Yuri [45]

3/5= 3 fifth size strips
You want to find an equivalent fraction with the denominator of ten, correct? Then you would multiply the fraction in a way that will allow you to have a denominator of ten.
So...
3/5*2/2=6/10
You would need 6 tenth size strips.

Answer:

$y > \boxed{\cfrac{42}{5} }$

Step-by-step explanation:

Given inequality:

$\cfrac{y}{3} > 7 - \cfrac{y}{2}$

To solve for <em>y.</em>

Solution:

Rewrite the inequality as,

$\displaystyle \frac{1y}{3} > \frac{ - 1}{2} y + 7$

Adding 1/2y to both sides,

$\cfrac{1}{3} y + \cfrac{ 1 }{2} y > \cfrac{ - 1}{2}y + 7 + \cfrac{1}{2} y$

$\cfrac{5}{6} y > 7$

Multiplying both sides by 6/5:

$\cfrac{6}{5} \times \cfrac{5}{6} y > \cfrac{6}{5} \times 7$

$y > \boxed{\cfrac{42}{5} }$

Value of y is 42/5.

Zinaida [17]

This is NOT the graph of a function y=f(x). However, if you solve the original equation for y in terms of x, you can break the graph into two pieces, each of which is the graph of a function.

The real solution are : x= -4/sqroot7, y= 2/sqroot 7

x= 4/sqroot7, y= -2/sqroot 7

integer solution are: (-1,2) , (1,-2), (1,1)
