1. suppose a friend has just given you $25. this increased your total amount of cash to
$45. how much money did you start with?
step 1: define the variable. (hint: the variable shown is the first letter of the word it
defines.) (2 points)
m
=
step 2: write an equation to describe the situation using the variable defined in step 1.
(2 points)
step 3: solve the equation you wrote in step 2. (hint: use the reverse operation
performed to m.) show your work. (2 points)
step 4: explain the solution you found in step 3. (2 points)

they will manufacture 8496 cars

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

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
