sum = 2n + 3m
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
2*4 + 3*x = 34

to sum two numbers you add them together then to get twice that you multiply the sum by 2 e.g. if the two numbers are 5 and 8 the sum = 5 + 8 = 13 twice that is 13 x 2 = 26
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
2*n + 5 = 35
𝘛𝘸𝘪𝘤𝘦 means to multiply by 2. 𝘚𝘶𝘮 means to add together. So 𝘵𝘸𝘪𝘤𝘦 𝘵𝘩𝘦 𝘴𝘶𝘮 means to take whatever you're adding together and then multiply this result by 2. So your sum would be X+8. Multiplying this by 2 would give you 2X+16. Another way to write your answer would be to put parentheses around the X+8. That's because you need to do this part first. So another way to write your answer would be 2( X+8 ).
2a +16

"the sum of 2" and "twice" "a number" "is" "36"2+2x=36 â–
3x + (-4) ≥ 2x + 8
2*(n+3)
2n + (-5)
6*(13 + n)
Let's call the number XTwice the number would be 2XFour times the same number would be 4XThe sum of these two is 2X + 4X = 6XThe answer is therefore six times the number.
