Answer:
112 students
Step-by-step explanation:
Let T be the total number of students in the band.
From the question,
We were told that 37.5% of the total owns their individual instruments and this amount to 42 students
The total number of students can calculated for as follows:
37.5% x T = 42
37.5/100 x T = 42
Cross multiply to express in linear form
37.5 x T = 100 x 42
Divide both side by 37.5
T = (100 x 42) /37.5
T = 112
Therefore, there are 112 students in the band

Answer: x = -9/ addition property of equality
Explanation: In this problem, we're given that x - 7 = -16 and we're asked to solve the equation and explain which equality we used.
The first statement we have will be
the given statement which is x - 7 = -16.
Now, we just solve the equation.
Our first and only step will be to add 7 to both sides.
Then, we find that x = -9.
The property we used here was the addition property of equality.
This property tells us that we can add the same quantity,
or equal quantities, to both sides of an equation.
