Given data
Profit from apple= $0.4
Profit from banana= $0.4
Let the number of Apples sold be x, and the number of bananas sold be y
and the total profit be P
Hence the expression for the total profit is given as

A jar contains sugar. The jar and the sugar have a total weight of 850 g. Anna uses 2/3 of the sugar. The jar and the sugar now have a total weight of 530 g. Work out the weight of the jar.
Answer:
[tex]J = 370g[/tex]
Step-by-step explanation:
Given
Represent the weight of the Jar with J and the sugar with S
Initially, we have:
[tex]J + S = 850g[/tex]
After 2/3 of sugar is removed we have:
[tex]J + S -\frac{2}{3}S= 530g[/tex]
Required
Determine the weight of the jar
[tex]J + S = 850g[/tex] --- (1)
[tex]J + S -\frac{2}{3}S= 530g[/tex] --- (2)
Simplify (2)
[tex]J + S -\frac{2S}{3}= 530g[/tex]
Take LCM
[tex]J + \frac{3S - 2S}{3}= 530g[/tex]
[tex]J + \frac{S}{3}= 530g[/tex]
Make S the subject in (1)
[tex]J + S = 850g[/tex]
[tex]S = 850g - J[/tex]
Substitute 850g - J for S in [tex]J + \frac{S}{3}= 530g[/tex]
[tex]J + \frac{850g - J}{3}= 530g[/tex]
Multiply through by 3
[tex]3 * J + 3*\frac{850g - J}{3}= 530g * 3[/tex]
[tex]3J + 850g - J= 1590g[/tex]
Collect Like Terms
[tex]3J - J= 1590g-850g[/tex]
[tex]2J= 740g[/tex]
Make J the subject
[tex]J = \frac{1}{2} * 740g[/tex]
[tex]J = 370g[/tex]
The jar weighs 370g

David is solving a system of linear equations by graphing. First he graphed both equations on a coordinate plane . What should be his next step in solving the system of linear equations
Answer:
look for coordinates of their intersection
Step-by-step explanation:
When looking at a system of equations you want an answer that satisfies both equations. This is no different on a graph. On the graph, you want a point that satisfies both lines. This point would be their intersection.
You and 3 friends are going to the fair. You have a coupon that will save your group $20. If the total bill to get into the fair was $100, how much does one regular priced ticket to the fair cost?
Equation:
Answer:
Answer:
one regular ticket costs $30
Step-by-step explanation:
The total number of people = 4
Without the $20 coupon, the total cost would have been =100+20 = $120
Assume the price of one regular ticket is x;
4x = 120
Divide both sides by 4 to solve for x
x = 120/4
x = 30
Therefore, one regular ticket costs $30
Answer:
$30
Step-by-step explanation:
Since you pay 100 after discount, you add the 20 dollar discount to the 100 ($120)
Then since there are 4 of you in total, (you+ 3 friends), you divide by 4.
And Voila, your answer is $30 per person.
Hope this helps :)

Step-by-step explanation:
6.72 x 10^5= 6.72 x 10^(4+1)= 6.72 x 10^1 ×10^4
= 67.2 x 10^4
(67.2 x 10^4)+ (3.2 x 10^4)

Which model shows ^3√64 = 4 ?
Answer:
if we carefully observe, left-bottom model contains 4 units on each side of the cube.
Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].
The correct model is attached below.
Step-by-step explanation:
Given the expression
[tex]\sqrt[3]{64}=4[/tex]
Cubing both sides
64 = 4³
Thus, the cube will have 4 units on each side.
Now, if we carefully observe, left-bottom model contains 4 units on each side of the cube.
Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].
The correct model is attached below.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Four numbers:
-2, 4, -9, 7
We see that,
The sum of the four numbers is 0.
-2 + 4 + (-9) + 7
= -11 + 11
= 0
None of the numbers are opposite.
Thus,
The four numbers are -2, 4, -9, and 7.

Andy’s dog weighs 27 pounds, which is 3/4 the weight of Seher’s dog. How many pounds does Seher’s dog weigh?
Answer:
20.25 lbs
Step-by-step explanation:
Multiply 27 by 3/4 or .75 to equal 20.25.
Answer:
36 pounds.
Step-by-step explanation:
Suppose Seher's dog weigh x pounds, here is an equation:
27=[tex]\frac{3}{4}[/tex]x
multiply 4 on both sides and dividing 3 on both sides, we get:
36=x
we flip this around:
x=36
So, Seher's dog weighs 36 pounds.
