The variable is p.
2p+7p = 9p simplified
The answer is 17,500pHere's how I worked it out:1km - 10,000cm10,000cm divided by 40cm =250cm70p x 250cm = 17,500p
15 + 3 = 7p - 4p ie 18 = 3p so p = 6
It is: 11p+11 simplified
7p
The variable is p.
Seven multiplied by the variable "p"
4p + 9 + (-7p) + 2 = 4p - 7p + 9 + 2 = -3p + 11
7p + 2 = 5p + 8 7p - 5p = 8 - 2 2p = 6 p = 3
If A is a variable then it is a/2 which can also be expressed as A divided by 2.
4p + 9 - 7p + 2 4p - 7p + 9 + 2 p(4 - 7) + 9 + 2 -3p + 11
7p+2 is an algebraic expression. Since it is neither an equation nor an equality, it cannot have a solution or answer.
7p
5p + 15p + 7p = 27p 5p - 15p + 7p = -3p 5p x 15p + 7p = 75p2 + 7p 5p/15p + 7p = 7p + 1/3
4p+9-7p+2 -3p+11 p = 11/3
Collect like terms together: 4p + 9 + 7p + 2 = (4p + 7p) + (9 + 2) = (4 + 7)p + 11 = 11p + 11 = 11(p + 1)
7p-10p = -3
