To simplify 2p + 7p, you first combine the like terms by adding the coefficients of the p variable. In this case, 2p + 7p is equal to 9p. Therefore, the simplified form of 2p + 7p is 9p.
To find the cost of 1 km of pipe at 7p for every 40cm, we first need to determine how many 40cm segments are in 1 km. There are 1000 meters in 1 km, so there are 1000/0.4 = 2500 segments of 40cm in 1 km. Multiplying this by the cost of 7p per segment gives us the total cost for 1 km of pipe, which is 2500 * 7p = 17500p.
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.
15 + 3 = 7p - 4p ie 18 = 3p so p = 6
It is: 11p+11 simplified
The variable is p.
To simplify 2p + 7p, you first combine the like terms by adding the coefficients of the p variable. In this case, 2p + 7p is equal to 9p. Therefore, the simplified form of 2p + 7p is 9p.
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
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
