5 divide 3 1/3

Answers

Answer:

3/2 or 1 1/2

Step-by-step explanation:

5÷3 1/3

5/1 ÷ 10/3 because you have to get it into an improper fraction form in order to divide

5/1 × 3/10 because you have to multiply the first number by the reciprocal

5  and 10 cancel out so you would have 2 at the bottom

Lupe is the manager of the football team, and she has to plan a team dinner for Saturday night. She knows that one large pizza can feed 3 players and one sandwich tray can feed 4 players. Lupe needs to order enough food for the 72 players on the team. (a) Write a linear equation to represent the number of pizzas (x) and the number of sandwich trays (y) she could purchase to feed the football players.

Answers

Answer:

3x + 4y = 72

Step-by-step exlanation:

Number of pizzas = x

Number of sandwich trays = y

one large pizza can feed 3 players

one sandwich tray can feed 4 players

Total players = 72

The linear equation is

3x + 4y = 72

The difference of two numbers is 18. Their sum is 66. What are the numbers? List the numbers from least to greatest.

Answers

5y
Another solution is to solve one equation for one variable, and plug that into the other equation.

x + y = 66
x = 66 - y

(66 - y) - y = 18
66 - 2y = 18
-2y = 18 - 66
-2y = -42
-2y/-2 = -42/-2
y = 24

Now that you have y, plug that into the first equation and solve for x.

x + 24 = 66
x = 66 - 24
x = 42

Then plug your two answers into both original equations to verify.

x + y = 66
42 + 24 = 66
66 = 66 check

x - y = 18
42 - 24 = 18
18 = 18 check

Deanna knows that the floor in her kitchen is a square with an area of 169 ft2. The perimeter of her kitchen floor is found by adding the lengths of all its sides. What is the perimeter of her kitchen floor? Explain how you found your answer.

Answers

Answer:

52 ft

Step-by-step explanation:

area of a square is l x w. all sides are equal so the l = w

A = 169 ft^2 so each side is the square root of 169 which is 13 ft

perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal

Perimeter = 13ft × 4 = 52 ft

so:

Answer:

52m

Step-by-step explanation:

Area of the square floor = 169 m²

For a square with each side 's' , area will be s². Similarly , for a square with area 'a' , length of each side will be √a.

So,

Length of each side of floor = √169 = 13m

For a square with each side 's' , its perimeter will be 4s.

Hence ,

Perimeter of the kitchen = 13 × 4 = 52m

Which number line represents the solution to 5x ≥ 30?

Answers

Answer:

Its B

Step-by-step explanation:

since the symbol has a line underneath its shaded so A & B are left.

the symbol shows > so the point is where the line goes, for this question it goes to the right.

The required number line represents the solution to 5x ≥ 30 is shown in option B.

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
According to the question, the inequality 5x ≥ 30 can be solved by dividing both sides by 5, which gives x ≥ 6. This means that any number greater than or equal to 6 is a solution to the inequality.

Looking at the number line options, we can see that only the last one correctly represents the solution to the inequality. The line starts at 6 and includes all numbers greater than or equal to 6, which matches the solution x ≥ 6.

Therefore, the correct answer is the number line shown in option B.

Answers

Answer:

Sorry, I tried.

Hope this helps.

Step-by-step explanation:

The chosen topic is not meant for use with this type of problem. Try the examples below.

6x2+3y2=126x2+3y2=12 , x+y=2x+y=2

x+2y=4x+2y=4 , x−y=−3x-y=-3

x2−y=2x2-y=2 , 2x−y=−12x-y=-1

Y:
-5y + 87 = -18
-5y = -18 - 87
-5y = -180
y = -180 / -5
y = +36

X:
( 5 x 36 ) + 2x = 58

180 + 2x = 58

2x = 58 - 180

2x = -122

x = -122 / 2

x = -61

A painting measures 2.4 feet from left to right. It’s hung in the center of a rectangular wall measuring 20 feet from left to right. What is the distance between the right edge of the painting and the right edge of the wall? Assume that the painting does not tilt.
A. 7.6 feet
B. 8.8 feet
C. 17.6 feet
D. 18.8 feet

Answers

So you want to figure out how much wall space isn’t covered by the painting, so 20-2.4. Then you need to divide your answer by 2 because it is in the center of the wall. So your answer is B. 8.8 feet hope that helps!

B) 8.8

(20-2.4)/2 = 8.8

Solve the following two equations. Show all of your
steps in the line paper provided. Be ready to share your
work!
Equation #1: 3x + 6 = x - 24
Equation #2: 10 – 2m = 16

Answers

Answer:

x = -15

m = -3

Step-by-step explanation:

3x + 6 = x - 24

subtract the x from both sides to make the unknown variable on only one side of the equation

2x + 6 = -24

subtract the 6 from both sides to focus on the x

2x = -30

now divide both sides by 2 to get the x by itself

x = -15

that's your answer

10 - 2m = 16

subtract the 10 from both sides to focus on the m

-2m = 6

now divide both sides by -2 to get the m by itself

m = -3

that's your answer
