Answer:
-2073.5
Step-by-step explanation:
We will have to solve this question using step by step procedure
So let's solve
(21/7+316)(5/2+4-13)
(21/7+316)
Lcm is 7
21+2212/7
2233/7
(5/2+4-13)
Lcm is 2.
5+8-26/2
13-26/2
-13/2
Back to the question
(2233/7)(-13/2)
-29029/14
-2073.5
Answer:
see below
Step-by-step explanation:
4 quarts for 12 square yards means the constant of proportionality is 3 square yards per quart.
y = 3x
Fill in x=5 to find the square yards for 5 quarts:
y = 3·5 = 15
Mona can clean 15 square yards with 5 quarts.

Step-by-step explanation:Renee Descartes was the person that invented slope of a line
<span>6n+12=2n+36
We move all terms to the left:
6n+12-(2n+36)=0
We get rid of parentheses
6n-2n-36+12=0
We add all the numbers together, and all the variables
4n-24=0
We move all terms containing n to the left, all other terms to the right
4n=24
n=24/4
n=6</span>
The total bill for the Cunningham family was $29.26.
Step-by-step explanation:
Step 1; First we total up the cost of the food alone. Mr. Cunningham spent $7.50, Mrs. Cunningham spent $6.25, the 2 children spent $4.99 each which equals $9.98 for both. So the total of the food alone was $23.73.
Step 2; The sales tax rate was 7.25% of the $23.73. So we multiply 0.0725 (7.25%) with the $23.73 which equals $1.72. So the total bill was for $23.73 + $1.72 which equals $25.45.
Step 3; The Cunningham family left a 15% tip. This was 15% of the toal bill which was $25.45. So we multiply 0.15 (15%) with $25.45 which equals $3.81. So the total bill was food cost + service tax + tips which is $23.73 + $1.72 + $3.81 = $29.26
