45 = 15% × n
15% =
45 = 0.15n
0.15 and 0.15 cancels out
300 = n
15% of 300 is 45
45 is 155 of 300
15% × x = 45
x = 45 ÷ 15%
x = 45 ÷ 15/100
x = 45 × 100/15
x = 4500/15
x = 300
Check:
15% × 300
= 15/100 × 300
= 15 × 3
= 45
45 is 15% of 300.

What is Darius’s error?
Answers
Answer: he needs to finish factoring the 4s.
Step-by-step explanation:
4x15 is 60, so that is right, 3x5 is 15, so that’s is right, 2x2 is 4, so that is right, but he didn’t finish factoring. 1x1 is 2, so he should have 1 and 1 coming from each 2 on the tree. Hope this helps.

Answer:
The solution set is {-1, 7}
Step-by-step explanation:
Rewrite x^2-6x=7 as x^2 - 6x = 7.
Identify the coefficient of the x term; it is -6.
Halve this coeff (obtaining -3)
Square this result (obtaining 9)
Add 9 to x^2 - 6x and then subtract 9 from the result: x^2 - 6x + 9 - 9
Then we have:
x^2 - 6x + 9 - 9 = 7. Add 9 to both sides, obtaining
x^2 - 6x + 9 = 16
Rewrite x^2 - 6x + 9 as the square of a binomial: (x - 3)^2
Then we have
(x - 3)^2 = 16
Taking the square root of both sides, we get
x - 3 = ±4, so that: x = 3 + 4 = 7, and x = 3 - 4 = -1.
The solution set is {-1, 7}.
Answer:
To complete the square x^2-6x=7
We take the coefficient of X which is -6
divide it by 2 -3
square that number 9
then add it to both sides of the equation.
x^2 -6x + 9 = 16
(x -3) * (x -3) = 16
We take the square root of both sides:
a) x-3 = 4
b) x-3 = -4
Therefore, x = 7 and x = -1
