Lee and Maya are collecting leaves for an art project lee collects 25/100 of the total number leaves needed. Maya collects 4/10

MrRissso [65]

Answer: The answer is $\dfrac{13}{20}.$

Step-by-step explanation: Given that Lee and Maya are collecting leaves for an art project. Let'x' be the total number of leaves needed in the project.

Then, the number of leaves collected by Lee is given by

$L_\ell=\dfrac{25}{100}x,$

and the fraction of the leaves collected by Maya is given by

$M_\ell=\dfrac{4}{10}x.$

Therefore, the total number of leaves collected by Lee and Maya altogether is

$L=L_\ell+M_\ell=\dfrac{25}{100}x+\dfrac{4}{10}x=\dfrac{25+40}{100}x=\dfrac{65}{100}x=\dfrac{13}{20}x.$

Thus, the total fraction of the leaves collected by Lee and Maya is

$\dfrac{13}{20}.$

patriot [66]

All you have to do is multiply 2.3 by 13 together to get 29.9. Then you would subtract that by the total volume which would get 107.64. That's the width.

What does x equal if x-10 divided by x-4 equals 50 divided by -6

harkovskaia [24]

Answer:

x=65/14

Step-by-step explanation:

(x-10)/(x-4)=50/-6

-50/6=-25/3

(x-10)/(x-4)=-25/3

x-10=-25/3(x-4)

x-10=-25/3x+100/3

x-(-25/3x)=100/3+10

x+25/3x=130/3

28/3x=130/3

x=(130/3)/(28/3)

x=(130/3)(3/28)

x=130/28

x=65/14
