Which expression is equivalent to
-7(j + 2)
A) -7(j) + 2
B) -7(j) + -7(2)
B) -7(j) + -7(2)
(This is equivalent. It is the intermediate step of the distributive property to eventually get the answer -7j -14)
The high temperature is 92 degrees and the low temperature is 59 degrees. This is the change in temperature.

Jack made $150 selling old books. If each book sold for the same amount [amount not given], which equation could be used to find p, the price at which each book sold?
A) 5=150p B) 150=5p C) p/5 = 105
B. 150=5p
(You use division to solve it, so you should see multiplication in the equation. Inverse Operations.)
There were 20 people over at dinnertime. They each were hungry enough for 3 pieces of pizza. If each pizza I order will have 8 slices, this is how many total pizzas I should order.
What is 8 pizzas total?
(20 people x 3 pieces=60 slices)
60 divided by 8 = 7.5, so I should order 8 pizzas total
Solve for 200 + 50d < 800 and indicate if it would be graphed with an open dot or closed dot.
What is d < 12?
What is closed dot?
(Because 12 is included. 12 is part of the solution set.)
Simplify -2xy3 + 4xy3 +5xy -xy -7xy
2xy3 - 3xy
The temperature started at 43 degrees but it got colder and the temperature dropped to -15. Give the change in temperature.
58 degrees
(It takes 43 degrees to get down to zero, and then 15 MORE degrees down to get to -15, so it was a total drop, or total change, of 58 degrees.)
Solve for the variable 3(x + 15) = 15

Christie made $20 selling lemonade. If each cup sold for the same amount [amount not given], which equation could be used to find c, the cost at which each cup of lemonade sold?
A) 20=.50c B) c/.50 = 20 C) .50=20c
A) 20=.50c
(You use division to solve it, so you should see multiplication in the equation. Inverse Operations.)
