Given: Yu, Nailah, and Elena each bought between 7 and 9 yards of ribbon Yu bought 3 pieces of ribbon. Nailah bought 5 pieces of ribbon. Elena bought 6 pieces of ribbon.
To find: Who can buy which ribbon
Solution:
Ribbon Sizes
1 2/3 = 5/3 yard
4/5 yard
3 1/2 = 7/2 Yard
Yu, Nailah, and Elena each bought between 7 and 9 yards of ribbon
Yu bought 3 pieces of ribbon
=> 3 * 5/3 = 5
3 * 4/5 = 2.4
3 * 7/2 = 10.5
Nailah bought 5 pieces of ribbon
=> 5 * 5/3 = 8.33
5 * 4/5 = 4
5 * 7 /2 = 17.5
Elena bought 6 pieces of ribbon
=> 6 * 5/3 = 10
6 * 4/5 = 4.8
6 * 7 /2 = 21
Only value between 7 & 9 is 5 * 5/3 = 8.33
hence Nailah only can buy 1 2/3 = 5/3 yard ribbon
or there is some mistake in the data
54+x=12+3x
X=21 =number of classes
Total amount she will pay is $75
Answer:
Use inverse cos to solve for x.
hope this helps
Answer:
10. 108
11. 1,100
<em><u>12.</u></em>
-11 + 13 = 2
35 + -5 = 30
6 + (-3) +4 + 6 + (-5) = 8
5 + (-4) + (-9) + 8 = 0
(6) (8) = 48
(-2) (9) = -18
(-11) (-4) = 44
-256 divided by 0 = 0
-96 divided by +3 = -32
-36 divided by 3 = -12
