What is the value for "a"?

Mathematics

Answer:

Step-by-step explanation:

The question is a bit ambiguous. I believe that you are not adding 6 to 3 to get nine.

The only other choice would be 3*3 = 9

So a should 9 * 3 = 27

15 multiplied by 3 = 45

90 divided by 3 = 30

36 * 3 = 108

Answer:

9

Step-by-step explanation:

if 9/3 = 9

then 27/3 = 9

135/15=9

90/10 = 9

36/4 = 9

since all is equal to 9

a=9

Hope this helps

Find the solution of the system of equations.<br> – 2 – 8y = -30<br> 2x + 8y = 36
nydimaria [60]

Answer:

x= 1.5

y= 4.125

Step-by-step explanation:

Step one:

given the two equations

-2x - 8y = -30-------1\\\\2x + 8y = 36--------2

Step two:

let us subtract the equations

-2x - 8y = -30-------1\\\\ -(2x + 8y = 36)--------2\\\\0x-16y=-66

-16y=-66\\\\16y=66

divide both sides by 16

y=66/16\\\\y=4.125

put y= 4.125 in equation 2

2x + 8(4.125)= 36\\\\2x+33=36\\\\2x=36-33\\\\2x=3\\\\x= 3/2\\\\x= 1.5

Bad White [126]
First, we need to add up all the quantities in ounces. 10 + 14 + 40 = 64. One pound = 16 ounces. 64 / 16 = 4, so the total weight in pounds is 4 lbs.
