5 0

Answer:

Lisa is 5 years old

Step-by-step explanation:

we can make an equation like

4x=15+x

X can represent Lisa’s current age

Now just solve for X

3x=15

x=5

And we can check

If Lisa is 5 years old now

In 15 years she would be 20

And 20 is 4 times as 5 which Is her current age

So Lisa is 5 years old now.

A glass is 1 3 full. Then 40cm3 of orange juice is poured in. The glass is now 5 7 full. What is the total volume of the glass?
Effectus [21]

Answer:

V= 105cm^3

Step-by-step explanation:

V=volume

(1/3)V+40=(5/7)V

(5/7)V-(1/3)V=40

(15/21)V-(7/21)V=40

(8/21)V=40

(21/8)(8/21)V=(21/8)(40

V=21*5

V=105 cm3

(1/3)(105)=35, 35+40=75, 75/105=15/21=5/7
