Question

Please help on at least one I'm really stuck and its due soon please :)

Which expression is equivalent to 3(−2.4y − 16.5)?

0.6y − 16.5
0.6y − 13.5
−7.2y − 16.5
−7.2y − 49.5


Which expression is equivalent to the expression quantity negative 9 over 5 times t plus 3 over 12 end quantity minus expression quantity negative 2 over 15 times t plus 5 over 6 end quantity?

negative 25 over 15 times t plus 7 over 12
negative 25 over 15 times t minus 7 over 12
25 over 15 times t plus negative 13 over 15
7 over 5 times t plus 7 over 15

Simplify the expression.

the linear expression quantity negative 1 over 5 times r minus 4 minus 2 over 3 times r end quantity minus the linear expression quantity negative 4 over 5 times r plus 9 end quantity

negative 25 over 15 times r minus 5
5 over 7 times r plus negative 13
negative 1 over 15 times r minus 5
negative 1 over 15 times r plus negative 13

Answer 1

Answer: 3(−2.4y − 16.5) = -7.2y - 49.5

Explanation:

Answer 2

3(−2.4y − 16.5) = -7.2y - 49.5

Explanation:

1:negative 25 over 15 times t minus 7 over 12 or

(-9/5t + 3/12) - (-2/15t + 5/6) = -25t/15 - 7/12

2: negative 1 over 15 times r plus negative 13 or

-1r/15 + -13
