18. Simplify the fraction. You are left with 1/6.

4. 2/3

1 1/3=4/3×1/2=4/6=2/3

And thats all on the pdf why are their only 4 Questions?
