Paola is planning her summer vacation. she wants to buy maps and atlases to use in her planning. the maps cost $3.00 and the atlases cost $7.00 each. if she spends $43.00 what combination of maps and atlases can she buy ?

she can buy 5 maps and 4 atlases

Step-by-step explanation

add 3.00 and 7.00 again and gain untill you reach £43.

This what i typed in my calculator

3.00+7.00+3.00+7.00+3.00+7.00+3.00+7.00+3.00= £43.00

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
