I would say the correct answer is 1728.
The figures are increasing by half each week. To calculate the figure for the 11th week you could use this sum: 20×1.5^11
20 is the starting figure. 1.5 is the multiplying factor to get the figure for the next week and the 11 is the number of weeks.
I hope this helps.
Answer: 2/3
First, you have to add all of the counters to get the denominator (bottom number). 5+3+1=9. The number of blue counters is 5+1 (red+yellow)=6. Then use the fraction 6/9. Then, simplify to get 2/3.

Answer:
3y
Step-by-step explanation:
To write an expression, define variable. x will be "another number". This means "one number that is 1/3" is 1/3 * x.
1/3 x represents the smaller number.
To represent the larger number, use the inverse or reciprocal. y will be the smaller number. The larger number will be 3*y or 3y.
Answer:
If the original equation is y - 5 - - 2(x+3), then y = -2x-1
If the original equation is y-5 = 2(x+3), then y = 2x +11
Step-by-step explanation:
Slope intercept form is y=mx+b
If the equation is y-5 - -2(x+3) = 0, then
y-5 +2(x+3) = 0
y-5+2x+6 = 0
y+1 +2x = 0
y = -2x - 1
If the equation is y-5 = 2(x+3), then
y - 5 = 2x + 6
y = 2x + 11
