Answer:
6x
Step-by-step explanation:
Combining like terms is simply representing them as a single term. With algebra, you can perform arithmetic on the coefficient (the 10 and the 4) to simplify the expression, giving you 6x.
A. 38
Let X = seventh graders
6th graders are twice the number of 7th graders; therefore, 6th graders will be 2X.
The total number of students is 57.
2X + X = 57
3X = 57
X = 57 / 3
X = 19
IF X represents the 7th graders; there are 19 seventh graders present.
Since 6th graders are represented by 2X; Then, 2 * 19 = 38 is the number of 6th graders present.
Add both numbers to check: 19 + 38 = 57.
you first have to simfly in the partithies always then solve and prove done!
