9(7 + 8) = (9 x 7) + (9 x 8) = 63 + 72 = 135
Answer:
29-(2c+3)=2(c+3)+c=
We move all terms to the left:
29-(2c+3)-(2(c+3)+c)=0
We get rid of parentheses
-2c-(2(c+3)+c)-3+29=0
Step-by-step explanation:
Answer:
d(t) = -100t
Step-by-step explanation:
The general expression for the linear model is:

Since the submarine already starts at sea level, b=0:

The constant "m" is the rate at which the submarine descends in feet per minute. Considering depth as a negative quantity, m=-100

The linear model that represents the depth of the submarine relative to sea level, in feet, after t minutes is d(t) = -100t.
10-2/3=9 1/3 if you estimate that it would be 9
next it is 3 - 1/8= 2 7/8 estimate it would be 3
so 9 x 3= 27
