Yu and Elena each bought between 7 and 9 yards of ribbon. Yu
Mumz [18]

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

(8x - 35) solve for x
skad [1K]
You must begin by isolating the x.
1. add -35 to the other side of the equation

2. divide by 8 to get x by itself

Hope this helps!

What is the slope for (6,2) (9,8)
fredd [130]

Answer:

3/6

Step-by-step explanation:

The slope is how one number gets to the next, in this instance we have point (6,2) at x=6 y=2 to get from there to the next point x=9 y=8 we would have to count up three and over six. Therefore, the answer is 3/6.

Hope this helps!

Please explain and/or show your work!! :)

\left[ \begin{matrix} 2 & a \\ -1 & -2 \end{matrix} \right] + \left[ \begin{matrix} b & 4 \\ -2 & 1 \end{matrix} \right]

This addition of matrices can be combined into one matrix.
To add matrices, add the corresponding components of each matrix.

After adding, we'll have the following

\left[ \begin{matrix} 2+b & a+4 \\ -3 & -1 \end{matrix} \right]

This matrix should be equal to the matrix on the right-hand side of the equation. This means that each corresponding component of this matrix and the other matrix should be equivalent.

This means that

2+b=1
AND
a+4=0

Solving these one-step equations will give the values of a = -4 and b = -1. That's answer choice D.
