Half of Robert's piece of wire is equal to 2 thirds of Maria's wire. The total length of their wires is 10 feet. How much longer
Yuliya22 [10]

Answer:

let x be the Robert piece

y Maria's piece

x+y=10

0,5*x ( half of Robert piece)= 2/3 y( 2 thirds)

2 equations then

x+y= 10 then x= 10-y

0,5x= 0,67 y  then we replace x by 10-y on the second equation and it gives

0,5(10-y)= 5-0,5y=0,67y

5= 1,17 y so y= 4,27    and then x= 10-y= 5,73

the question asks how much Robert wire is longer than Maria's wire

so we get x-y= 1,46

Mike makes 4 dozen cookies. He brings 75% of them for a party at his school. How many did he bring?
baherus [9]

Answer:

He brought 3 dozen cookies

She ate \frac{2}{5} of the bag of Doritos

She read 25 books

Step-by-step explanation:

∵ Mike makes 4 dozen cookies

∵ He brings 75% of them for a party at his school

- Multiply 75% by 4

∵ 75% = \frac{75}{100}=\frac{3}{4}

∴ He brought = \frac{3}{4} × 4

∴ He brought = 3

He brought 3 dozen cookies

∵ Sam bought a bag of Doritos

∵ She ate only 40% of them

∵ 40% = \frac{40}{100}=\frac{2}{5}

∴ She ate = \frac{2}{5} × 1

∴ She ate = \frac{2}{5}

She ate  \frac{2}{5} of the bag of Doritos

∵ Jamie took 50 books from the library

∵ She only read half of her whole stack

- Multiply half by 50

∴ She read = \frac{1}{2} × 50

∴ She read = 25

She read 25 books
