3boys=6 supplies (1 notebook and one pencil per student)

if there are a total of 10 people:
10-3-1= 6 girls
girls=12 supplies
total supplies=18 supplies

Answer from: MannyBanko1350

Assuming there is no teacher:
1.) Since we know that each boy gets one notebook and one pencil, you can calculate total supplies using multiplication and them addition.

Notebook: 1×3 = 3
Pencil: 1×3 = 3
Total: 3+3 = 6

2.) Since we know there are 10 total people and three are guys, we can find how mnay girls there are using subtraction.

10 - 3 = 7 girls

3.) We can find their supplies using the same procedure as the boys just with 7 girls instead.

Notebook: 1×7 = 7
Pencil: 1×7 = 7
Total: 7+7 = 14

4.) To find the entire total, we just add the boys and the girls totals.

6 + 14 = 20

If there is a teacher, then there are 9 students in which 6 are girls.

6× 1 = 6
6 × 1 = 6
6 + 6 = 12 total for girls
and 12 + 6 = 18 total for the class.

I hope this helps!

Answer from: Quest

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
