Which of the following is equivalent to this expression
3(x-1)
A. 3+x+3-1
B. 3+x-1
C. 3x-3
D. 3x-1
3(x-1)
A. 3+x+3-1
B. 3+x-1
C. 3x-3
D. 3x-1
3(x-1)
= 3 * x - 3 * 1
= 3x - 3
Therefore, the correct answer is C. 3x-3
= 3 * x - 3 * 1
= 3x - 3
Therefore, the correct answer is C. 3x-3
Which of the following is not equivalent to this expression
2m +10m +14 +3
A. m+12m+8+9
B 2m+10+10m+7
C. 6m+6m-1+18
D 15m + 15-3m+2
2m +10m +14 +3
A. m+12m+8+9
B 2m+10+10m+7
C. 6m+6m-1+18
D 15m + 15-3m+2
2m +10m +14 +3
= 12m + 17
Let's try to simplify each expression and see if they are equivalent:
A. m + 12m + 8 + 9
= 13m + 17 (not equivalent to 12m + 17)
B. 2m + 10 + 10m + 7
= 12m + 17 (equivalent to 12m + 17)
C. 6m + 6m - 1 + 18
= 12m + 17 (equivalent to 12m + 17)
D. 15m + 15 - 3m + 2
= 12m + 17 (equivalent to 12m + 17)
Therefore, the expression in option A is not equivalent to 2m + 10m + 14 + 3 which is 12m + 17.
= 12m + 17
Let's try to simplify each expression and see if they are equivalent:
A. m + 12m + 8 + 9
= 13m + 17 (not equivalent to 12m + 17)
B. 2m + 10 + 10m + 7
= 12m + 17 (equivalent to 12m + 17)
C. 6m + 6m - 1 + 18
= 12m + 17 (equivalent to 12m + 17)
D. 15m + 15 - 3m + 2
= 12m + 17 (equivalent to 12m + 17)
Therefore, the expression in option A is not equivalent to 2m + 10m + 14 + 3 which is 12m + 17.
Which equation is equivalent to 4X +3+ (-3x) +7x-6x = 11
A. 8x+3=11
B. 2x+3=11
C. 5x=11
D. -4x=11
A. 8x+3=11
B. 2x+3=11
C. 5x=11
D. -4x=11
4X + 3 + (-3x) + 7x - 6x = 11
4X - 3x + 7x - 6x + 3 = 11
(4 - 3 + 7 - 6) x + 3 = 11
2x + 3 = 11
2x = 11 - 3
2x = 8
x = 4
Therefore, the equation equivalent to 4X + 3 + (-3x) + 7x - 6x = 11 is A. 2x + 3 = 11.
4X - 3x + 7x - 6x + 3 = 11
(4 - 3 + 7 - 6) x + 3 = 11
2x + 3 = 11
2x = 11 - 3
2x = 8
x = 4
Therefore, the equation equivalent to 4X + 3 + (-3x) + 7x - 6x = 11 is A. 2x + 3 = 11.
