Answer:

Cost of a roll of plain wrapping paper = $6

Cost of a roll of shiny wrapping paper = $20

Step-by-step explanation:

Let [tex]x[/tex] denotes cost of a roll of plain wrapping paper and [tex]y[/tex] denotes cost of roll of shiny wrapping paper.

Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190.

[tex]5x+8y=190\,\,\,(i)[/tex]

Beth sold of 5 rolls plain and 3 shiny for a total of $90.

[tex]5x+3y=90\,\,\,(ii)[/tex]

Subtract (ii) from (i).

[tex]8y-3y=190-90\\5y=100\\y=20[/tex]

Put [tex]y=20[/tex] in (ii)

[tex]5x+3(20)=90\\5x+60=90\\5x=90-60\\5x=30\\x=6[/tex]

Therefore,

Cost of a roll of plain wrapping paper = $6

Cost of a roll of shiny wrapping paper = $20

Step-by-step explanation:

The angles add up to 180

Answer:

F and G

Step-by-step explanation:

120 and 60 degrees add up to 180, and supplementary angles need to add up to 180. Therefore, F and G are supplementary angles. Hope it helps!

The length of the rectangle is 14

steps:

9 + 9 = 18

46 - 18 = 28

28 ÷ 2 = 14

Answer:

Step-by-step explanation:

Step-by-step explanation:

you need to solve this using fractions.

Example :

It takes 3 men 8 hours to build a wall. How long would it take 4 men to build the same wall?

For 3 men: It is 1 wall divided by 8 hours, which is 1/8.

For 1 man: It is 1/8 divided by 3, which is 1/24.

For 4 men: It is 1/24 multiplied by 4, which is 1/6, = 6 hours.

[tex]t^{6}[/tex]

Step-by-step explanation:

I am going to assume exponents for this question.

[tex]\frac{t^{8}}{t^{2}}[/tex]

When dividing exponents with the same base, it is simply subtraction, so 8 - 2 = 6 which produces the answer.

Answer:

875 ft^3

Step-by-step explanation:

Pick them apart starting at the bottom. The formul used is V=lwh

Starting at the bottom we have we have a sqare of 5 ft = 5ft^3= V = 125 ft^3

Then we have a rectangular prism: 5 x 5 x 20 = V = 500 ft^3

Third we have 5 x 5 x 10 = V = 250 ft3

125+500+250 = 875 ft^3

Answer:

220.8 ounces

Chulo weighs 220.8 ounces

Answer:

1st option

Step-by-step explanation:

We see that one angle is 28, so because of alternate interior angles, angle two is also 28. Angle one is 90 because those two lines are perpendicular and the only available options for A is 90, and measurement angle 3 is going to be 180 - (90 + 28) (sum of interior angles in a triangle) and you're going to get 62.

Answer: 8

Step-by-step explanation:

Answer:

I dont know what your supposed to do but i can tell you that x = 5 because if you simplify the equation you get 3x + 5 = 4x. Using this you can infer that a single x is equivalent to 5 since you need 5 to get from 3x to 4x.

It will take 2.6 hours (or 2 hours and 36 minutes) long for the two trains to meet when Two trains leave stations 520 miles apart at the same time and travel toward each other.

To find the time it will take for the two trains to meet, we can use the concept of relative speed.

The two trains are traveling towards each other, so their speeds add up. The combined speed of the two trains is:

110 mph + 90 mph = 200 mph

To determine the time it will take for the trains to meet, we can divide the total distance they need to cover (520 miles) by their combined speed (200 mph):

Time = Distance / Speed

Time = 520 miles / 200 mph

Time = 2.6 hours

Therefore, it will take 2.6 hours (or 2 hours and 36 minutes) for the two trains to meet.

Answer: y=12/20=0.6

Step-by-step explanation:

Rephrase the given equation

1 and 1/5y+3/10y-1/2y=1/3y+2/5

6/5y+3/10y-1/2y=1/3y+2/5

Find the GCF (greatest common factor) and multiply it on both sides

(6/5y+3/10y-1/2y)×30=(1/3y+2/5)×30

36y+9y-15y=10y+12

Add like terms together

30y=10y+12

Subtract 10y on both sides

30y-10y=10y+12-10y

20y=12

Divide 20 on both sides

20y/20=12/20

y=12/20=0.6
