Answer:
...0
Step-by-step explanation:
8 x 1.25 = 10
10 x 10 = 100
By trial and error, I got it first correctly. The granola
bars cost $1 each and the yogurt is $.50 per cup. By plugging this in to each
equation, you'll see that 12 granola bars equals $12, and 7 cups of yogurt
equals $3.50, for a total of $15.50. The second account would produce $6 +
$5.50, which equals $11.50.
Answer:
Length = 6 + 23 = 29 feet
Step-by-step explanation:
Width = x
Length = x + 23
2x + 2(x+23) = 70
2x + 2x + 46 = 70
4x = 70-46
x = 24/4
x = 6
Answer:
C
Step-by-step explanation:
To factorise the quadratic
Consider the factors of the constant term (- 39) which sum to give the coefficient of the x- term (- 10)
The factors are - 13 and + 3, since
- 13 × 3 = - 39 and - 13 + 3 = - 10, hence
x² - 10x - 39 = (x - 13)(x + 3) ← in factored form
x - 13 is a factor → C
