Answer:
the number of students enrolled this year is 21,600 students
Step-by-step explanation:
The computation of the number of students enrolled this year is as follows:
= Number of students enrolled last year × increased percentage
= 20,000 students × 108%
= 21,600 students
hence, the number of students enrolled this year is 21,600 students
The sum of angles in any Rhombus is 360 degrees.Opposite angles of a rhombus are congruent.
Two of the adjacent angles are 2x+20 and 50 degrees.
The opposite angles measure 2x+20 and 50 degrees.
Sum of angles in any Rectangle is 360
2x+20+50+2x+20+50=360
Adding line terms,
4x+140=360
Subtracting 140 both sides:
4x=220
Dividing both sides by 4
x=55
Option B. 55 is the right answer.
Answer: x=7
Step-by-step explanation:
8 + 4 = 2(x - 1) combine like terms on the left side
12 = 2(x -1) Distribute on the right side
12 = 2x - 2 Add 2 to both sides
+2 +2
14 = 2x Divide both sides by 2
x= 7
