Five times the greatest of three consecutive even integers is equal to twice the sum of the other two integers plus 42. What are
Levart [38]
We can represent the three integers with x, x + 2, and x + 4
This shows that the integers ascend in two units at a time, which are consecutive even integers. Next we can just translate the equation straight through.

5(x+4)=2(x + x + 2 + 42)
5x + 20 = 2(2x + 44)
5x + 20 = 4x + 88
x = 68

The integers are 68, 70, and 72

What is 1/4 of 1/2 ................................
jasenka [17]

Answer:

1/8

Step-by-step explanation:

When you are dividing by fractions you flip and multiply this also go's for when you multiply a fraction you flip and divide. what makes it easier is to put it in decimal form so 1/4 = .25 and 1/2 = .50 so what is 25/50? so it would come back to .125 which is equal to 1/8. If you are not very good at math just ignore this lol
