Answer:
in the ordered pair; ( x = 27/4 , y = 1/4 )
Step-by-step explanation:
Given that:
The system of the equation shown below is:
-2x - 14y = 10
2x + 2y = 14
We are to use the elimination method to determine the ordered pair.
From the above equation:
-2x - 14y = 10 --- (1)
2x + 2y = 14 --- (2)
Add both equation 1 and 2 together in order to eliminate x, then we can solve for y first.
-2x - 14y = 10
<u> 2x + 2y = 14 </u>
<u> 0 - 16y = -4 </u>
<u />
- 16 y = - 4
divide both sides by - 16, Then:
-16y /-16 = -4/-16
y = 1/4
Since y = 1/4, Then from equation (2), x will be :
2x + 2y = 14
2x + 2(1/4) = 14
2x + 1/2 = 14
2x = 14 - 1/2
2x = 13.5
x = 13.5/2
x = 27/4
Thus, in the ordered pair; ( x = 27/4 , y = 1/4 )
113.5+22.41 = 135.91 if that’s what’s your asking :)
Answer:
5x+6=3
Step-by-step explanation:
"A number" is a variable.
"Sum" is addition.
"Equals 3" is =3.
"and six" relates to "sum".
So when you put these together it would be 5x+6=3
Answer:
$12,000.00
Step-by-step explanation:
1 Year = 12 Months
20 Years = 12 * 20 = 240 Months
$50.00 a month for 20 years will be $50.00 * 240 months = $12,000.00.
