Answer:
17s−109t
Step-by-step explanation:
Let's simplify step-by-step.
9(3s−3t)−2t−10(8t+s)
Distribute:
=(9)(3s)+(9)(−3t)+−2t+(−10)(8t)+(−10)(s)
=27s+−27t+−2t+−80t+−10s
Combine Like Terms:
=27s+−27t+−2t+−80t+−10s
=(27s+−10s)+(−27t+−2t+−80t)
=17s+−109t
Answer: question 6
4/7*8/10 =
first multiply the numeratores the the denominatos.
4*8=32 so this will be numerator.
7*10=70 this is denominator.
so answer is 32/70
same way question 7 is 28/40
question 8
11/2 *9/4 = 99/8= 12 3/8
question 9
convert to improper
9/5*7/3= 63/15 4 3/15
question 10
21/8*16/7= 336/56= 6/6
