Answer:
Explanation:
1).
2). 7t - 22
3). 5(2t + 1) + (-7t + 28) = 10t + 5 - 7t + 28
= (10t - 7t) + 33
= 3t + 33
4).
5).
6).
7). 3(3t - 4) - (2t + 10) = 9t - 12 - 2t - 10
= (9t - 2t) - ( 12 + 10)
= 7t - 22
8). 3t + 33
Therefore, equivalent expressions are,
a).
b). 7t - 22 = 3(3t - 4) - (2t + 10)
c).
d). 5(2t + 1) + (-7t + 28) = 3t + 33
