If one pint is the same amount as 2 cups, how many cups are in 6 pints?
Numerical Answers Expected!
Answer for Blank 1:
the answer is 12 because you multiply 6x2 since 1 pint=2 cups, 6 pints would be 2 times the number of pints you are trying to find.
A package of 3 pairs of insulated socks costs $24.87. What is the unit price of the pairs of
socks?
I really need this one!!! Help please ♡︎
Answer:
Each pair of socks equals $8.29.

If you divide 24.87 by 3, you get 8.29. So each pair of socks equals $8.29.
You need a 45% alcohol solution. On hand, you have a 105 mL of a 40% alcohol mixture. You also have 80%
alcohol mixture. How much of the 80% mixture will you need to add to obtain the desired solution?
You will need
mL of the 80% solution
Submit Question
You have 105 mL of a 40% alcohol solution, which contains 0.4 • 105 mL = 42 mL of alcohol.
If you mix it with x mL of 80% solution, you end up with a (105 + x) mL solution that contains (42 + 0.8x) mL of alcohol.
In this solution, you want to have a concentration of 45%, so
((42 + 0.8x) mL) / ((105 + x) mL) = 0.45
Solve for x :
(42 + 0.8x) / (105 + x) = 0.45
(42 + 0.8x) / 0.45 = 105 + x
280/3 + 16/9 x = 105 + x
7/9 x = 35/3
x = 15
So you need 15 mL of the 80% solution.

Evaluate -3x 3y 2, if x = -2 and y = -1.
Answer:
6 + -3 + 2 =
5
6 * -3 * 2 =
-36
Step-by-step explanation:
I'm assuming they have plus sings in between, if not I'll evaluate with adding and multiplying.
Plug in the values for x and y.
-3(-2) + 3(-1) + 2
Then solve.
6 + -3 + 2 =
5
6 * -3 * 2 =
-36
solve for x if y = -10 y = 4x - 16

Graph the function f(x)=-3/5X +4
What is f(5)?
Answer:
f(x)= -3x+4
Step-by-step explanation:
so plug in 5 for x then +4 is your y-intercept and then your slope is -3/1 so you go down 3 over 1 from there and so on

10. While catching fireflies, you and a friend decide to have a competition. After m minutes, you have (4m +11) fireflies and your friend has (5m +6) fireflies
A. Write an expression in simplest form that represents the number of fireflies you and your friend caught together.
B. The competition ends after 5 minutes(m). Who has more fireflies. Explain how you know.
Answer:
Lets look at the expressions with respect to the competition parameters:
Expressions:
You(Y) =4m+11
Friend(F)=5m+6
1. The competition begins AFTER you and friend already caught some flies. This would be represented by the CONSTANT terms in each expression (in this case, 13 for you, 6 for friend).
So the number of flies caught BEFORE THE COMPETITION would be...
11+6=17 flies total
2. The competition length was "m" minutes long when flies are caught and counted. This would be represented by the VARIABLE terms in each expression (in this case, 4m for you, 5m for friend). We are not given a numeric value for the variable "m" to evaluate.
So the number of flies caught DURING THE COMPETITION (timed "m" minutes long) would be....
4m+5m=9m flies total
...and the number of flies per minute would be calculated as......
9m÷m=9 flies per min....total #flies divided by total minutes
3. If the problem asked for the total number of flies caught by you and friend, before and after the competition....
9m+17 flies total.....add like terms in each expression.
Answer:
a. 9m+17
b. You caught more fireflies
