To find the value of X you would have to solve the equation.
Example: for question 2
Answer:
30 + 12y
Step-by-step explanation:
Width of the rectangle is given by (5+2y)
Length of the rectangle is twice its width.
= 2*(5+2y)
=10 + 4y
Perimeter of the rectangle is the sum of all four sides of the rectangle.
Hence perimeter is given by 2 * (length + width)
= ![\[2* [(5 + 2y) + (10 + 4y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%285%20%2B%202y%29%20%2B%20%2810%20%2B%204y%29%5D%5C%5D)
Simplifying,
= ![\[2* [(15+6y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%2815%2B6y%29%5D%5C%5D)
= ![\[(30+12y)\]](https://tex.z-dn.net/?f=%5C%5B%2830%2B12y%29%5C%5D)
Hence the perimeter of the rectangle is given by (30 + 12y)
5p+2r=q
Move variable to the right
5p=q -2r
Divide both sides of the
equation by 5
q - 2
p =— — r
5 - 5
The final solution for
p is
q - 2
p =— — r, rER, qER
5 - 5
I cannot make the E like it should be made in mathematics on this keyboard. An elongated E.
Answer:
802,000
Step-by-step explanation:
The number in the thousands place is 1, and the number to the right of it is 5. And if the number to the right is greater than or equal to 5 the place value that you are rounding goes up by one.
