Answer:
There are 60 6th graders in band.
Step-by-step explanation:
Let x represent the number of 6th graders in band. If there are 25% more in 7th grade, you can write it as (5/4)x. (You could also say 1.25x, but I think fractions would be easier in this situation.) Set up an equation:
x+(5/4)x=135
Now solve for x.
(4/4)x+(5/4)x=135
(9/4)x=135
(1/4)x=15
x=60
There are 60 6th graders in band.
Hope I could help you!
Answer:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
