First row all correct second rows all wrong and the first on of third row is correct be the last two are incorrect
Answer:
add then subtract the anwser
A(w)=50w-w2 if the perimeter is 100, I plugged in possible values for the width...I used w=15 and length = 35 for a perimeter of 100. then I plugged these values in the possible equations until I found the correct one giving me an area of 525 (15x35) . I could not think of an easier way.
Width = w
d)length in term of width
w + 5
b)
2(w + w + 5) > 30
2(2w +5)>30
c)
solve
2(2w +5) > 30
4w + 10 > 30
4w > 20
w > 5
Hi Eli!
--------------------------------------
We Know:
1 1/2 cups of flour.
3/4 cup of white sugar.
1/8 cup of brown sugar.
--------------------------------------
Part A:
I can't use a number line answering this question but you can create one with the steps I tell you.
First find common denominators:
1 1/2 = 3/2 = 12/8
3/4 = 6/8
1/8
Create a number that goes from 0/8 to 12/8, which means put a number with 12, 1/8 plots on it. Then plot 12/8, 6/8, and 1/8 in order in the number line.
Find out the total number of cups used:
12/8 + 6/8 + 1/8 = 19/8
Simplify:
19/8 = 2 3/84
Part A Answer: There are <u>2 3/8 cups</u> used all together.
--------------------------------------
Part B:
Part B Answer: The <u>3 cup bowl</u> would work perfectly.
Why: The reason you would want to choose the 3 cup bowl is because it fits all the ingredients perfectly, the 3 cup bowl is greater than the 2 3/8 cups they used. You can't use 2 cups because it is less than the total cups of ingredients. The 4 bowl you could use but it is too big.
--------------------------------------
Hope This Helps :)
