3a+2b=8 \displaystyle a = 6b + 6 a=6b+6

Mathematics

First, let's write it like this:
3a+2b=8
Subtract 2b from both sides.
3a+2b-2b=8-2b
3a=8-2b
Divide both sides by 3.
\frac{3a}{3}=\frac{8-2b}{3}
a=\frac{8-2b}{3}

Now that we know what's the value of a, let's find the value of b
3\cdot \frac{8-2b}{3}+2b=8
Let's take the first part.
3\cdot \frac{8-2b}{3}
Multiply the fractions.
=\frac{\left(8-2b\right)\cdot \:3}{3}
Cancel the common factor, which is 3.
=8-2b
We would be left with.
=8-2b+2b
Add like terms.
=8
We would be left with.
8=8
Subtract 8 from both sides.
8-8=8-8
0=0

This tells us that b can be any number. 

Let me know if you need any help!
Thanks!

At a​ café, the cook uses a recipe that calls for eggs and milk. The amounts of eggs and milk have a proportional relationship.
DanielleElmas [232]

Answer:

Eggs    2               3              4

Milk      6               9             12

Ratio    3/1            3/1           3/1

Step-by-step explanation:

Look at the second column with 2 eggs and 6 cups of milk.

6 cups milk and 2 eggs. The ratio of the number of cups of milk to number of eggs is 6/2, which is the same as 3/1 in the second column. The number of cups of milk is always 3 times the number of eggs.

If you know the number of eggs, multiply by 3 to get the number of cups of milk. 3 * 3 = 9 in the third column.

If you know the number of cups of milk, divide by 3 to get the number of eggs. 12/3 = 4 in the fourth column.

Eggs    2               3              4

Milk      6               9             12

Ratio    3/1            3/1           3/1

In which question is r = -17 a solution?
devlian [24]

Answer:

None

Step-by-step explanation:

Simply solve each linear equation and get value of R.

Or another way can be to put value of R in all four options and find whether left hand side is equal to right hand side or not.

A) 3-\frac{2R}{4}=10

   -\frac{R}{2}=7

   R = -14

B)  \frac{3}{4}-2R =10

     -2R=10-\frac{3}{4}

    R = -37/8

C)  3(R-4)=10

     R-4=\frac{10}{3}

    R=4+\frac{10}{3}

  R = 22/3

D) 3-\frac{R}{4}=10

    R = -28

So, none of the option's are having solution R =-17.
