Answer:
21/5 =x
Step-by-step explanation:
5x + 7 - x - 2 = 6x + 3x – 16
Combine like terms
4x +5 = 9x - 16
Subtract 4x from each side
4x+5 -4x = 9x-4x-16
5 = 5x-16
Add 16 to each side
5+16 = 5x-16+16
21=5x
Divide each side by 5
21/5 = 5x/5
21/5 =x
Answer:
a=11°
b=12°
Step-by-step explanation:
106°+ 7a-3°= 180°
7a= 180°-106°+3°
7a = 77°
a=77/7
a=11°
106° = 9b-2°
108°=9b
108/9 =b
b=12°
Answer:
shape V -----> 90° counterclockwise
shape II ------> 90° clockwise
shape III -----> translation
shape IV -----> 180° rotation
The six sided die has 6 sides (with numbers 1,2,3,4,5 and 6). That's why the probability to roll number 2 in one trial is equal to

.If you'll dol 50 trials, then you can expect

times to roll number 2 (8 or 9 times).
