Answer:
7.5
Step-by-step explanation:
8x÷4=12÷4
2x=3
x=3/2=1.5
2y+10=22
2y=12
y=6
1.5+6=7.5=7½
I think the answer is 9 , not sure but I really think so
4x^2-22x+30
=2(2x^2 - 11x + 15)
=2(2x^2 -6x -5x +15)
= 2 { 2x(x-3) - 5(x-3) }
= 2 (x-3) (2x - 5)
7
-54 / 9 * -7 / 6
Multiply and divide from left to right
-6 * -7/6
42 / 6
