<em>GCF = 38</em>
- Step-by-step explanation:
<em>38 = 2×19</em>
<em>76 = 4×19 = 2²×19</em>
<em>114 = 2×3×19</em>
<em>GCF = 2×19 = 38</em>
Answer:
22
Step-by-step explanation:
21.6 would round up because 6 is closer to 10 than it is 0
The regular selling price per unit for the laptop is $298.6.
<h3>How to calculate the price?</h3>
Let the regular price per unit be x.
The expense is 19% of the selling price and profit is 25% of the selling price. This will be illustrated as:
x + (19% × x) + (25% × x) = 430
x + 0.19x + 0.25x = 440
1.44x = 430
Divide
x = 430 / 1.44
x = 298.6
The price is $298.6

Answer:
x=2, y=4
Step-by-step explanation:
When using elimination, the objective is to elimate one variable. In this case, we see that "y" can easily be eliminated by adding the two equations together since you will get 3y + (-3y) which will eliminate y because the value would become 0, letting us solve for x.

Then we get
, because the y's will eliminated, and 8x+7x is 15x, and 28+2 is 30.
Then divide by 15 on both sides and you get x=2
If x=2, then we can substitute that value into any of the previous given equations and find the value of y.
8×2 +3y = 28
16+3y=28
3y=12
y=4
So the answer to your system of equations would be x=2, and y=4
You can substitute the answers we found to see that they satisfy the equation.
Hope this helped.
Answer:
y=34x+2.625
y=34x+2.75
y=−34x+1.25
y=34x+1.25
y=−34x+2.75
Correct answer:
y=−34x+2.75
