70 = 7 x 2 x 5
60 = 2² x 3 x 5
50 = 2 x 5²
LCM = 2 x 3 x 5 x 7 = 210
Answer: LCM = 210
Answer:
7
Step-by-step explanation:
Since, M is between S and T.
Therefore, SM + MT = ST
9x- 8 + 2x + 3 = 72
11x - 5 = 72
11x = 72 + 5
11x = 77
x = 77/11
x = 7
Answer:
-2
Step-by-step explanation:
8 (-2x + 1) = 30 - (-4 + 3x) Distribute
-16x + 8 = 30 + 4 - 3x Combine like terms
-16x + 8 = 34 - 3x Rearrange terms
-13x = 26 Divide by -13 on both sides
x = -2
The correct answer is 2 3/4
Answer: Option D
D.
; 
Step-by-step explanation:
We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.
We also know that a total of $ 880 was paid last month
To write an equation that represents this situation, let us call "d" the number of days that Barry attends school
So the cost was:

Now we solve the equation for the variable d



Therefore answer is the option D
