I think it’s subtract 2x from both sides
Answer:
(x, y) = (-1, 1)
Step-by-step explanation:
8x + y = −7
for y = 1
8x + 1 = -7
subtract 1 from boh sides
8x = -8
divide bot sides by 8
x = -1
(x, y) = (-1, 1)
Answer:
$720
$360
Step-by-step explanation:
Let the cost of couch be A and that of coffee table be B
Given couch and coffee table cost $1080
That’s
A + B = $1080
Also, the cost of couch A is 2 times the cost of coffeee table B.
That’s
A = 2B
We now have two equations
A + B = 1080
A = 2B
Now ,substitute 2B for A in the first equation .
We have
A + B = 1080
2B + B = 1080
3B = 1080
Divide both sides by 3
3B/3 = 1080/3
B = 360
The coffee table cost $360
Remember A = 2B
Therefore
A = 2 x $360
A = $720
The couch cost $720 while the coffee table cost $360
Answer:
Okay the question is a little unclear, but if he's only doing english, science and history the answer should be <u> 17/40</u>
Step-by-step explanation:
1/5=8/40
3/8=15/40
8/40+15/40=23/40
40/40-23/40=17/40
Answer:
|3-8|-(12/3+1)2
=|-5|-(4+1)2
=5-5x2
=5-10
=-5
You said simplify, but it can be solve.
