Answer:

There are more boys than girls. The red chips are girls are the boy are the yellow chips.  If more yellow chips were pulled out then there are more boys. 11 + 9 = 2. 10 + 9 = 19 + 1 = 20. The fraction of how many boys there are would be 11/21 and the fraction for girls would be 9/21.  Also 11 x 9 = 99. There would be 99 people if you times the number of girls and boys. But it's best to add because it would be in the smaller form if you were to times it.

Find the difference in length between a walking stick and a bumblebee PLS HELP HURRY​
Tanya [424]

Difference between the lengths of walking stick and lengths of bumble bee is 3\frac{4}{8} inch.

Solution:

Given data represents the length of the insects.

Length of the walking stick = 4 in

Length of the bumble bee = \frac{5}{8} in

Difference between their length

                                        $=4-\frac{5}{8}

                                        $=\frac{4}{1} -\frac{5}{8}

To make the denominator same, multiply and divide the first term by 8.

                                        $=\frac{32}{8} -\frac{5}{8}

                                        $=\frac{32-5}{8}

                                        $=\frac{27}{8}

Now, change improper fraction into mixed fraction, we get

                                         $=3\frac{4}{8}

Difference between the lengths of walking stick and lengths of bumble bee is 3\frac{4}{8} inch.

Find the sum.
Strike441 [17]

You are gonna use the distributive property.

4(2.5g - 4) + 3(1.2g - 2)

So you are going to multiply 4 with everything inside the first set of parenthesis and your gonna multiply 3 with everything insides the second set of parenthesis.

4 x 2.5g - 4 x 4 + 3 x 1.2g - 3 x 2

10g - 16 + 3.6g - 6

You wanna combine like terms:

10 - 3.6g + 16 - 6

6.4g + 10

You answer is 6.4g + 10.

Hope this Helps!!

Si se compran tres chicles y un tamarindo y se paga $15 y se compran dos chicles y tres tamarindos y se paga $31 ¿que cuesta cad
lorasvet [3.4K]

Responder:

9

Explicación paso a paso:

Dejar :

Mascar chicle = x

Tamarindo = y

3x + y = 15 - - - (1)

2x + 3y = 31 - - - (2)

De 1)

y = 15 - 3x - - (3)

Por lo tanto,

2x + 3 (15 - 3x) = 31

2x + 45 - 9x = 31

-7x = 31 - 45

-7x = - 14

x = 2

De (3):

y = 15 - 3 (2)

y = 15 - 6

y = 9
