Calvin has $8.80 in pennies and nickels. If there are twice as many nickels as pennies, how many pennies does Calvin have? How m
Ray Of Light [21]

Let X = the number of pennies.

The number of nickels would be 2X

A penny is 0.01 and a nickel is 0.05

Now you have:

0.01x + 2(0.05x) = 8.80

Simplify:

0.01x + 0.10x = 8.80

Combine like terms:

0.11x = 8.80

Divide both sides by 0.11:

x = 8.80 / 0.11

x = 80

Pennies = X = 80 total pennies.

Nickels = 2x = 2 *80 = 160 nickels.

Solve by the linear combination method (with or without multiplication)
AURORKA [14]
6x-2y=2
-3x+4y=5

2(-3x)+2(4y)=2(5)
-6x+8y=10

6x-2y=2
-6x+8y=10
6y=12
y=2

6x-2(2)=2
6x-4=2
6x=6
x=1

y=2 and x=1

Alexxx [7]

Answer:

A. 25 girls

Step-by-step explanation:

Suppose the number of boys is b and the number of girls is g.

We know that the ratio of boys to girls is 6 to 5, so we can write this as:

b:g = 6:5   or    b/g = 6/5

We also know that there are 30 boys, so b = 30. We plug this value of 30 in for b in our ratio. Now, we just have a proportion with one variable g:

\frac{b}{g} =\frac{6}{5}  ⇒  \frac{30}{g} =\frac{6}{5}

Cross-multiplying, we get:

6 * g = 30 * 5 = 150

g = 150/6 = 25

Thus, there are 25 girls, so the answer is A.

Hope this helps!
