It can be simplified to 30pqr which means the same as the given terms
Yes. 3 quarters and 2 pennies. 3Q = $0.75 2P = $0.02 = $0.77
2p + 3q = 13, 5p - 4q = -2 Multiply the first equation by 4 and the second by 3 and add them, which gets rid of the q: 8p + 15p = 52 - 6, and 23p = 46, so p=2. Plug that into the first equation to find q: 4 + 3q = 13, so q=3. Test your answers in the second equation to be sure: 5(2) - 4(3) = 10-12 = -2. It checks. So p=2, q=3.
6p + 11q + 4
3p+7 = 16+2p 3p-2p = 16-7 p = 9
3q + 2p
(3q + 2p)(9q + 7p)
3q 2p
P = 3a - 3q Add 3q to each side: P + 3q = 3a Double each side: 6a = 2P + 6q
2p = 4y - 12xy - 6x, 3q = 12 - 15y so 2p - 3q = 4y - 12xy - 6x - (12 - 15y) = 4y - 12xy - 6x - 12 + 15y = 19y -12xy - 6x - 12
-1P-6Q-4 would be the answer if the space between the 3P and the second 3Q is another subtraction symbol.
3q+11+8q>99
(4p - 1)(3q - 2)
It can be simplified to 30pqr which means the same as the given terms
3q + 2z, although it could be 2*(3q+z)
3q+4r-s+5q-6r+2s
To evaluate an algebraic expression means to simplify the expression as much as possible by replacing the variables in an expression with the numerical values given to you.Ex:Example of Evaluating an Algebraic ExpressionTo evaluate the algebraic expression '4.5 + x' for x = 3.2, we need to replace x with 3.2 and then add. 4.5 + x = 4.5 + 3.2=7.7Solved Example on Evaluating an Algebraic ExpressionEvaluate the algebraic expression p + 3q + 2p - 3q, for p = 2 and q = - 5.Choices:A. 12B. 18C. 3D. 6Correct Answer: DSolution:Step 1: p + 3q + 2p - 3q [Original expression.]Step 2: = (p + 2p) + (3q - 3q) [Group the like terms together.]Step 3: = 3p [Solve within the grouping symbols.]Step 4: = 3 x 2 [Substitute 2 for p.]Step 5: = 6 [Multiply.]
