Select all the equations that have the same solution as the equation 5x + 10 = 30? X+2 = 6
20x + 10 = 120
5x = 20
6x + 10 = 30 + x
5x = 40
15x + 30 = 90

Step-by-step explanation:

5x + 10 = 30

collect like terms

5x = 30 - 10

5x = 20

Divide both sides by the coefficient of x that's 5

so x = 4

Equations

x + 2 = 6

5x = 20

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
