Answer: x = -6

Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.

y = x - 6

y = 2x

2x = x - 6 (substitute the y value into the equation)

1x = -6 (subtract x on each side)

x = -6 (1x is basically saying x so you do not need to divide)

You multiply the length of the model car by the meters from the actual car. It’s easier to convert one unit of measurement to match with the other. I found it easier to convert 18.2 cm to meters which is 0.182 m. Now we multiply 0.182m by 0.3m to get the length of the actual car.

The answer would be 0.0546m. Or if you prefer centimeters, then the answer would be 5.46 cm. Either way is fine.

Hope this helped, please let me know if I was correct. :D

Solve the equation 3x-2y =7, x+2y= -3

swat32

Answer:

x=1
y= -2

Step-by-step explanation:

3x-2y =7
x+2y= -3
4x=4
x=4/4
x=1
3x-2y=7
3(1)-2y=7
3-2y=7
-2y=7-3
-2y=4
2y=-4
y=-4/2
y= -2
Verify solution
x+2y= -3
1+2y= -3
2y=-3-1
2y= -4
y= -4/2
y= -2

Each person would get $\frac{5}{8}$ pizza.

Solution:

Total quantity of pizza = $1\frac{7}{8}$

Number of persons shared = 3

To find how much pizza would each person get:

Let us first convert improper fraction into mixed fraction.

$$1\frac{7}{8}=\frac{1\times8 + 7}{8}=\frac{15}{8}$

Now divide the total quantity of pizza by the number persons shared.

$$\text{Quantity of pizza each person get}=\frac{(\frac{15}{8}) }{3}$

$$=\frac{15}{8\times3}$

$$=\frac{15}{24}$

Divide both numerator and denominator by 3.

$$=\frac{15\div3}{24\div3}$

$$=\frac{5}{8}$

Quantity of pizza each person get = $\frac{5}{8}$

Hence each person would get $\frac{5}{8}$ pizza.
