let p= pounds of expensive $6.50 coffe
Then 140-p = pounds of $2.00 coffee
6.5p + 2(140-p) = 4.89(140)
Multiply through the parenthesis,
combine like terms... solve for p.
Then you know how many pounds of
$6.50 coffee to use.
Subtract that from 140 to get how many
pounds of $2.00 coffee the use.
Toni bought some jazz records at $4 each and some classical records at $6 each. If her purchases totaled $46,?
find all possibilities for the number of each type of record that she bought.
Answer:
1 jazz and 7 classical; 4 jazz and 5 classical; 7 jazz and 3 classical; 10 jazz and 1 classical
Step-by-step explanation:
Turn the problem into an equation with x representing the number of jazz records and y as the number of classcial records. The equation will look like this: 4x+6y=46
We can graph this equation
The possibilites are when both the x and y are positive and are whole numbers because you can't buy negative records and you can't buy fractions of records.

Question 1(Multiple Choice Worth 5 points)
(04.06A HC)
The table and the graph below each show a different relationship between the same two variables, x and y:
A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 3,180 and 4,240 and 5,300 and 6,360. On the right of this table is a graph. The x axis values are from 0 to 10 in increments of 2 for each grid line. The y axis values on the graph are from 0 to 350 in increments of 70 for each grid line. A line passing through the ordered pairs 2, 70 and 4, 140 and 6, 210 and 8, 280 is drawn.
How much more would the value of y be in the table than its value on the graph when x = 11?

!!HELP ASAP!!(03.04 MC) Solve for x: (-6/5) x -4= -46
Answer:
x = 35
Step-by-step explanation:
(-6/5) x - 4 = -46
(-6/5) x - 4 + 4 = -46 + 4
(-6/5) x = -42
5(-6/5) x = 5(-42)
-6x = -210
-6x/6 = -210/-6
x = 35

Mia and her children went into a grocery store and where they sell apples for $2 each and mangos for $1.50 each. Mia has $20 to spend and must buy no less than 9 apples and mangos altogether. If Mia decided to buy 3 mangos, determine the maximum number of apples that she could buy. If there are no possible solutions, submit an empty answer.
Answer:
The maximum amount of apples she could buy is 7
Step-by-step explanation:
3 mangos would be 4.50 dollars. Subtract that from her current amount of money (20 dollars). You would get 15.5 dollars. Then, find how many apples she can buy with 15.5 dollars. You can't buy 8 because that would be above 15.5. So do the next smallest amount, 7.

To make his special energy drink, jerome uses 8 cups of water and 3 cups of drink mix what is the ratio of drink mix to water
Answer:
3:8 or 3 to 8 depending on how you personally write it
Step-by-step explanation:
In problems like these you just need to put the numbers in the order that the question asks you in. In this case it is asking for drink mix (3) to water (8) making it 3:8.
Answer:
I saw another question like this but it was the other way like "water to drink mix" and it was 8:3 so technically and mathematically it would be 3:8

Solve 5(w-2)=-2(1.5w+5) plz and thank you
Step-by-step explanation:
5(w-2)=-2(1.5w+5)
5w-10=-3w-10
8w=0
w=O
Answer:
W=0
Step-by-step explanation:
5(w-2)=-2(1.5w+5)
5w-10= -3w-10
5w+3w=-10+10
8w=0
W=0
So the value of w is 0
Before multiplying fractions change any mixed numbers to
[A] decimals
[B] estimated numbers
[C] percent
[D] improper fractions
9514 1404 393
Answer:
[D] improper fractions
Step-by-step explanation:
The usual recommendation for doing much of anything with mixed numbers is to change them to improper fractions.
__
However, that isn't always necessary. If you're doing the arithmetic with a calculator, it can be helpful to convert them to decimal numbers.* Sometimes, you can work with mixed numbers by working with the integer and fractional parts separately.
Sometimes a simple rewrite makes working with mixed numbers easier. (That is, converting part of the integer portion to a fraction may be useful in some cases.
Example:
(29 1/3) × (1/2) = (28 4/3) × (1/2) = 14 2/3
_____
* Some calculators will do arithmetic directly with mixed numbers and/or fractions. If yours doesn't, it can be helpful to memorize the decimal equivalents of a few common fractions: 1/3, 2/3, 1/6, 1/7, 1/9, 1/11 for example. This will help you convert the decimal result back to a mixed number.

Which expression is equivalent to the expression shown below?
20 + 8y - 9y - 21
Select each correct answer.
2(10 + 4y - 7y - 19)
2(10 + 4y) - 3(3y - 7)
4(5 + 2y - 5y - 17)
4(5 + 2y) - 3(3y + 7)
-(y + 1)
-(1 - y)
y - 1
Answer:
4(5+2y)=3(3y+7) and -(y+1)
Step-by-step explanation:
You combine like terms
20-21 =-1
8y -9y = -1y
so your answer is anything that is the same as -1 - y
2(10+4y-7y-19) =2( -3y-9) = -6y-18 NO
2(10 +4y) - 3(3y-7) = 20 +8y - 9y +21 = -y +41 NO
4(5+2y-5y-17)= 4(-3y -12) = -12y -48 NO
4(5+2y) - 3(3y+7) = 20 +8y - 9y -21 = -1 = y YES
-(y+1)= -y-1 YES
-(1-y) = -1+y NO
