Answer:
A) x=4
B) x=35/2
Step-by-step explanation:
calculate the product
A) 5x/2+1=11
multiply both sides of the equation by 2
5x+2=22
move the constant to the right hand side and change its sign
5x+22-2
now subtract the numbers
5x=20
now didvide both sides
5x=20
x=4
B)
calculate the product
2x/7-3=2
multiply both sides of the equation by 7
2x-21=14
move the constant to the right hand side and change its sign
2x=14+21
add the numbers
2x=35
now divide both sides of the equation by 2
x=35/2
Answer:
<em>options: A,C,E </em>are correct.
Step-by-step explanation:
We have to find the expression equivalent to the expression:
we know that: 
Hence,
-----(1)
A) 
(same as(1))
Hence, option A is correct.
B) 7 ; which is a different expression from (1)
Option B is incorrect.
C) 
(Same as (1))
Option C is correct.
D) 
which is a different expression from (1)
Hence, option D is incorrect.
E) 
; which is same as (1)
Hence, Option E is correct.
F) 
; which is not same as expression (1)
Hence, option F is incorrect.

Answer:
cost when 400 miles is driven is $143.
Step-by-step explanation:
Model for cost calculation: C=0.32m + 15
We have to find cost when no. of miles driven is 400.
To find that cost we need to plug 400 in place of m.
C=0.32m + 15
=> c = 0.32*400 + 15
=> c = 128 + 15 = 143
Thus, cost when 400 miles is driven is $143.
Answer:
Step-by-step explanation:
first distribute the ^3, -3^3=-27, for the variables, (x^y)^3=x^(3y) so (b^2)^3=b^6 and (c^-6)^3=c^-18. now we have 
. Next we have to get rid of the negative in c^-18. x^-y=1/x^y so c^-18=
, plug it in and you get
