Let r, g and b represent red, green and blue.
r+g+b = 74
r=g-1
b=r+g
Again, r+g+b = 74. Let's substitutte r+g for b: r+g+(r+g) = 74.
Next, let's eliminate r. Use r=g-1. Then g-1 + g + g-1 + g = 74
Combining the g terms, 4g - 2 = 74 => 4g = 76 => g = 19
Recall that r=g-1
and
b=r+g
Find r. If r=g-1, and g=19, then r = 19-1=18
Find b: b = r+g = 18+19=37
So there are 37 blue candies, 18 red candies and 19 green candies.
Check: 37+18+19=74 ??? Yes.

Substituting values in equation (1)
Answer:
30 miles
Step-by-step explanation:
In this context, "per" means "divided by", so to find miles per gallon, divide miles by gallons:
(56 1/4 mi)/(1 7/8 gal) = 30 mi/gal
The vehicle can travel 30 miles per gallon of gas.
_____
My calculator divides mixed numbers directly, as many graphing calculators do. If you're working this out by hand, you can convert to improper fractions, then multiply the numerator by the inverse of the denominator.
(56 1/4)/(1 7/8) = (225/4)/(15/8)
= (225/4)·(8/15) = (225/15)·(8/4)
= 15·2 = 30
Answer:
3 cups
Step-by-step explanation:
Assumptions: How much sugar does cost sprinkle on the brownies. Cost meant Cody
Given data:
Total of 4 cups
3/4 is sprinkled onto a plate of brownies
The rest onto a plate of lemon cookies
<em>Sugar sprinkled on brownies </em>= (3/4) * 4
<em>Sugar sprinkled on brownies</em> = 3 cups.
So, the questions is 6^(-6) * 6^(-1).
Remember, whenever we are multiplying two numbers with the same base and with different exponents, we should always add the exponents and keeps the same base.
In this ,case it is, -6 and -1.
-6 + (-1) = -7
So the answer would be 6^(-7).
