Suppose you want to make a certain kind of tropical punch using bananas,
oranges, and papayas. This is what you know.
You know the recipe takes seven pieces of fruit.
You don't know how many of each to put in the punch, but you know that
there are twice as many oranges as bananas.
You know that the seven pieces of fruit cost $5.25, where bananas cost $.50
each, oranges cost $.75 each, and papayas cost $1.25 each.
How many pieces of each type of fruit do you need to make the tropical punch?
Answer: 4 oranges, 2 bananas, and 1 papaya
Step-by-step explanation:
because there are twice as many oranges as bananas and 7 total fruit so 4 is the max amount of oranges you can have which leaves 2 bananas and 1 left over which is the papaya. Then to check work plug in the amount of fruit times their price which totals $5.25.
Lines c and d are perpendicular. The equation of line c is y=−12x+1. What is the equation of line d?
Answer:
y = 1/12x + b
Step-by-step explanation:
So lines that are perpendicular have a negative reciprocal slope.
If line c has a slope of -12, then line d has a slope of 1/12
So y = 1/12x + b would be perpendicular to c, where b is a constant
b.

Question 6 :
Janelle sells sandwiches She spends
$270 per sandwich on Ingredients and
then adds a 110% markup. What is the
selling price of one sandwich?
Answer:
$5.67
Step-by-step explanation:
$5.67
Markup refers to the amount added to the cost price to cover overheads and profit. So for example a 50% markup on a $10 product would mean adding 50% of $10 onto the sale price. As fractions can be written as decimals (50% = 0.5) and we are adding on the amount of markup to the initial cost we can also phrase this as 10 x 1.5 = 15
For your question, the markup would become 1.1 and the initial cost is 2.7, remembering we must add 1 to the markup to cover the initial cost
2.7 x 2.1 = 5.67

At Bo's Bagels, 15 bagels cost $12.75. At
Murray's Bagels, 6 bagels cost $5.40.
Which store, Bo's or Murray's, offers a better bargain on
bagels? In other words, which place has the lower cost
bagels?
Use numbers, pictures, a diagram and/or words to
support your reasoning.
Answer:
Bo's Bagels
Step-by-step explanation: 12.75 divided by 15 is 0.85, meaning each bagel costs 85 cents. 5.40 divided by 6 is 0.90, meaning that each bagel costs 90 cents. 85 > 90.
Evaluate: 4 + 8 / 2 • (6 - 3)
Answer:
4 + 8 / 2 · (6 - 3) = 16
Step-by-step explanation:
Use PEMDAS
Parenthesis first
6 - 3 = 3
the equation is now 4 + 8 / 2 · 3
divide 8 and 2 = 4
4 + 4 · 3
multiply 4 and 3 = 12
4 + 12
add 4 and 12 = 16

Julie deposited $500 into an account that earned 10% compound interest over 5 years. What is the account value earned after 5 years?
Answer:
$821
Step-by-step explanation:
A = p (1 + r/n)^nt
Where,
A = future value
P = principal = $500
r = interest rate = 10% = 0.1
n = number of periods = 12
t = time = 5 years
A = p (1 + r/n)^nt
= 500 (1 + 0.1/12)^12*5
= 500 (1 + 0.0083)^60
= 500 (1.0083)^60
= 500 (1.6420)
= 821
A = $821

The scatter plot shows a scuba diver’s depth in the ocean. The equation of the trend line shown is y = –3.29x – 10.
Predict what the diver’s depth will be after 30 minutes.
____feet below sea level
Answer:
It's not given a scatter plot not the characteristics of the variables, but it can be safely assumed as shown below
Answer:
The diver's depth will be -42.9 after 30 minutes
Step-by-step explanation:
The equation of the trend (or best fit line) for the scuba diver's depth in the ocean is:
y = -3.29x - 10
Where y is the diver's depth and x is the time in minutes.
To predict the diver's depth at x=30 minutes, substitute in the equation:
y = -3.29(10) - 10
y = -32.9 - 10
y = -42.9
Since no units are provided for y, the answer is:
The diver's depth will be -42.9 after 30 minutes

Step-by-step explanation:
The images is where I showed all the work
The solution is given below.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
here, we have,
One-Step Equations:
Number one: x + 6 = 8
Solve: To begin, you must subtract 6 on both sides to get x by itself.
x = 8 When you subtract 6 on both sides, you get x = 8 which is your answer.
This is a one-step equation, meaning it only took us a single step in order to solve this equation.
Number two: x - 5 = 15
Solve: To solve this one-step equation, first, start off by adding 5 on both sides.
Since it's only one step, your answer will be x = 20. All we had to do was add 5 to isolate the variable.
Two equations that contain fractions:
Number one: x - 1/2 = 2/4
Solve: x - 1/2 = 2/4
To begin, we have to add 1/2 to get x by itself. Since 2/4 and 1/2 don't have common denominators, all we have to do is multiply 1/2 by 2/2 to get a common denominator of 4. 1/2 x 2/2 is equal to 2/4. 2/4 + 2/4 is 4/4 which is equal to 1. Your answer is x = 1.
Number two: x + 3/4 = 2/4
Solve: To begin, we have to subtract 3/4 on both sides. Since 2/4 and 3/4 have a common denominator of 4, we can go ahead and subtract right away. 2/4 - 3/4 is equal to -1/4. x = -1/4.
One equation using distributive property:
Number one: 3(x + 2) = 18
Solve: To begin, we have to distribute the 3 to x and 2 (multiply). We get 3x + 6 = 18. To get x by itself, we have to first subtract 6 on both sides. We then get 3x = 12. Now, divide by 3 on both sides so that x is completely isolated, and we get x = 4.
One equation with decimals:
Number one: x + 0.25 = 0.75
Solve: To begin, we have to subtract 0.25 on both sides. When we do this, 0.75 - 0.25, we get x = .50 We can also write this as a fraction .50 is the same thing as 1/2. x = 1/2 or .50
One real-world problem:
Number one: Maria went to the store and she had 20 dollars to spend. She got a notebook for 5 dollars, and she wanted to buy pens with the rest. Each ben cost 5 dollars, how many pens can she buy in total?
Solve: We know that Maria had a total of 20 dollars in total and she already spent 5 dollars. We also know that each pen cost 5 dollars. When knowing this we can write this equation: 5x + 5 = 20. Since we don't know how many pens she's going to buy, we can just write a variable, in this case, x. Now we solve. Just like always, we need to isolate the variable. To do this, we have to first subtract 5. We then get, 5x = 15. Now, divide by 5 on both sides and we get x = 3. That means that Maria can buy a total of 3 pens.
