Answer: Marcaroni salad = 4 pounds
Potatoes salad = 3 pounds
Step-by-step explanation:
From the question,
5m + 6p = 38 ......... i
m + p = 7 .......... ii
Multiply equation i by 1
Multiply equation ii by 5
5m + 6p = 38 ....... iii
5m + 5p = 35 ....... iv
Subtract equation iv from iii
p = 3
Since m+p = 7
Therefore, m + 3 = 7
m = 7-3
m = 4
Marcaroni salad = 4 pounds
Potatoes salad = 3 pounds

Chloe is replacing three different sections of her of the fence in her backyard she needs fencing and length of 13 yards for 17-year-olds in 20 yards how much fencing does she need in feet
Answer:
150 feet
Step-by-step explanation:
Here is the complete question
Chloe is replacing three different sections of her of the fence in her backyard she needs fencing and length of 13 yards, 17-yards and 20 yards. How much fencing does she need in feet
Solution
To find the total number of fencing Chloe needs in feet, we first add up the amount she needs in yards and then convert it to feet. Since she needs fencing and length of 13 yards, 17-yards and 20 yards, the total length of fencing she needs in feet is L = 13yards + 17 yards + 20 yards = 50 yards.
We now convert 50 yards to feet, Since 1 yards = 3 feet, 50 yards = 50 × 1 yard = 50 × 3 feet = 150 feet.
So Chloe needs 150 feet of fencing.
A company charges $150 deposit plus $25 per hour to rent a moving trailer. If the total cost is y and the number of hours the moving trailer is rented is x, then the equation to determine the total cost is y = 25x + 150. What is the independent variable and the dependent variable?
Answer:
The number of hours is the independent variables and the total cost is the dependent variable.
Step-by-step explanation:
From statement we get a linear function for modelling costs as a function of the number of hours rented. The standard form of the linear function is:
[tex]y = m\cdot x + b[/tex] (Eq. 1)
Where:
[tex]x[/tex] - Independent variable, measured in hours.
[tex]y[/tex] - Dependent variable, measured in US dollars.
[tex]m[/tex] - Slope, measured in US dollars per hour.
[tex]b[/tex] - y-Intercept, measured in US dollars.
Hence, the number of hours is the independent variables and the total cost is the dependent variable.

a. 27m + 13v
b. 11m - 3v
c. 25m +3v
d. 11m + 3v
Answer:
B 11m-3v
Step-by-step explanation:
You have to add like terms
18m-7m is 11m
-9v + 6v is -3v
When put into an expression, you get 11m-3v, which is choice B

Geometry!! Need help
Answer:
90 Degrees
Step-by-step explanation:
Answer:
90° will be the measure,
Step-by-step explanation:
If the angles are congruent, it means that they are same, to find them out, we can be using a simple equation,
Let the angles be x,
x + x = 180° (Because, both the angles are equal as they are congruent)
=> 2x = 180°
=> x =( 180 / 2 )°
=> x = 90°

The concession stand at a ballpark makes $0.43 profit from each hot dog sold. It also makes a profit of $0.65 from each pretzel sold and $1.31 from each drink sold. Which expression represents the total profit, in dollars, that the stand will make on a day when they sell h hot dogs, p pretzels, and d drinks? 2.39 (h + p + d) 0.43 h + 0.65 p + 1.31 d (0.43 h) (0.65 p) (1.31 d) (0.43 + h) (0.65 + p) (1.31 + d)
Answer: 0.43h + 0.65p + 1.31d
Step-by-step explanation:
Profit made from each hotdog sold = $0.43
Profit made from each pretzel sold = $0.65
Profit made from each drink sold = $1.31
Number of hotdogs sold = h
Number of pretzels sold = p
Number of drinks sold = d
Total profit made will then be the profit for each multiplied by the number of things sold. This will be:
= ($0.43 × h)+($0.65 × p)+($1.31 × d)
= 0.43h + 0.65p + 1.31d

How do I do this step by step
Answer:
-1
Step-by-step explanation:
1. You would get rid of the denominator -> Which would be 2
2. You would then multiply both sides by 2
This gets you: 2x + 22 = 20
3. You then would combine like terms -> Subtract the 22 to the side of the 20
This would get you the value of 2x = -2
4. Solve for X which gets you -1

During summer vacation, Juan traveled a total distance of 900 miles. His trip took 12 hours. What was the average speed during the trip in miles per hour (mph)? Show your work for full credit!
Answer:
75 miles per hour
Step-by-step explanation:
In order to find the answer, you have to use the formula to calculate the speed:
s=d/t
s=speed
d=distance traveled= 900 miles
t=time elapsed= 12 hours
Now, you can replace the values in the formula:
s=900 miles/ 12 hours
s=75 miles per hour
According to this, the answer is that the average speed during the trip was 75 miles per hour.

. Krista went shopping for jeans. She found a great pair for $59. She found a second pair that was pretty nice and cost only $28. About how much less would Krista spend if she bought the second pair of jeans? $20 less $40 less $30 less $80 less
Answer: Krista would spend $31 less if she bought the second pair.
Step-by-step explanation:
Given: Price of first pair of jeans = $59
Price of second pair of jeans = $28
If Krista bought second pair of jeans ( which costs $28) instead of first pair of jeans ( which costs $59), the she should pay $59-$28 = $31 less.
Hence, Krista would spend $31 less if she bought the second pair.

Answer:
C is true
Step-by-step explanation:
The true statement about the diagram is,
⇒ m ∠1 + m ∠2 = 180°
Since, An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Here, We have to given that;
The diagram of the angles are shown.
Hence, We get by diagram;
Two angles 1 and 2 are linear pair angles.
Hence, We get by definition of straight line is,

There are 36 boys on a school bus. If 60% of the students on the bus are girls, how many total
students are there? Use a proportion to solve.
Answer:
54
Step-by-step explanation:
First, we can discover that 40% of the class are boys
100-60=40
Second, we need to work out what ten per cent of the class is, which we get by dividing 36 by 4:
36÷4=9
9 is equal to ten per cent.
Then, we multiply this by 6 because 10×6=60, which is the percentage of girls in the class.
9×6=54
Therefore, we have 54 girls on the bus

are natural numbers closed under subtraction
The natural numbers are "closed" under addition and multiplication. ... The subtraction of two natural numbers does NOT necessarily create another natural number (3 - 10 = -7). The division of two natural numbers does NOT necessarily create another natural number (1 ÷ 2 = ½). not closed under subtraction and division.
The sum of two numbers is 75. One number is 5 more than 9 times the other number. What are the two numbers?
One number is 5 more than 9 times the other. If we represent the first number with x, we get the two numbers to be
x and
9+5x
The sum of the two numbers is 75. Plugging the two numbers into that equation, you get
x + 9+5x = 75
You can simplify to get
6x+9 = 75
By subtrating 9 from both sides, you get
6x = 66
Now you are practically done! You just need to divide both sides by 6 to get
x = 11
The two numbers were
x and
9+5x
By plugging x = 11 into both of the equations, you get
11 and
64 (64 is 55 + 9)
