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
1. -7-(-2)
= -7+2= -5
2. 5-(-3)
= 5+3=8
3. -6-4
= -6+(-4)= -10
4. -3-(-3)
= -3+3= 0
Answer:
x = -6 x=5
Step-by-step explanation:
x^2 +x -30 =0
Factor
What two numbers multiply to -30 and add to 1
6 * -5 = -30
6-5 =1
(x+6) (x-5) =0
Using the zero product property
x+6 =0 x-5=0
x+6-6=0-6 x-5+5=0+5
x = -6 x=5
a). No. Variation in 'y' has no effect on 'x'.
b). No. Variation in 'x' has exactly the opposite effect on 'y'.
c). Yes. Variation in 'x' causes 'y' to vary 6 times as much in the same direction.
d). No. Doubling 'x' does not double 'y'.
Answer:
<em>IJ = 82</em>
Step-by-step explanation:
IJ≅IH so they are the same length
IH = 82 = IJ
