Justin can replace three windows in an 8 hour day. How many hours will he need to replace 20 windows on a house

Answer: fries=$3.20, burgers=$5.79

Step-by-step explanation:

(f=fries, b=burger)

21.18=2b+3f

29.56=4b+2f

-2(21.18=2b+3f)

 29.56=4b+2f  

-42.36=-4b-6f

29.56=4b+2f

  -12.8=-4f

    3.2=f

21.18=2b+3(3.2)

21.18=2b+9.6

-9.6         -9.6

11.58=2b

 5.79=b

Answer:

1.) -2

2.) -2

3.) -3

Step-by-step explanation:

Since we can't make a graph, we can make a table

(-5,13) and (1,1)

x       y

-5      13

1        1

From 13 to 1, you subtract 12 ( y-section)

From -5 to 1, you add 6 (x-section)

Now we can do y/x

y/x = 12/6 = -2

The slope for this first one is (-2).

(-5,14) and (12,-21)

x           y

-5          14

12         -21

From 14 to -21, you subtract 34

From -5 to 12, you add 17

Now we can do y/x

y/x = -34/17 = -2

The slope for this second one is (-2)

(1,1 )and (12,-21)​

x        y

1        12

12     -21

From 12 to 21, you subtract 33

From 1 to 12, you add 11

Now we can do y/x

y/x = -33/11 = -3

The slope for this third one is (-3)

Step-by-step explanation:

After solving the equation, the smaller piece length of the rope will be 30 meters.

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the data provided in the given question,

3x+20+x = 140

4x+20 = 140

4x = 120

x = 30 meters

The smaller piece of the rope is of 30 meters.

Answer:

100 minutes or 1.666666 hours or 1 and 2 thirds

Step-by-step explanation:

first do 60x5 because 1 hour is 60 minutes so we get 300 then divide by 3 because of the three sports.

The third part of 5 hours is 1 hour and 40 minutes thus Jason spent 1 hour and 40 minutes in each activity.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Division = divide any two numbers or variables called division.

For example 4/8

As per the given,

Jason spent 5 hours during the weekend practicing his 3 sports and music activities.

Since, time is equal thus per activity, 5/3 hours are spent.

(5/3) x 60 = 100 minutes.

(60 minutes + 40 minutes) = 1 hour and 40 minutes.

Hence "The third part of 5 hours is 1 hour and 40 minutes thus Jason spent 1 hour and 40 minutes in each activity".

Answer:

x=21/5, also known as 4.2

Step-by-step explanation:

5x:9 = 7:3

Solve it like a proportion and get any of these answers

5x/9 = 7/3

cross product property

3(5x) = 63

15x = 63

x = 63/15 = 21/5 in fraction form = 4.2 in decimal form
