6x+ (1/2x)(y)=3

Step 1: Factor out variable x.
x (y+12/2)=3

Step 2: Divide both sides by (y+12/2.

x(y+12/2)         3
------------- = ---------
   y+12          y+12
-----------      ----------
      2                2

Then your answer would be            6
                                              x=  ---------
                                                      y+12

Richard is 6 years older than Lisa, and in 5 years the sum of their ages will be twice as much as the sum of their ages 4 years
natta225 [31]
If we assume that Lisa is x years old, then Richard will be (x + 6)years
In 5 years time
Lisa = x +5 years
Richard = x +11 years
sum will be 2x + 16 years
4 years ago
Lisa = x-4 years
Richard = x + 2
Sum will be 2x - 2
 Therefore;
2(2x-2) = 2x +16
4x -4 = 2x +16
      2x = 20
        x = 10 
Thus, the present age of Lisa is 10 years and that of Richard is 16 years

4x + 3y = 1<br> x - 3y = -11
JulijaS [17]

Answer:

(- 2, 3 )

Step-by-step explanation:

Given the 2 equations

4x + 3y = 1 → (1)

x - 3y = - 11 → (2)

Adding the 2 equations term by term will eliminate the y- term

5x + 0 = - 10

5x = - 10 ( divide both sides by 5 )

x = - 2

Substitute x = - 2 into either of the 2 equations and solve for y

Substituting into (1)

4(- 2) + 3y = 1

- 8 + 3y = 1 ( add 8 to both sides )

3y = 9 ( divide both sides by 3 )

y = 3

solution is (2, - 3 )

sammi is trying to wrap a gift for her brother. the gift fits into a cube-shaped box with a side length of 9 inches. how many sq
Flauer [41]

Answer:

A=486\ \text{inches}^2

Step-by-step explanation:

The area of a cube shaped box is given by :

A=6s^2

Where

s is the side length and A is the surface area

We have, s = 9 inches

So,

A=6\times (9)^2\\\\A=486\ \text{inches}^2

So, the required area is 486\ \text{inches}^2.
