Answer:
5
Step-by-step explanation:
4(x+3) is 4x+12
2x+22=4x+12
-2x from both sides
get 22=2x+12
-12 from both sides
get 10=2x
divide by 2 to both sides
get 5
im assuming you need to know the length of the 7 equal bits of ribbon. the original length of ribbon - the length of ribbon left over = 7x
170.9-16.2=154.7. 154.7/7=x = 22.1
each length of ribbon was 22.1 inches long
The time for the job for which the two company are the same is 16
<h3>How to form the equation and find the cost?</h3>
A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,
using linear equation,
y = mx + c
where
Therefore,
y = 345 + 16.25x
Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,
y = 213 + 24.50x
Hence, the time when both cost are the same is as follows;
213 + 24.50x = 345 + 16.25x
213 - 345 = 16.25x - 24.50x
-132 = -8.25x
x = 132 / 8.25
x = 16

Answer:
5.) 39
6.) 52
Step-by-step explanation:
5.) 90-51= 39
6.) 74 + 34= 108
180-108= 72
56+72= 128
180-128= 52
x=52
Ok. This is called a Coordinate Plane (aka line plots). Your teacher is asking to find the number on those plots.
You have your X and Y axis.
You go over to X before going to Y
So I work my way up so your first one is
1,2
Second is
-2,4
Third is
2,6
and the last one (the top plot)
1,8
Hope this helped!
