Answer:
x = 11
Step-by-step explanation:
and check:
If there are 27 students in the class and they have to form as many groups of 4 as possible, you can calculate this using the following step:
27 / 4 = 6.75 = 6 3/4
Result: 27 students can form 6 groups of 4 students and 3 students have to form their own group.
Step-by-step explanation:
take into 2 sections
-5<a-4 and a-4<2
-1<a and a<6
therefore it should be the 2nd one
The answer for this are (10,2), (8,1), and (14,-1).
It is isosceles trapezium, so angle A=angle B,
angle C=angle D=angle BDC
triangle BCD,
180=22 +D+(D-88)
(D-88) because in trapezium C=D, angle BCD=ACD-88 or C-88, and D-88
180=2D-66
2D=180+66
2D=246
D=123
