Answer:
(3, -1)
Step-by-step explanation:
The easiest way to solve this system of equations is by elimination:
3x + y = 8
2x - y = 7
Add the two equations together:
(3x + 2x) + (y - y) = (8 + 7)
5x = 15
x = 3
Substitute x back into the equation:
2x - y = 7
2(3) - y = 7
6 - y = 7
- y = 1
y = -1
The fourth option, (3, -1)
2/5 will be shaded in the original how I got it s that you make a rectangle and make fifths inside and shade in 3/5 of that and see what matches up on the top.
The answer is 2004 because thats when MLK was first brought to my attention and I remember black lives matter allot
<span>"The company pays $55 a day for food and lodging and $0.45 for each mile traveled" means that if she travels
m miles and is on a trip for
x days then Rita will receive:
55x + 0.45m dollars.
Rita drove 300 miles, means that m=300. Thus </span>
55x + 0.45m becomes <span>
</span>
(dollars.)
She was reimbursed $2,335 means that
.
Part A:
.
Part B:
We are given the equation 55x+135=2,335. Subtracting 135 from both sides we have:
55x=2,335-135=2,200.
Dividing both sides by 55, we get: x=2,200/55=40.
Part C: since x represents the number of days Rita spend on this trip, and x=40, then Rita spent 40 days on this trip.
