The ratio ...
... seniors : juniors = 3 : 2
can be multiplied by 7 to get
... = 21 : 14
indicating there are 14 juniors for the 21 seniors in the choir.
-88 = 2 + 2(5m - 5)
Distribute 2 inside the parentheses.
-88 = 2 + 10m - 10
Combine like terms on the right side.
-88 = -8 + 10m
Add 8 to both sides.
-80 = 10m
Divide both sides by 10.

Answer:
y+9=1/5(x+3)
Step-by-step explanation:
Point slope formula: y-y1=m(x-x1)
slope=m
m=1/5
-3=x1 -9=y1
y-(-9) =1/5(x-(-3))
simplify...
y+9=1/5(x+3)

Answer:
Step-by-step explanation:
EXAMPLE #1:
What number is 75% of 4? (or Find 75% of 4.)
The PERCENT always goes over 100.
(It's a part of the whole 100%.)
4 appears with the word of:
It's the WHOLE and goes on the bottom.
A proportion showing one fraction with PART as the numerator and 4 as the denominator equal to another fraction with 75 as the numerator and 100 as the denominator.
We're trying to find the missing PART (on the top).
In a proportion the cross-products are equal: So 4 times 75 is equal to 100 times the PART.
The missing PART equals 4 times 75 divided by 100.
(Multiply the two opposite corners with numbers; then divide by the other number.)
4 times 75 = 100 times the part
300 = 100 times the part
300/100 = 100/100 times the part
3 = the part
A proportion showing the denominator, 4, times the diagonally opposite 75; divided by 100.
