Hi there!
So, our two equations are:
2x + 3y = 20 and
-2x + y = 4
We can see that the x's will cancel out because they're the same number, opposite signs. Then we're left with 4y = 24.
Divide 24 by 4, which is 6.
y = 6, then we plug that in to the first equation for y:
2x + 3(6) = 20
2x + 18 = 20
2x = 2
x = 1
So, she made her first mistake when adding the equations, adding 20 and 4, she somehow got 16.
The solution to the system is (1,6).
I hope I helped!
8 months. Because 8 x 8 = 64.
Hoping this helps!!!:)
Answer:
162 is 65.587044534413% of 247
rounded its 66%
Step-by-step explanation:
(7h)^3
=(7h) (7h) (7h)
=7×7×7×h×h×h
343h^3
I use that example all the time
It's 3/4
no number line provided for me, but if you find the common denominator (4), and convert 1/2 into 2/4, then adding 2/4+1/4 is easy, and equals 3/4
