50% - .5
7/15 - .46
the remote control car
I'm kind of in a rush, the answer is 72!
7x+1 + 4x-3 = 42
11x-2=42
11x=44
Divide by 11 on both sides which equals:
x=4
To find the length of DE just plug 4 in for x into the equation:
(7x+1) —> 7(4)+1= 29
29 is the length of DE
Then plug in 4 to EF’s equation:
(4x-3) —> 4(4)-3=13
13 is the length for EF
29+13= 42
So in the end, your answer will be 29.
If it doubles in every 4 months, then in 1 year it will double by 12/4 = 3 times.
So, the expression would be: n³
n = number of rabbit at starting point = 8
So, after 1 year, it would be = 8³ = 512
So, your final answer is 512
Hope this helps!
