Answer:
t = -1
Step-by-step explanation:
15(t+2)+9t=6
15t + 30 + 9t = 6
combine like terms
24t +30 = 6
subtract 30 both sides
24t = -24
t = -1
22-5(6v-1) = -63
22- 30v + 5 = -63
27 -30v = -63
subtract both sides by 27
-30v = -90
divide it by -30
v = 3
b is just a variable, which is just a term for a value that could change. It could be anything
Answer: 40
Step-by-step explanation:
Answer:
option (4) is correct.
Coefficient in the given expression
is 6 and 
Step-by-step explanation:
Consider the given expression 
We have to determine the coefficient in this expression,
Coefficient is a constant term that is placed before variable term in an expression. example 4x , here 4 is coefficient.
In the given expression
, we have two variables a and b,
So coefficient of a is 6 and coefficient of b is 
Thus, option (4) is correct.
Coefficient in the given expression
is 6 and
