John + Sissy + Phoebe = 159
63 + 83 + Phoebe = 159
146 + Phoebe = 159
Phoebe = 159 - 146
Phoebe = 13
Phoebe can buy 13 nuts.
Answer:
9
Step-by-step explanation:
180 x 0.05
Answer:
x < 9/55
Step-by-step explanation:
55x+2 is less than 11
we subtract 2 from both sides, then we divide both sides by 55.
x is less than 9/55
For this case we have the following variables:
P = area covered by a roll of wallpaper
w = the total area of the walls
n = number of rolls to buy
We write the equation for n.
You must take into account that you can determine this amount by dividing the total area between the area covered by each roll of paper.
We have then:
Answer:
a formula that will help them determine how much wall paper they'll need to purchase is:

Answer:
y=-4/10x+ 5 or y=-0.4x+5
Step-by-step explanation:
The formula for slope is y=mx+b. The "m" is the slope, the "x" is constant, and "b" is your y-intercept.
1. Figure out your slope:
Easiest way to do this is by using rise/run. You. take your point to the left and count how many spaces up or down it is from the second point, and then repeat that across the x-axis.
2. Determine whether it is positive or negative
A line with a positive slope is going to be angled upward and a line with a negative slope will be angled downward
3. Find the y-intercept
Simply look at the graph and find where the line crosses the y-axis
4. Plug everything into the equation
Once you do Steps 1-3, just plug everything in and you're done! If you have any questions, feel free to ask!
