Answer:67
Step-by-step explanation:
Answer:
x= -5
Step-by-step explanation:
Add 5 to both sides
-3x -5+5 = 10 +5
-3x = 15
Divide both sides by -3.
-3x/-3= 15/-3
x= -5
which one ?
the bottom or the top or is this a trick
We can express this number in the standard form, which is simply 15xyz+10xy+5x. Alternatively, we can factor a 5 or an x out, receiving 5(3xyz+2xy+x) or x(15yz+10y+5). However, the most effective factorization is to factor out 5x, for a result of 5x(3yz+2y+1).

6 pachages
each pcage has 30
6*30=180 total
17 left over
how many used
used=total-left over
used=180-17
used=163
16. xy is 2 digit number
multiplules of 10 (whole multipules) always end with 0 so y=0
and has 3 as one of its factors
factors of 3 is 3,6,9,12
30,60,90 is answer
17.
30 in 9 parks
30 times 9
30=10 times 3
3*10*9
group the 3 and 9
10*(3*9)
3*9=27
10*(27)
270
15. 163
16. 30,60,90
17. see above, 270
