Laura is three times as old as luci. in 5 years, the sum of their ages will be 30. what are the current ages of laura and luci?

Laura = 15 , Luci = 5

Step-by-step explanation:

                Now:                            In 5 yrs:                      

Laura =      3x                                     3x+5

Luci   =        x                                       x+5

Equation: 3x+5+x+5 = 30

                    4x+10 = 30

                         -10    -10

                         4x = 20

                           x = 5

 In conclusion, Laura = 3x = 15 & Luci = x = 5

the answer is 15% decrease

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
