If 9(1-x) = 27Y and x-y=-11/2, find the value of x + y.

Finger [1]

Answer:

-2.25

Step-by-step explanation:

9(1-x) = 27Y

9-9x =27y

-9x -27y = -9 multiply all terms by -1

9x +27y =9 equation (1)

x-y= -11/2 equation (2)

by solving 2 equations

x= -3.875

y= 1.625

∴ x+ y = 1.625 +(-3.875) = -2.25

Rachel saved money to buy art supplies. She used 13 of her savings to buy brushes. She used 35 of her savings to buy paint. What

vekshin1

Given:

Rachel used $\dfrac{1}{3}$ of her savings to buy brushes.

She used $\dfrac{3}{5}$ of her savings to buy paint.

To find:

The fraction for remaining savings.

Solution:

Fraction that Rachel used of her savings to buy brushes and paint is

$\text{Fraction for used amount}=\dfrac{1}{3}+\dfrac{3}{5}$

$=\dfrac{5+9}{15}$

$=\dfrac{14}{15}$

Now,

$\text{Fraction for remaining savings}=1-\text{Fraction for used amount}$

$\text{Fraction for remaining savings}=1-\dfrac{14}{15}$

$\text{Fraction for remaining savings}=\dfrac{1}{15}$

Therefore, $\dfrac{1}{15}$ of her savings is remaining.
