Minh and Mikayla are selling wrapping paper for a school fund-raiser. Customers can
buy either packages of folded paper or rolls of paper. Minh sold 6 rolls of paper and 2
packages of folded paper for a total of $44. Mikayla sold 3 rolls of paper and 9 packages
of folded paper for a total of $54. How much does each roll cost? How much does each
package of folded paper cost?
Answer:
Let x=rolls of paper,y=folded paper:
6x+2y=44
3x+9y=54
-------
6x+2y=44
6x+18y=108
16y=108-44=64
y=4
x=6
Thus, a roll of paper cost $6,folded paper was $4 each

p/ 1 6/7=−4.4 help please!!!!!!!
Answer:
Sorry, I can't type well.
The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equation is given below.
p / [1 ⁶/₇] = - 4.4
Convert the mixed fraction number into a decimal number. Then we have
1 ⁶/₇ = 1 + ⁶/₇
1 ⁶/₇ = 1 + 0.857
1 ⁶/₇ = 1.857
Then the equation is rewritten as,
p / 1.857 = - 4.4
Simplify the equation, then we have
p = - 4.4 x 1.857
p = - 8.17
The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.

A. $126
B. $378
C. $1,187
D. $4,748
Answer:
C $1187

radius = 6 ft
area = πr²
= 3.14×6×6
= 113.04 ft²
paving stones is $10.5 per ft²
paving stones cost = 113.04×10.5 = 1186.92
; the nearest dollar do the paving stones cost is $1187
A farmer wants to increase the area of his rectangular pen but keep the pen a rectangular shape. He decides to add 2 1/2 feet of fencing to the width of the pen, but the length will remain 9 1/4 feet. The new area will be 108 3/4 square feet.
Which equation can be used to determine the original width, w, of the pen?
9 1/4(w+2 1/2)=108 3/4
9 1/4w+2 1/2=108 3/4
2 1/2(w+9 1/4)=108 3/4
2 1/2w+9 1/4=108 3/4
Answer:
914(w+212)=10834

Compare the values of each 7 in the number 771,548. Can you please tell the the step by step explanation? Thanks!
Answer:
700,000 >70,000
Step-by-step explanation:
To break it down:
the value of each number is the following:
first 7: 700,000 , second 7: 70,000, 1: 1000, 5: 500, 4: 40, 8:8
Since we find the values of each seven we know compare
That is how we get to 700,00>70,000

Courtney has $21.50 to buy a gift for her brother. She found a stuffed animal that costs $19.65. With 10.1% sales tax added on, what is the sales tax? What is the total cost of the stuffed animal with tax included? Will Courtney have enough money to buy the gift?
The sales tax is: $_________
The total cost is: $_________
Is it enough money?
Answer:
Sales tax: 1.98465 which in this case is $1.98 (take note that you can round and it would be $2)
The total cost: $21.63 so no, Courtney cant buy the stuffed animal :(
Step-by-step explanation:
You can find the sales tax by dividing 10.1 by 100 to get 1.984...then rounding that number to get $1.98 since we are working with money in this problem then we have to find the total cost by adding our sales tax ($1.98) to our original cost ($19.65) to get our FINAL answer of $21.63

Solve this addition question by substituting numbers for the given letters to find the value of START. Each letter represents a unique digit.
JOAN+CAN=START
Solved the given question by addition rules and the value of START is 10430.
Given-
The given problem is from the alphabetical puzzle. In the given problem the equation given is,
JOHN + CAN = START.
It can be written as,
J O H N
+ C A N
__________
S T A R T
__________
S must be 1, because, even if we assume all the missing digit are 9 ( the largest possible value), the sum will be smaller than than 10999 or equal to the 10998.Similarly the value of T must be 0 because, even if we assume all the missing digit are 9 ( the largest possible value), the sum will be smaller than than 10999 or equal to the 10998.
Now as the T is two times in the solution of addition, and the value of T is 0 as we found. But T is the addition of N and N. Hence N must be 5 to make the addition 10 for the 0 value of the T.
N
+ N
____
1 0
____
J must be 9 with carried 1 to make the T 0.
A must be more than 10 to have a carry on J. A can not 1 as S has 1 digit. 2 and 3 disturbs the equation. Thus a must be 4. and for this o and c must be 6 and 7.
If a is 4 than the H and R must be 8 and 3.
The sum will look like,
9 6 8 5
+ 7 4 5
________
1 0 4 3 0
_________
Hence, solved the given question by addition rules and the value of START is 10430.

A transportation engineer wants to determine the number of vehicles that drive through an intersection on a given day. The following table shows the total number of vehicles that drove through the intersection over a 10-hour period.
The transportation engineer determines that the linear function that best models the data is, y = -16.7333 + 52.7515x where y represents the total number of vehicles that drove through the intersection and x represents the number of hours. The following graph shows the residuals for this function.
Answer:
510.7817 or 511
explanation:
First you’re going to have to substitute 10 in for x, so
Y= 52.7515(10) -16.7333
Y=527.515-16.7333
Then subtract
Y=510.7817
