Answer:
15
Step-by-step explanation:
15 can go into 90, 6 times. It is neither a multiple of 6 or 9. It is larger than 10 and smaller than 20.
2/3 = x/(3x + y)
Cross multiply:
3x = 2(3x + y)
Distribute 2:
3x = 6x + 2y
Subtract 6x to both sides:
-3x = 2y
Divide 'y' to both sides:
-3x/y = 2
Divide -3 to both sides:
x/y = -2/3
Answer:
cos^-1(.17) is 1.40 in radian
Step-by-step explanation:
Given cos^-1(.17), the equivalent is 80.212
This is approximately 80.21°
Which is 1.40 in radian
Answer:
13x + 14
Step-by-step explanation:
5x + 6 + 3x = 8x + 6.
8x + 6 + x + 1 + x + 1 + 2= 10x + 10
10x + 10 + (2²)(i think) = 10x + 14
10x + 14 + 3x = 13x + 14
final answer
