Answer:

-12t + 21

Step-by-step explanation:

9-4(3t-3)

In order to get rid of the parenthesis you must take -4 and multiply it by the number(s) inside the parenthesis

So, -4 times 3t equals -12t and -4 times -3 equals +12

9-12t+12

Combine like terms

-12t + 21

Hope this helps!

Alex stocks up for winter. He buys 32 cans of vegetables. He pays 80 cent per can for tomatoes and 40 cents per can for corn, fo

lara31 [8.8K]

X = # of cans of tomatoes, y = # of cans of corn

x + y = 32.....y = 32 - x
0.80x + 0.40y = 18

0.80x + 0.40(32 - x) = 18
0.80x + 12.8 - 0.40x = 18
0.80x - 0.40x = 18 - 12.8
0.40x = 5.2
x = 5.2 / 0.40
x = 13 <=== 13 cans of tomatoes were bought

leaving (32 - 13) = 19 cans of corn bought
