5 1/2 - u = 9/4          U= 13/4

Basically you have to get the variable (u) by itself. Doing this by doing the opposite of what it’s doing to both sides of the equation.

dsp73
Divide amount of grapes by number of people.

= 1/2 lb ÷ 4 people

to divide a fraction, multiply by the reciprocal (inverse)

= 1/2 * 1/4
= (1*1)/(2*4)
= 1/8 pound

ANSWER: Each of the 4 people will get 1/8 pound of grapes.

Hope this helps! :)

3x - 5y = 19; x=-1 ,0, 1
EleoNora [17]

Answer:

Step-by-step explanation:

When x=-1

Substitute into the given equation

3(-1)-5y=19

-3-5y=19

Add 3 to both sides

-5y=22

Divide both sides by-5

y=-22/5

When x=0

3(0)-5y=19

0-5y=19

-5y=19

Divide both sides by-5

y=-19/5

When x=1

3(1)-5y=19

3-5y=19

Substrate 3 from both sides

-5y=16

Divide both sides by-5

y=-16/5

Therefore when x=-1,y=-22/5

When x=0,y=-19/5

When x=1,y=-16/5
