The ratio of the number of boys to the number of girls at school is 4:5. If there are 120 boys, how many total students are there? (Write the number only) *

150

Step-by-step explanation:

So first you divide 120 by 4 so you know how much times 4 was increased, 4 was increased by 30 times

Next you multiply 5 by 30 because 4 was multiplied by that much

The answer is 150 girls

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
