Answer 3

1/4y - 3 = 9
1/4y = 9 + 3
1/4y = 12
y = 12 x 4
y = 48

Answer 4

Thank you!!!!

Answer 5

can you help me with more lupita?

Answer 6

Step one is to get your variable alone. So you will add 3 to both sides of the equation. \[\frac{ 1 }{ 4 }y=12\] Next step would be to multiply both sides by 4 to get your Y alone. \[y=48\] Hope I helped!

Answer 7

your welcome yes i can

Answer 8

3/4(x-12)=3

Answer 9

Multpliy both sides of the equation by (4/3), the reciprocal of (3/4)

x=12*(4/-3)=(48/3)=(16)

x=(16)

Hope this helps.

yes

Answer 12

4/9n+6=4/3

Answer 13

4/9n + 6 = 4/3

What you need to do first is to get 6 to the other side. The first step to do that is to have 6 and 4/3 have a common denominator.

6 turns into 18/3 because 18 divided by 3 is 6. So now that you've got common denominator you can subtract six on both sides..

4/9n +18/3 - 18/3 = 4/3 -18/3

Once you simplify you should come up with..

4/9n = -14/3

Now you have to divide 4/9 to both sides..

Now, when you divide fractions, you have to multiply by the reciprocal ( which is the fraction flipped upside down. For example, the reciprocal of 1/2 would be 2/1), like so:

-14/3 ÷ 4/9 ----> -14/3 x 9/4

Once you do that, you get -42/4, which simplifies to -21/2, or -10.5

Answer 16

1. -3/10+A=2/5
2. 12+0.35x=20.05
3. 0.6(y + 3) = 4.8

Answer 17

number 2. Simplifying
12 + 0.35x = 20.05

Solving
12 + 0.35x = 20.05

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12' to each side of the equation.
12 + -12 + 0.35x = 20.05 + -12

Combine like terms: 12 + -12 = 0
0 + 0.35x = 20.05 + -12
0.35x = 20.05 + -12

Combine like terms: 20.05 + -12 = 8.05
0.35x = 8.05

Divide each side by '0.35'.
x = 23

Simplifying
x = 23

Answer 18

number 3 Simplifying
0.6(y + 3) = 4.8

Reorder the terms:
0.6(3 + y) = 4.8
(3 * 0.6 + y * 0.6) = 4.8
(1.8 + 0.6y) = 4.8

Solving
1.8 + 0.6y = 4.8

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-1.8' to each side of the equation.
1.8 + -1.8 + 0.6y = 4.8 + -1.8

Combine like terms: 1.8 + -1.8 = 0.0
0.0 + 0.6y = 4.8 + -1.8
0.6y = 4.8 + -1.8

Combine like terms: 4.8 + -1.8 = 3
0.6y = 3

Divide each side by '0.6'.
y = 5

Simplifying
y = 5
