Answer:
x=3
Step-by-step explanation:
In order to solve this kind of equation, you need to be able to understand what the question is asking. This question is asking what value of X will make both sides equivalent to each other?
<em>In order to find out, you need to get X by itself. </em>
The first step is to subtract 115 from both sides.
7x+115=136
-115 | -115
7x=21
Now, the X value is by itself with another value on the other. With this part, you need to divide both sides by 7.
7x=21
/7 | /7
x=3
This is because you have 7 X's and you need to have only 1 of the X's.
Let me know if this was helpful or if you need any more help. Have a nice day. :)
Less than or equal to first equation (solid line)

Answer:
$156.25
Step-by-step explanation:
A good strategy in my opinion is the "finders" strategy
50$ = 32%
x = 100%
First Multiply 100 by 50
100 x 50 = 5,000
Then Divide 5,000 with 32
5,000/32 = $156.25
If you want to check, then...
156.25 x 32 = 5,000
<em />
<em>x = $156.25</em>
Hope this helps!

Answer:
(a) not proportional
(b) k = 7/8
Step-by-step explanation:
When a linear equation is of the form ...
y = mx + b
with b ≠ 0, the relation is NOT PROPORTIONAL.
__
If b=0, so the equation is of the form ...
y = kx
then the relation IS PROPORTIONAL. The constant of proportionality is k.
__
(a) Not proportional
(b) Proportional with k = 7/8
