3. Ron used 24 cubes to make this 3-step staircase. If he uses a total of 84 cubes to make a similar staircase, how many steps will the staircase have?
Answers
Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)
28 steps because 84 divided by 3 equals 28

Do you remember how to find the equation of a line when you know two points on the line ? Well, that little table gives you FIVE points on the line, and in case some students didn't notice that, the table even labels the columns 'x' and 'y' as a hint. With 5 points given, there are 20 different ways to find the equation of the line. Get to work.
Okay first we need to find the line of best fit. We would need the slope and the y-intercept. First let's solve for slope.
We would need two coordinates from the table to fill in the data. Let's use (0, 23) and (1, 20).
Then we can solve for the y-intercept using the slope-intercept form: y = mx + b.

Rob is saving to buy a new MP3 player. For every $15 he earns babysitting, he saves $6. On Saturday, Rob earned $75 babysitting. How much money did he save?
Answers
First you have to see how many time 15 goes into 75, which is 5 so for every time 15 goes into 75 it would be another $6, so the answer is 6 * 5 which is $30. Hope this helps!
Answer:40

Denise has 1/2cup of vegetable oil that she will use in making several batches of cookies. Each batch requires 1/8 cup of vegetable oil. evaluate the expression below to find the number of batches of cookies Denise will make
Answers
First, you need to set the denominators equal. 1/2=4/8 Then divide. (4/8)/(1/8)=(4)/(1)=4. Notice that the denominators cancel each other out. You then have whole numbers that divide easily. The answer is that Denise can make 4 batches of cookies on 1/2 cup of vegetable oil.
