Answer:
a) For Khalil's purchase
4x + 3y = 11.67.....Equation 1
For Ronda's purchase
8x + y = 12.89......Equation 2
b) A can of soup = x = $2.09
Loaf of bread = y = $1.35
Step-by-step explanation:
A grocery store is offering a sale on bread and soup. Khalil buys four cans of soup and three
loaves of bread for $11.67. Ronda buys eight cans of soup and one loaf of bread for $12.89.
Homework Help!
Let us represent:
a can of soup = x
Loaf of bread = y
a. Write equations for both Khalil's and Ronda's purchases.
For Khalil's purchase
= Khalil buys four cans of soup and three loaves of bread for $11.67.
4x + 3y = 11.67.....Equation 1
Ronda buys eight cans of soup and one loaf of bread for $12.89.
8x + y = 12.89......Equation 2
b. Solve the system to find the price of one can of soup and the price of one loaf of bread.
We have:
4x + 3y = 11.67.....Equation 1
8x + y = 12.89......Equation 2
y = 12.89 - 8x
We substitute 12.89 - 8x for y in Equation 1
4x + 3(12.89 - 8x) = 11.67
4x + 38.67 - 24x = 11.67
38.67 - 11.67 = 24x - 4x
27 = 20x
x = 27/20
x = 1.35
y = 12.89 - 8x
y = 12.89 - 8 × 1.35
y = 12.89 - 10.8
y = 2.09
Therefore,
Solving for y
a can of soup = x = $2.09
Loaf of bread = y = $1.35
A rectangular prism has a volume of 729 ft3. The length width and height are all the same. What is the is the length of each side of the prism?
Answer:
9 ft
Step-by-step explanation:
As length, width and height are same, then it is a square prism / cube
Volume of prism = 729 ft³
side³ = 729
side³ = 9³
Side = 9 ft

Answer:
20°
Step-by-step explanation:
ok so if 40 degrees is on one side its also on the side parallel from it
a straight line = 180 degrees
so 180 - 40 = 140
so 7x =140
we now divide 7 on both sides and get x=20 because the 7 cancels out
180 -40 =140
7x = 140
7x/7 =140/7
x=20

A number line is the representation of numbers in real order.
The difference between the consecutive numbers in a number line is always positive.
The length AB is 29.
AB = 29 is our answer.
What is a number line?It is the representation of numbers in real order.
The difference between the consecutive numbers in a number line is always positive.
We have,
A is at point 16.
B is at point 45.
Now,
The distance between A and B.
= B - A
= 45 - 16

Answer:
(-2, -4)
Step-by-step explanation:
Given the coordinate (x, y), if rotated 90degrees, counterclockwise, the resulting coordinate will be (-y, x)
For the coordinate (-4, 2)
When rotated 0 degrees counterclockwise, the resulting coordinate will be at (-2, -4)
Note that the coordinates were switched and the x negated

The value of the expression 21 ÷ 3 + (8 - 2 ÷ 2) is 14.
To simplify the expression 21 ÷ 3 + (8 - 2 ÷ 2).
we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.
The expression inside the parentheses should be solved first.
8 - 2 ÷ 2.
First, divide 2 by 2, which equals 1.
Then, subtract 1 from 8: 8 - 1 = 7.
Now, we have 21 ÷ 3 + 7.
Divide 21 by 3, which equals 7.
Finally, add 7 + 7, which equals 14.
Therefore, the simplified expression 21 ÷ 3 + (8 - 2 ÷ 2) equals 14.

You can buy a 6 back of Gatorade for $4.99 or you can buy 1 for $0.89. Which is
the better buy?
6 for $4.99
1 for $0.89
Answer: 6 for $4.99
Step-by-step explanation: You would be better off buying 6 for $4.99 because the unit rate of each bottle is cheaper. You can find the unit rate by dividing 4.99 by 6 which equals .83
If you were to buy 6 for .89 you would end up spending $5.34.

A 30 pack of Flaming Hot Cheetos cost $10.82 at
Costco. A 50 pack of Flaming Hot Cheetos cost
$17.25.
a) Which is the better buy? (You are trying to
compare the cost of a 30 pack and 50 pack of
chips. This is not possible without finding
the unit rate.)
b) What is the difference between the unit
prices? (You need to use the information
from part a to answer this question.)
Answer:
50 pack
[tex]\$0.01[/tex]
Step-by-step explanation:
Number of packs at Costco = 30
Cost of 30 packs at Costco = $10.82
Number of packs at the other place = 50
Cost of 50 packs = $17.25
Cost of one pack when 30 packs are bought
[tex]\dfrac{10.82}{30}=\$0.36[/tex]
Cost of one pack when 50 packs are bought
[tex]\dfrac{17.25}{50}=\$0.35[/tex]
It is better to buy the 50 pack.
Difference in the unit prices = [tex]0.36-0.35=\$0.01[/tex].
