Answer: 23in squared
Step-by-step explanation:
9 plus 4 plus 10
3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50
Answer:
Step-by-step explanation:
2n - 6
a) n = 1 ; 2n - 6 = 2*1 - 6 = 2 - 6 = -4
n = 2 ; 2n - 6 = 2*2 - 6 = 4 - 6 = -2
n = 3 ; 2n - 6 = 2*3 - 6 = 6 - 6 = 0
b) n=10; 2n - 6 = 2*10 - 6 = 20 - 6 = 14
THE ANSWER IS x € (0,4)
First we separate this into two inequalities:
2x-3>-3
2x-3>-32x-3<5
Now we solve the inequalities:
2x-3>-3
2x>0
x>0
2x-3<5
2x<8
x<4
x € (0,4)
