Answer:
A:B:C = 5:5:7 or 5x : 5x : 7x
Cindy ate 30 Skittles less than Ann and Ben together
-----> 7x = 5x + 5x - 30
-3x = -30
x = 10
5x = 50
7x = 70
They ate 50+50+70 = 170 of them
Answer:
ok so c is 5 + 1. that is 6. and d is 3 x 5 which is 15 + 6, so 21. I dont know about a or b though, sorry.
Step-by-step explanation:
The rule starting with five. 5 marbles in first line.
Every consecutive line has a number that is four less than twice the previous line.
marbles in second line = 2(marbles in first line) - 4
So the number of marbles in second line = 2(5) -4 = 10-4 = 6
marbles in third line = 2(marbles in second line) - 4
So the number of marbles in second line = 2(6) -4 = 12-4 = 8
marbles in fourth line = 2(marbles in third line) - 4
So the number of marbles in fourth line = 2(8) -4 = 16-4 = 12
marbles in fifth line = 2(marbles in fourth line) - 4
So the number of marbles in fifth line = 2(12) -4 = 24-4 = 20
marbles in sixth line = 2(marbles in fifth line) - 4
So the number of marbles in sixth line = 2(20) -4 = 40-4 = 36
36 marbles must be in the sixth line.

According to the Question,
<h3>From the Question,</h3>
- Initial Acceleration,a = 5 m/s²
- Force at a = 5 m/s²,f = 25 N
- Final Acceleration,A = 9 m/s²
<h3>To find</h3>
Force exerted on the object at a = 9 m/s²
We Know that,
Firstly,we need to find the mass of the object
Thus,
Now,
