Answer:
The solution is (2,6)
Step-by-step explanation:
Let
x-----> the number of hours to change a fuel injection unit
y-----> the number of hours to change a transmission
we know that
5x+10y=70 -----> equation A
8x+8y=64 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2,6)
see the attached figure
To solve, we add the 4 numbers (including the one unknown) and divide that total by 4, and this equals the desired overall average of 154.
x= score needed on 4th game
(149 + 162 + 152 + x)/4= 154
add in parentheses
(463 + x)/4= 154
multiply both sides by 4; 4 "cancels out" on the left side
463 + x= 616
subtract 463 from both sides
x= 153
ANSWER: 153 is the score needed on the 4th game to reach the desired overall average of 154.
Hope this helps! :)

Answer:
Glados makes $44.76 per hour.
Step-by-step explanation:
Given:
Total hours Glados worked this week = 38.4
Amount earned by Glados this week = $1,718.64
To find her hourly earnings for the week.
Solution:
We will use unitary method to find the unit rate.
If for 38.4 hours Galdos earned = $1,718.64
Then for 1 hour she will earn = 
Thus, Galdos' hourly earnings for the week = $44.76
