8.
use quadratic formula
Answer:
1. x = -5
2. x = -7
3. x = 8
4. s = 8
5. h = 6
6. y > 5
7. y < 14/3
8. y > 2√5 -2
9. y < 3
10. s = 7
Step-by-step explanation:
1.
x + 7 = 2
x = 2 - 7
x = -5
2.
-5x = 35
-5x ÷ -5 = 35 ÷ -5
x = -7
3.
x - 10 = -2
x = -2 + 10
x = 8
4.
2s = 16
2s ÷ 2 = 16 ÷ 2
s = 8
5.
3h - 2 = 16
3h = 16 + 2
3h = 18
3h ÷ 3 = 18 ÷ 3
h = 6
6.
5y > 25
5y ÷ 5 > 25 ÷ 5
y > 5
7.
3y - 2 < 12
3y < 12 + 2
3y < 14
3y ÷ 3 < 14 ÷ 3
y < 14/3
8.
(search for the solution of this)
9.
y + 5 < 8
y < 8 - 5
y < 3
10.
2s + 7 > 21
2s > 21 - 7
2s > 14
2s ÷ 2 > 14 ÷ 2
s = 7
Hope this helps :)
