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
Answer:
Step-by-step explanation:
Part A : when comparing graphs : A system of equations will have no solutions (on a graph) when your lines never cross each other. They never cross each other because your lines are parallel.
Part B : by comparing each algebraic equation : A system of equations will have no solution if your lines are parallel. Parallel lines will have the same slope but different y intercepts. Example :
2x - y = 2
4x - 2y = 8
put both equations in slope intercept form
y = 2x - 2
y = 2x - 4
they both have the same slope of 2.....and the y intercepts are different....meaning they are parallel lines and have no solutions
a: 47/44=3
3/2=1.5
b: (40*50 - 3*50)/40=46.25
