Answer:
D. p = 6.25h
Step-by-step explanation:
6.25 (2) = p 12.50
6.25 (4) = p 25.00
6.25 (6) = p 37.50
6.25 (8) = p 50.00
Answer:
One fifth is like you saying one fifth of something, so if you have 3 fifths of something it's just 3 times more than one fifth. so like 1/5 is 20% so 3/5 is 3 times more which is 60%
Step-by-step explanation:
Answer:
x^7 / y^4
Step-by-step explanation:
Please enclose a negative exponent inside parentheses:
x^9y^(-4)/x^2
Rewrite this in the form
numerator
----------------------
denominator
x^9 *
We get: ------------ divided by x^2
y^4
x^7
Since x^9 / x^2 = x^7, our final answer is --------
y^4
To answer the question, let x be the number of pounds of coffee worth $9. Having said that, the number of pounds of coffee worth $3 is 120 - x. The equation relating the items before and after mixing is,
(x)($9) + (120 - x)($3) = (120)($5)
The value of x is 40. Therefore, the amount of coffee worth $9 and $3 to be used are 40 and 80 pounds, respectively.
