The answer is the distributive property because it states that if you have a number multiplied by a quantity, you can just multiply that number by each of the terms in the quantity. For example, a(x+y)=ax+ay.

Answer:
127 hamburgers
Step-by-step explanation:
let c = # of cheeseburgers
let h = # of hamburgers
c = 2h (The number of cheeseburgers sold was two times the number
of hamburgers sold.)
h + c = 381 (combined total)
h + 2h = 381
3h = 381
h = 127

Answer:
Step-by-step explanation:
Divide each term by - 1/4 first
- -1/2x ÷ (- 1/4) = 1/2x × 4 = 2x
- -5/4y ÷ (- 1/4) = 5/4y × 4 = 5y
Now facor out - 1/4
- - 1/2x - 5/4y =
- - 1/4 (2x + 5y)
Answer:
The sample size is 183.
Step-by-step explanation:
Given:
σ = $1050, ppulatin standard deviation
99% confidence interval
Accuracy = +/- $200
The accuracy is given by
z*(σ/√n)
where
z* = 2.576 for 99% confidence level (from tables)
n = sample size
Therefore
2.576(1050/√n) = 200
√n = (2.576*1050)/200 = 13.524
n = 182.9
<em>The sample size is 183</em>
