Martin put 8 pounds of grapes into a bowl. Four friends each took 2/3 pounds from the bowl. What fraction represents the total a
charle [14.2K]
There are 8 pounds of grapes. Four people each take 2/3 out. We can find out how much was taken out by multiplying these four people by the amount they took out, 2/3:

\sf 4\times\dfrac{2}{3}=\dfrac{8}{3}

We can convert this improper fraction to a mixed number. Three goes into eight two times. 3 * 2 = 6. 8 - 6 = 2. So we have 2 and two thirds leftover, or:

\sf 2\dfrac{2}{3}

So the total amount of grapes that was removed from the bowl is \sf\dfrac{8}{3} or \sf 2\dfrac{2}{3} pounds.

Given that B is between A and C. If AB=x, BC =2x-3, and AC = 30. Find x and bc
Artemon [7]

Answer:

x=11

BC=19

Step-by-step explanation:

AB+AC=AC this is because B is in between A and C. So now we can substitute all of the line segments, so we have

x+2x-3=30          Now you add 2x and x

3x-3=30      Now you add 3 to both sides so you can get 3x alone on one side

3x=33        Now you divide both sides by 3 so you get the x alone on one side

x=11

The next step is to substitute x to find BC.

BC=2x-3       Substitute the x with 11

BC=2(11)-3    Then multiply 2 and 11 because that is the rule with parenthesis

BC=22-3        then subrtact the 3 from 22

BC=19

You can check your work by doing AB+BC=AC

11+19=30        substitute your answers and then add them together

30=30
