Answer:
1/2x>=33
Step-by-step explanation:
We can write this as an equation: [(x - 9) + (x - 9)] + (x + x) = 70
Steps to solve:
[(x - 9) + (x - 9)] + (x + x) = 70
Combine like terms:
(x + x + x + x) + (-9 - 9) = 70
Simplify.
4x - 18 = 70
Add 18 to both sides.
4x - 18 + 18 = 70 + 18
Simplify.
4x = 88
Divide 4 to both sides.
4x/4 = 88/4
Simplify.
x = 22

Answer:
1, 2, 3, 5, 6, 10, 15, 30
Step-by-step explanation:
If you are asking for all the factors
80 is the median, heres an easy way to look at it
74, 77,78,78,79,79,80,80,80,80,80,81,81,82,82,82,82,82
write that down and cross out one at a time on each end until you get to the last one, or two in the middle. If it comes down to 2 numbers add and divide by 2.
Answer:
x = - 
Step-by-step explanation:
Given
9x² + 30x + 25 = 0 ← left side is a perfect square
(3x + 5)² = 0, thus
3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = -
solution is x = - with multiplicity 2
