Answer:

36 cards in each box

Step-by-step explanation:

Let the number of cards in each box be x.

4 * x / 3 = 48 (4 packs of cards, three friends)

x / 3 = 21

x = 36.

Answer:

36 cards in each box

Step-by-step explanation:

Because each friend gets the same amount of cards, there needs to be 48*3 or 144 trading cards in total. There are 4 boxes so in each box there would be 144/4 or 36 cards in total.

Answer:

I believe its 90

Step-by-step explanation:

You multiply each side by 5

5x5=25

double it for the other side

4x5= 20

double it

50+40=90

Answer:

no solution

Step-by-step explanation:

9x + 5 = 4(x+2) + 5x

9x + 5 = 4x + 8 + 5x

9x + 5 = 9x + 8

9x + 5 can never be equal to 9x + 8, so the answer is no solution

Answer:

x=3

Step-by-step explanation:

9x + 5 =4(x+2) + 5x

9x + 5= 4x + 8+ 5x ( do the parenthesis first- mulitiply  4 and x and get 4x and 4 times 2 = 8)

9x + 5 = 9x + 8 ( add the x's together 4x +5x = 9x )

9x = 9x + 3 ( subtract 5 both sides and you get 3 )

=3 ( subtract 9x from both sides

Answer:

21 ounces

Step-by-step explanation:

Answer:

15 ounces

Step-by-step explanation:

we know that the whole is 30  we know that Alex 1/10 and glen has 2/5 we dont know wht left over :: 1/10 + 2/5 = 1/10 + : 4/10 = 5/10 so 1 - 5/10 = 5/10

We need to find how many ounces of clay are left. Which equation can we use to find how many ounces are in 5/10

of the whole bucket?    5/10 x 30  and 5x 30 10

15 onces

Answer:

0.30 of a book / hour or 3/10 of a book per hour.

Step-by-step explanation:

Usually I tell people to put the numbers into decimals. Unfortunately for this question, it won't work. So we have any choice but to do it with fractions.

r = amount / time

amount = 1/4

time = 5/6

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

Invert the denominator and multiply

r = [tex]\frac{1}{4} * \frac{6}{5}[/tex]

r = 6 * 1 / (5*4) = 6/20 = 3/10

The answer is 3/10 of a book per hour

5/6 of an hour is almost an hour.

1/4 of a book is 0.25 of a book.

3/10 of a book is 0.30 of a book. So it looks like it is just about right.

Answer:

3/10

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that the fair spinner is numbered 1 - 5, the factors of 15 there are 1, 3 and 5 hence the probability of obtaining a factor of 15

= 3/5

The probability of obtaining a tail from the flip of a coin

= 1/2

Hence the probability of obtaining a factor of 15 and a tail

= 3/5 * 1/2

= 3/10

Answer:

130z-3

Step-by-step explanation:

Break down the equation:

(9[tex]z^{2}[/tex]-4)=

9z * 9z= 81z

You can't subtract 4, so I left it at (81z- 4)

(7[tex]z^{2}[/tex]+ 1)=

7z * 7z= 49z

You can't add 1, so I left it at (49z+ 1)

Then Solve:

You can add 81z and 49z.

81z+49z= 130z

-4+1= -3

Hope this helps!

Answer

B. number five is right

Step-by-step explanation:

Answer:

$5

Step-by-step explanation:

First, subtract the $6 toy from the total of $71.

$71 - $6 = $65

The total of the shirts and pants is $65.

She bought 9 shirts and 4 pants, which would be 13 shirts and pants.

We then divide the total cost of the shirts and pants, $65 by the total shirts and pants, 13.

65 / 13 = 5

So, each shirt or pants costs $5.

Answer:

12.5 km

Step-by-step explanation:

2cm = 5km

3cm = 7.5km

4cm = 10km

5cm = 12 5km

Answer:

F. 4 2/3 centimeters

Step-by-step explanation:

since the trapezoids are similar to each other, that means there is a common ratio between them. so taking into consideration the first trapezoid STUV when we compare that to NOPQ, OP comes out to be 4 and 2/3 centimeters. start by comparing the ratio of ST to NO and then move on to TU and then OP.

. Since the pentagon is a regular pentagon, the measure of each interior angle will be the same.

To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.

(which is the same as the number of sides).

540° ÷ 5 = 108° There are 108° in each interior angle of a regular pentagon.

2. 540°

Sum of Interior Angles of a Polygon

A pentagon has five sides, thus the interior angles add up to 540°, and so on.
