0.275
275 is in the thousandths place, therefore the numerator will be 275 and the denominator will be 1000.
275/1000 is our new fraction, but we must simplify. 5 goes into both numbers, so 275 divided by 5 is 55 and 1000 divided by 5 is 200. 55/200 is our new fraction. We keep dividing by 5 until you can't anymore.
So when that's done the simplified fraction is 11/40.
Hey there! :)
Answer:
A. 23.
Step-by-step explanation:
Given:
5 + 2(x + 7)² for x = -4
Substitute in -4 for x in the equation:
5 + 2((-4) + 7)²
5 + 2(3)²
5 + 2(9)
5 + 18 = 23.
Therefore, the correct answer is A. 23.
Answer:
- single term
- sum of 4 terms, some of which can be expanded further
Step-by-step explanation:
1. 3x
This is a single term with one variable of the first degree.

2. 4x + 9(2x + 1) x² + 6(-2x + 1) - 3(7 + x?)
This is a sum of 4 terms, some of which can be expanded:
- 4x
- 9(2x+1)x^2 ⇒ 18x^3 +9x^2
- 6(-2x +1) ⇒ -12x +6
- -3(7+x?) ⇒ -3x? -21
The expression can be simplified by combining like terms.
Answer:
A. 20, 10 and 5
Step-by-step explanation:
Because 5 x 2 = 10, 10 x 2 = 20, 20 + 10 + 5 = 35.
