Answer:
option D
D. x = 5, y = 2
Step-by-step explanation:
Given in the question two equation,
Equation 1
5.3x + y = 28.5
Equation 2
4.2x + 3.1y = 27.2
rearrange equation 1 in terms of y
y = 28.5 - 5.3x
Substitute the value of y in equation 2
<h3>4.2x + 3.1(28.5 - 5.3x) = 27.2</h3>
4.2x + 88.35 - 16.43x = 27.2
4.2x - 16.43x = 27.2 - 88.35
-12.23x = -61.15
x = 61.15/12.23
x = 5
put value of x in any of the equation
<h3>5.3(5) + y = 28.5</h3>
y = 28.5 - 26.5
y = 2
Y is the number of movies
x is the number of hours
It takes 2 hours per movie
Thus:
y = x/2
2y = x
x - 2y = 0
The answer is C
We must multiply and divide before adding and subtracting here. Working from left to right, we get:
8 + 15 - 5 = ?
8 + 10 = ?
18 (answer)
So 5 liters of natural for every 7 synthetic, so 5 / 12 liters are natural oil.
so; 684 × (5/12) = 285 liters of natural oil

Answer:
Employers will look to see which workers are applying themselves. They want workers who are flexible, have good attitudes, are loyal to their company, practice good judgement, and are unselfish. Workers who go out and do work that is not formally assigned to them and expand the scope of their responsibilities are rewarded with promotions. Workers who maintain extensive professional networks and learn new skills are also prime candidates for promotion.
This was the example answer. Hope this helps!! HAVE AN AMAZING DAY!
