Get all the x's on one side and everything else on the other side
x + 6x = -16 - 5
7x = -21
then divide by 7
x = -3

X +5 = -6x - 16
add 16 to both sides
x+21 = -6x
add 6x to both sides
7x+21=0
factor out the seven
7(x+3)=0

if 7 times (x+3) = 0 then (x+3) must equal zero because 7 times 0 is 0

so x+3=0
subtract three from both sides
x= -3

One shelf will hold 45 pounds of boxes. If you have to store 270 pounds of boxes, how many shelves will you need?

arlik [135]

Hi!

We will solve this using ratios, like this:

1 shelf holds 45 pounds

x shelves hold 270 pounds

______________________

x = (270*1)/45

x = 270/45

x = 6

6 shelves will be needed to hold 270 pounds of boxes.

Hope this helps!

Answer:

$\%Percent = 14.3\%$

Step-by-step explanation:

Required

15 is what percentage of 105

To do this, simply divide 15 by 105 multiplied by 100%.

So, we have:

$\%Percent = \frac{15}{105} * 100\%$

$\%Percent = \frac{15*100}{105}\%$

$\%Percent = \frac{1500}{105}\%$

$\%Percent = 14.3\%$ --- approximated
