Answer:
459 students.
Explanation:
Since you are given the number of how many students are in each section, simply multiply to find the total answer.
27 x 17 = 459
There are 459 students.
Answer:
x < -8
Step-by-step explanation:
To solve this inequality you would need to isolate the variable x.
Add 1 to both sides of the inequality.
Divide both sides of the inequality by 3.
When using substitution, you want to solve an equation for one variable that doesn’t make the equation worse to work with.
The general idea is that you want to find a variable that has a coefficient of 1 or -1.
In 2.5x - 7y = 7.5, both variables have “bad” coefficients.
In 6.2x - y = 1, the y has a coefficient of -1. That’s where you want to start.
So a square is a parallelogram with four sides of equal length and angles of equal size. <span>In other words, all squares are parallelograms, but only some parallelograms are squares.</span>
The first car is traveling at 65 miles per hour and the second car is traveling at 62 miles per hour.
Explanation:
390:x=372:(x-3)
372x=390(x-3)
372x=390x-1170
1170=390x-372x
1170/18=18x/18
x=65
x-3= 65-3=62
