i)
2(x+2)=7
2x+4=7
2x=7-4
2x=3
x=3/2
ii)3x + y =8 , y=x
3x + x = 8
4x = 8
x = 2
Answer:
x = 2
Step-by-step explanation:
2(x+2)=7
2x+4=7
2x=7-4
2x=3
x=3/2
3x + y =8 , y=x
3x + x = 8
4x = 8
x = 2

4x = y
2x^2 - y = 0
2x^2 - 4x = 0
2x(x - 2) = 0
2x = 0 or x - 2 = 0
x = 0 or x = 2
y = 4(0) or y = 4(2)
y = 0 or y = 8
Therefore, solution set is {(0, 0), (2, 8)}

Complementary angles are angles where the sum equals 90°. So all you have to do is 90-32 and you get 58.
Answer:
what are the color of the marbles that are not red?
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
We can use the pythagorean theorem giving us:
a^2+b^2=c^2
(6sqr2)^2 + (6sqr2)^2 = c^2
72+72=c^2
144=c^2
12=c
Answer:
3/4 x 5 = 15/20
3/5 x 4 = 12/20
15/20 + 12/20 = 27/20
Hope this helps!
