Answer:
x=1 y = -1/2
(1,-1/2)
Step-by-step explanation:
7x-2y=8
5x+2y=4
I would use elimination since we have 2y in one equation and -2y in the other
7x-2y=8
5x+2y=4
--------------------
12x = 12
Divide each side by 12
12x/12 = 12/12
x =1
The substitute back into equation 2
5(1) +2y = 4
5 +2y = 4
Subtract 5
5-5+2y = 4-5
2y = -1
Divide by 2
2y/2 = -1/2
y = -1/2
Answer:
75%
Step-by-step explanation:
(94-23.5)/(94)*100=75%
Hello there,
202.366 to the nearest hundredth would be 202.37.
So what I did was I look at the 366 in the problem.
We want to round the to the nearest hundredth.
So what we would do it notice how the 66 in over 50.
The rule is if it's over 50, we round it to the nearest.
So your answer would be 202.37.
Hope this helps.

Answer:
the value of x n lengh of pq is 12.6
Given
perimeter is 62
Side 1 - 3x+5
Side 2 - x+2
Solution,
2(3x+5+x+2) = 62
4x+7 = 31
4X = 24
x = 6
Now substitute the value of x to get the sides
Side one - 3x+5 = 23cm
Side two - x+2 = 8cm
Answer- the length of the longest side is 23 cm
