Someone please help me on this math problem!

Galina-37 [17]

Look at the picture.

Therefore we have the equation:

10y - 29 = 7y + 19 add 29 to both sides

10y = 7y + 48 subtract 7y from both sides

3y = 48 divide both sides by 3

y = 16

3x + 7 = 5x - 21 subtract 7 from both sides

3x = 5x = -28 subtract 5x from both sides

-2x = -28 divide both sides by (-2)

x = 14

Collins Middle School has 240 sixth grade students. If the sixth grade is 30% of the total school, how many students are in the

Masteriza [31]

Answer:

800

Step-by-step explanation:

We can set up a proportion using the information we are given. We know that 240 students corresponds to 30% and that the total number of students, x, corresponds to 100%

$\frac{240}{x} = \frac{30}{100}$

Cross multiply and solve:

240 * 100 = 30x

24000 = 30x

800 = x
