Answer:
2x + 8 > -16
Step-by-step explanation:
Any time you see twice a number, it means 2x because 2x indicates you are multiplying whatever the variable is by two (also known as doubling it). Whenever you see more than, it indicates addition, so now you know to add eight to that answer. Finally, place the greater than symbol and put -16 on the other side.
Answer:
1.39
Step-by-step explanation:
100 = 12x, this finds how many hours she works total over 6 days.
so x = 8.33, so she works 8.33 hours per 6 days.
8.33 = 6x, solves for how many hours per day
x = 1.38
So she works 1.38 hours everyday.
Answer:
B: (x - 4)² = 44
Step-by-step explanation:
Start with x^2 - 8x - 10 = 18.
Simplify the constants by adding 10 to both sides: x^2 - 8x - 10 + 10 = 18 + 10.
Then x^2 - 8x = 28.
Now identify the coefficient of x. It is -8.
Take half of this, obtaining -4.
Square this result, obtaining 16.
Add 16, and then subtract 16, to x^2 - 8x:
x^2 - 8x + 16 - 16 = 28.
Add 16 to both sides:
x^2 - 8x + 16 = 28 + 16 = 44
Rewrite x^2 - 8x + 16 as (x - 4)², so that we have:
(x - 4)² = 44. This is in the form (x - p)² = 44, and matches Answer B.
Note: Please use " ^ " to indicate exponentiation: (x - 4)^2 = 44
Answer:
x = -24/5
Step-by-step explanation:
2x – 3 + 3x = – 27
Combine like terms
5x -3 = -27
Add 3 to each side
5x-3+3 = -27+3
5x = -24
Divide each side by 5
5x/5 = -24/5
x = -24/5
