Answer:
The value of x is equal to -2/3.
Step-by-step explanation:
In the problem it says that y equals 2x, and that 3x - 3y = 2.
The first step is to substitute 2x into y.
3x - 3(2x) = 2.
The next step is to use distributive property.
-3(2x) = -6x.
Now we need to add like terms.
3x - 6x = -3x.
Which gives us the equation -3x = 2.
The final step is to divide on both sides to get the value of x.
-3x/-3 = 2/-3.
x = -2/3.
So as you can see, x is equal to -2/3.
We can also check to make sure by redoing the problem, but substituting the value of x.
3(-2/3) - 3(2 * -2/3) = 2.
-2 - 3 * -4/3 = 2.
-2 + 4 = 2.
2 = 2.
The value of x is indeed -2/3.
Answer:
Area = 28 cm² (check the attached diagram for better clarity)
Step-by-step explanation:
The question is incomplete but let's see a similar example
The front of a rectangular pyramid can refer to either one of two possibilities: it could be either the side that has the breadth and the height or the side that has the length and the height. In this case, we were given the formula for calculating the area of the front face of this rectangular prism as the product of breadth and height
Mathematically,
A = bh
From the attached diagram, we will see the properties of the rectangular prism as:
length = 5 cm, breadth = 4 cm, height = 7 cm
To calculate for the front face, we use A = bh,
⇒ A = 4 * 7 = 28 cm²
Example 2
If the breadth of the rectangular prism is 2 cm and the height is 3 cm, we have:
A = 2 * 3 = 6 cm²
Do 8 divided by 1.6. that will give you the number of miles. this would be 5 miles
