Answers

Answer: The number of girls= 20 and the number of boys=30

Step-by-step explanation:

Given : The ratio of girls to boys on a soccer team is 2 to 3.

=2:3

Let the number of girls be 2x

and total students will be 2x+3x=5x

Total number of players=25

$\Rightarrow5x=25\n\Rightarrow\ x=(25)/(5)\n\Rightarrow\ x=5$

then number of girls= 2x= 2 × 10=20

and the number of boys=3x=3 × 10=30

$2x-\ girls\n\n3x-\ boys\n\n2x+3x=25\n\n5x=25\ \ \ | divide\ by\ 5\n\nx=5\n\n2x=2*5=10\n\nThere\ are\ 10\ girls.$

A pair of jeans costs $89.A Jean jacket costs twice as much. What is the total cost of a jean jacket and 4 pairs of jeans?

Answers

It is given here that the cost of a pair of jeans is $89. It is also given in the problem that a jeans jacket costs twice as much as the pair of jeans.
Now
The cost of the jeans jacket = (2 * 89) dollars
   = 178 dollars
Cost of 1 pair of jeans = 89
So
The cost of 4 pairs of jeans = (89 * 4) dollars
   = 356 dollars
So we come to know that the cost of a jean jacket is $178 and the cost of 4 pairs of jeans is $356.
Total cost for the jean jacket and 4 pairs of jeans = (178 + 356) dollars
   = 534 dollars
So $534 is the total cost of the jean jacket and 4 pair of jeans.

20%

Answers

Any time you are solving a problem with percentages, use the formula below% = Is--- ----100 OfPercent over 100 = "is" over "of"In this case you are solving for percent and the "is" over "of" is $2 / $40Then you cross multiply and divide.100 x $2 = $200. 200 divided by 40 = 5. So the answer is 5

2/40 simplifies to 1/20. Multiply both top and bottom by 5 and you get 5/100. So 5%.
