13. A car travels 30 ⅕ miles in ⅔ of an hour. What is the average speed, in miles per hour, of the car?

Answer:

5/6

Step-by-step explanation:

1 4/6-5/6=?

1 4/6=10/6

10/6-5/6=5/6

Answer:

five sixths pound

Step-by-step explanation:

Kip bought [tex]1\frac{4}{6}[/tex] pounds of toffee. He gave [tex]\frac{5}{6}[/tex] of a pound to his friend. How much toffee does he have left?

The narrator is asking how much he has left after giving some toffee to his friend, that means we have to subtract.

[tex]1\frac{4}{6}[/tex] - [tex]\frac{5}{6}[/tex]

We already have an equal denominator so we can just subtract.

[tex]\frac{10}{6}-\frac{5}{6}[/tex] = [tex]\frac{5}{6}[/tex]

Kip has [tex]\frac{5}{6}[/tex] pounds left.

Answer:

There would be 17 cookies in three rows. There would be 12.75 for 4 rows.

Step-by-step explanation:

All you have to do is 51 divided by how many rows you have.

Answer

1. 17        2. 68

Step-by-step explanation:

ok so divide 51 by 3 to get 17 for the first part and the second part multiply 4 and 17 to get 68.

Answer:

16 red and 20 blue

Step-by-step explanation:

If you look at the picture there is 16 red

So add 16+64=80 then 80+20=100

16 red

20 blue

64 yellow

Answer:

B (4)

Step-by-step explanation:

[tex]\frac{9+7}{3+1}[/tex] = [tex]\frac{16}{4}[/tex] = [tex]\frac{4}{1}[/tex] = 4

Answer:

t's 11 weeks because if you multiply 20*11 you get 220 then add 80 and you have $300

Answer:

29.25

Step-by-step explanation:

This is a simple function table we are working with, so we see that 2 (pounds) would cost around $4.50. So Next we look at 4 would equal $9. By doing this I divide 9 by 4 to get the answer of 2.25. This is are new function table rule of C=P x 2.25. Now that we have this we know that 13 is are P (pounds) and we are looking for are C (cost) After we input 13 into are function rule. We get the answer of $29.25.

Answer:  well 14 pounds cost $31.50

so that means 13 pounds cost $29.50

Answer:

24

Step-by-step explanation:

[tex]4\frac{3}{5} -(-3\frac{2}{5})+3[/tex]

Negative and another negative makes a positive.

[tex]4\frac{3}{5}+3\frac{2}{5}+3[/tex]

Add the fractions first.

[tex]7\frac{5}{5}+3[/tex]

5/5 is equivalent to 1. 7 5/5 becomes 8.

[tex]8+3[/tex]

Add the numbers.

Answer:

the first one should be 5.28x10^-2 and the second one should be 3.2x10^6

Step-by-step explanation:

because with 0.0528 you move the decimal right twice. which makes it negative.

with 3,200,000 you assume that the decimal is at the end and move it between the three and the two. making it have 6 moves. since it moves left its positive

Answer:

0.0528=5.28*10^-2

Step-by-step explanation:

Scientific notation is a simpler way to write very large or very small numbers. In this case, you want to write a small number in simpler form. To write in scientific notation, the number being multiplied always has to be between 1 and 10. Here, it is 5.28, so we aren't breaking the rule. You can see that we moved the decimal two places to the right, which is going to make the exponent negative (the opposite applies for larger numbers). To convert to scientific notation, move the decimal place to the right or left until you get a number between 1 and 10. Then, if you moved to the right, multiply the number that is between 1 and 10 by 10 the the negative [# of spaces that you moved the decimal] power. If you moved it left, do the same but a positive exponent. To convert from scientific notation, write the number that is being multipied by 10 on a sheet of paper. if the exponent is negative, you'll have to move the decimal left for every number that the exponent is. For example, if the exponent was -5, you would move the decimal to the left 5 times. If it was just 5, you would move the decimal to the right 5 times. Then, there's your number.

Answer:

x = 4.125 or [tex]4\frac{1}{8}[/tex]

y = -0.875 or [tex]-\frac{7}{8}[/tex]

Step-by-step explanation:

5x + 3y = 18

3x - 3y = 15

3y and -3y can be cancled out becuase + and - cancel out and they both have 3y in them. We don't have to switch any signs in this case. You can just add them all exept 3y and -3y becuase they will be canceled out.

8x = 33

x = 4.125

Now we know what x is. We need to figure out what y is now. To figure out y chose an equation from the problem and plug in the x value. Lets chose 3x - 3y = 15.

3(4.125) - 3y = 15

12.375 - 3y = 15

-3y = 2.625

y = -0.875

Now we know what y is.  I hope this helps :)

Solve for the single variable in the one-variable equation.

Step-by-step explanation:

Answer:

We know that the kite with the tail is 15 feet and 6 inches. While 6 inches is 0,50 foot, it's 15,5 feet. If the lenght of the kite is x, then:

15,5 = x + 1,5 + 2x

15,5 = 3x + 1,5     / - 1,5 (both sides)

14 = 3x             / : 3 (both sides)

x ≈ 4,66

The kite is approx .4,66 feet long. It means that the tail is about 15,5 - 4,66 = 10,84 feet long.

Answer:

10 5/6 feet

Step-by-step explanation:

Tail= 1.5+2Kite

Kite+Tail=15.5

x+1.5+2x=15.5

3x=15.5-1.5

3x=14

x=14/3=4 2/3

Kite=4 2/3

Tail= 1.5+2(4 2/3)=10 5/6
