Harvey the Huge once lifted a box filled with 100 bricks and 50 rocks. Each brick weighed 10 pounds. The rocks were all fairly small. What is the total weight of what Harvey lifted? A: too much or B: too little​

50(20 + t) pounds

Step-by-step explanation:

Let the weight of each fairly small rock be represented by t pounds.

Each brick weighs 10 pounds, then:

the weight of 100 bricks = 100 x 10

                                        = 1 000 pounds

Each rock weighs t pounds, then:

the weight of 50 rocks  = 50 x t

                                       = 50t pounds

Therefore, the total weight of what Harvey lifted = total weight of bricks + total weight of rocks

                                          = 1 000 + 50t

                                          = 50(20 + t) pounds

hope this help:)

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
