Step-by-step explanation:
10 ^-3
= 1/10^3
= 1/1000.
I think it might be 2 because 20 divided by 2 there is no left over
Answer:
x = 3
Step-by-step explanation:
2x + 4 = 10
-4. -4
(2x = 6) ÷ 2
x = 3
Rewriting the equation as a quadratic equation equal to zero:
x^2 - x - 30 = 0
We need two numbers whose sum is -1 and whose product is -30. In this case, it would have to be 5 and -6. Therefore we can also write our equation in the factored form
(x + 5)(x - 6) = 0
Now we have a product of two expressions that is equal to zero, which means any x value that makes either (x + 5) or (x - 6) zero will make their product zero.
x + 5 = 0 => x = -5
x - 6 = 0 => x = 6
Therefore, our solutions are x = -5 and x = 6.
Answer: She will have to save for 8 weeks.
Step-by-step explanation:
164 = 52 + 8w
