Answer:
17 students
Step-by-step explanation:
Given:
There are some students playing soccer.
Five students decided to join the game and now there are twenty-two students playing soccer.
Question asked:
How many students were originally playing soccer?
Solution:
Let initially number of students playing soccer = 
As given,
<u>After joining 5 more students, there are 22 students playing soccer, the equation will be:-</u>
Subtracting both side by 5
Hence, 17 students were originally playing soccer.
Answer:
y= ab if a≠b
Step-by-step explanation:
y/a −b= y/b −a
multiply each side by ab to clear the fractions
ab(y/a −b) = ab( y/b −a)
distribute
ab * y/a - ab*b = ab * y/b - ab *a
b*y - ab^2 = ay -a^2 b
subtract ay on each side
by -ay -ab^2 = ay-ay -a^2b
by -ay -ab^2 =-a^2b
add ab^2 to each side
by-ay -ab^2 +ab^2 = ab^2 - a^2b
by-ay = ab^2 - a^2b
factor out the y on the left, factor out an ab on the right
y (b-a) = ab(b-a)
divide by (b-a)
y (b-a) /(b-a)= ab(b-a)/(b-a) b-a ≠0 or b≠a
y = ab
If it was a 75% discount, then u r actually paying 25%
so....25% of the original price is $ 11
0.25x = 11
x = 11 / 0.25
x = 44 <=== the original price
-1
The inequality is negative 1
