there are 230 bags of bolts in the box because with 12 bolts per bag, you divide the total number of bolts by the number per bag to get the number of bags :)
Answer:
3:4
Step-by-step explanation:
(1/7)/(4/21) = (1/7)×(21/4) = 3/4 = 3:4
189
You can replace the values of x with 9 and the values of y with (-3).
7(2x-3y) = 7(2 × 9 - 3 × -3)
= 7(18 - -9)
= 7(18+9)
= 7 × 27
= 189
2.9 per second
- 4/6, -6/9, -8/12, -10/15, -12/18, -14/21, and more
