Girls group is 30+5=35

Boys group is 30-5=25

Answer:

<em>They will need 25 boy costumes and 35 girls costumes.</em>

Step-by-step explanation:

There are x boys.

There are x + 10 girls.

Altogether, there are x + x + 10 students.

Altogether, there are 60 students, so

x + x + 10 = 60

2x + 10 = 60

2x + 50

x = 25  (boys)

x + 10 = 35  (girls)

Fantom [35]

Answer:

Next  you need to mutiply 225 and .20 and you will get 45 (that means it is $45 off)

Subtract 45 fro 225 and that is your answer.

You now pay $180 for the 20 foot extension ladder.

How do you factor this?​
lubasha [3.4K]

Answer:

Step-by-step explanation:

What two numbers multiply to equal -48, but add to equal -2? The method is multiplying a*c and seeing if they add up to b. Those two numbers are -8 and +6.

6x^2-2x-8=6x^2-8x+6x-8

Now, factor by grouping

(6x^2-8x)+(6x-8)=2x(3x-4)+2(3x-4)\\(2x+2)(3x-4)
