Answer:
Carrie and Joan have 80 nickels and 40 dimes, respectively, and each one has an amount of money of 4 US dollars.
Step-by-step explanation:
Let be 
and 
the amounts of nickels and dimes that Carrie and Joan have, as 
the total amount of money that both Carrie and Joan have. A nickel is a five cent coin and a dime is a ten cent coin.
The following equations are constructed after a careful reading on statement:
Carrie's amount of money:
(Eq. 1)
Joan's amount of money:
(Eq. 2)
Relation between amounts of coins:
(Eq. 3)
First we eliminate by equalizing (Eq. 1) and (Eq. 2):
Then, we reduce the resulting formula by (Eq. 3):
And rest of variable are now determined:
Carrie and Joan have 80 nickels and 40 dimes, respectively, and each one has an amount of money of 4 US dollars.
For the restaurant to make 20 gallons of a lemonade mixture that is 10% sugar, they need 12 gallons of the 12% lemonade and 8 gallons of the 7% lemonade. The correct answer is A.
You would do for pens
22 x 1.15 =25.30
And for markets
15 x 2.05 = 30.75
And since you are trying to find how much he spent in all you would add the two sums
25.30 + 30.75 = 56.05
X=1/2
Alternative: 0.5 or 2^-1
Allen's claim that we do not have enough information to solve for angle 1 is incorrect
<h3>How to calculate the measure of angle 1</h3>
Given that:
Angle 2 = 110 degrees
Angle 1 and angle 2, are the only angles on the straight line.
So, we have:
Substitute 110 for angle 2
Subtract 110 from both sides
The measure of angle 1 is 70 degrees.
So, we can conclude that Allen's claim is incorrect
