"Starting with three, every consecutive line has 2 less than twice the previous line."
this statement means that
your staring line has 3 marbles. You multiply the 3 marblesby 2 so
3x2=6
And then you minus it by 2
6-2=4
which means that you'll get 4 marbles for the next line.
So to get your 6th line, you count how many marbles is on the 5th line but since your diagram doesn't have the 5th line you have to figure out the 5th line by counting how.many marbles is on the 4th line.
4th line = 10 marbles
10×2=20
20-2=18
5th line = 18
18×2=36
36-2=34
So the 6th line has 34 marbles.
Answer:
0.4 liters of juice and 400 mL
Step-by-step explanation:
divide 2/5=0.4 and multiply 0.4x1000=400
Answer:
2nd option
Step-by-step explanation:
Repeatedly divide by 2 until the value 1 is reached
32 ÷ 2 = 16
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
2 ÷ 2 = 1 ← finish here
Then
32 = 2 × 2 × 2 × 2 × 2
First equation
L.H.S = 4x -0.25y
so it doesn't equal the R.H.S
2nd equation
R.H.S = 15q + 3qr
so it doesn't equal the L.H.S
3rd equation
R.H.S = -30m -60n
so R.H.S doesn't equal L.H.S
4th equation
L.H.S = -16a +4
so L.H.S equal R.H.S
The answer is D
