A angle that is 171° will be in the 2nd quadrant
Answer:
4+2x is a sum.
Step-by-step explanation:
It can't be 1, because the coefficient of "x" is 2.
It can't be 2, because there aren't two variables in 4+2x. The only variable is x.
It can't be 4, because 4+2x is ADDING, not multiplying.
There we go!
Answer:
after 2 months the total cost will be the same.
Step-by-step explanation:
21+20x=27+17x subtract 17x on both sides because its the lowest coefficient
20x- 17x = 3x 17x-17x= cancel out
subtract 21 on both sides because its the lowest number
21-21= cancel out. 27-21=6
divide the coefficient by both sides
3x/3= x
6/3= 2
x=2
<span>The first group is 5 - 9, the second group is 10 - 14 and the third group is 15 - 19. We now find the number of data within the interval 15 - 19. In the given frequency distribution, 17, 15, 18, 19, 19 and 16 are within the interval 15 - 19. Therefore, the frequency of the third group is 6.</span>
