Answer:
Maria made 248 cookies, Denise made 62 cookies, Joseph made 372 cookies.
Step-by-step explanation:
Number of cookies made by Maria is m,
made by Denise is d,
made by Joseph is j
We can write the following equations from the word:
m = 4d
j = 6d
m + d + j = 682
We can substitute both 1st and 2nd equation in 3rd and solve for d:
m + d + j = 682
4d + d + 6d = 682
11d = 682
d = 62
Thus,
m = 4(62) = 248
and
j = 6(62) = 372
Maria made 248 cookies, Denise made 62 cookies, Joseph made 372 cookies.
Step-by-step explanation:
12a-9a>-12+6
3a>-6/:3
a>-2
L=2w-5
2(l+w)=80
l+w=40
2w-5+w=40
3w=45
w=15 feet
l=25 feet. As a result, the width is 15 feet and length is 25 feet. Hope it help!
Answer:
its 3rd choice lol
Step-by-step explanation:
If you would like to know two equivalent ratios for 12/60, you can calculate this using the following steps:
12/60 = 12/2 / 60/2 = 6/30
6/30 = 6/2 / 30/2 = 3/15
3/15 = 3/3 / 15/3 = 1/5
The result would be 6/30 or 3/15 or 1/5.
