Answer:
they have the same slopes
Step-by-step explanation:
lines that have the same slope never touch therefore they are parallel.
hence the answer is A
Answer:
21
Step-by-step explanation:
Answer:
x= 99
Step-by-step explanation:
first we open brackets
6x+36=7x-63
transpose
6x-7x= -63-36
-x=-99
the signs cancel each other so
x= 99
54 because if x+y=82 and x-y=26 add 26 and 82 is 108 the divide it by 2 your answer is 54
Answer:
Dryer cost $475; Washer cost $382
Step-by-step explanation:
For this problem, we will simply set up a system of equations to find the value of each the washer (variable x) and the dryer (variable y).
We are given the washer and dryer cost $857 together.
x + y = 857
We are also given that the washer cost $93 less than the dryer.
x = y - 93
So to find the cost of the dryer, we simply need to find the value of y.
x + y = 857
x = y - 93
( y - 93 ) + y = 857
2y - 93 = 857
2y = 950
y = 475
So now we have the value of the dry to be $475. We can check this by simply plugging in the value and see if it makes sense.
x + y = 857
x + 475 = 857
x = 382
And check this value:
x = y - 93
382 ?= 475 - 93
382 == 382
Therefore, we have found the values of both the washer and the dryer.
Cheers.
