To solve for the x, distribute first the numerical coefficients to the terms on the parentheses. This becomes,
7x - 21 = 4x + 20
Transpose all the terms with x and the constant on either sides of the equation,
7x - 4x = 20 + 21
3x = 41 ; x = 41 / 3
Thus, the answer is x = 41/3 which is fourth among the choices.
Answer:
Step-by-step explanation:
The area of a "simple" quadrilateral, like a square or a rectangle, is its width times its height: A=wh. The formula may fail for more complicated quadrilaterals.
Consecutive even integers..x, x + 2, x + 4
x + (x + 2) + (x + 4) = 6216
3x + 6 = 6216
3x = 6216 - 6
3x = 6210
x = 6210/3
x = 2070
x + 2 = 2070 + 2 = 2072
x + 4 = 2070 + 4 = 2074 <===house 3
Answer:
$39.95
Step-by-step explanation:
Thus, a product that normally costs $799 with a 5 percent discount will cost you $759.05, and you saved $39.95. You can also calculate how much you save by simply moving the period in 5.00 percent two spaces to the left, and then multiply the result by $799 as follows: $799 x . 05 = $39.95 savings.
Hello :)
We know that an answer in square feet would require us to calculate the area. In order to calculate the area of a rectangle, we multiply the length times the width. So, we have 6 x 2 which is 12 Therefore, the area is 12 square feet.

6+6+2+2=16
Have a nice day :)
