10% of what is 9...
0.10x = 9
x = 9/0.10
x = 90.....he has 90 all together
Answer:
the vertex is at (3,17)
it opens downward
the axis of symetry is x=3
Step-by-step explanation:
let me know if you need more info than that.
Hope this helps! :)
6:5
- there are 165 counters in the bag.
let the white counter be x
2x + x = 165
divide both sides by 3
there are 55 white counters in the bag
165-55=110
OR
2x= 165
divide both sides by 2
x= 110
- there are 110 black counters in the bag
- Martine takes 40%of the black counter
40%= 40/100×110
= 44.
- 44 black counters was taken out of the bag
- then there would be 66 black counters left I.e(110-44=66)
▪︎ there would be 66 black and 55 white counters in the bag.
- ratio of black counters to the white counter = 66:55
- reduced to the lowest term = 6:5 ( 11 divides 66 and 55 Into 6 and 5)
• the answer is 6:5
