Answer:
<h3>
Therefore total amount of money that he got is = $(5+0.50x) [ x = number of correct math]</h3>
Step-by-step explanation:
Given, Gilberto's grandfather gives him $5 for his birthday and then$0.50 for each math he answers correctly on his math exam for the year.
Let , the number of math that he answers correctly on his his math exam for the year is x
Therefore he got = $(0.50× x) =$ 0.50x for doing correct math.
Therefore total amount of money that he got is = $(5+0.50x) [ x = number of correct math]
This can be solved by Newton's binomial formula
Tk+1 = (n k) a∧(n-k) b∧k k+1=7 => k=6, n=11 , a=-3x and b=-2y
T7= (11 6) (-3x)∧(11-6) (-2y)∧6 = (11*10*9*8*7)/(1*2*3*4*5) (-3x)∧5 (-2y)∧6
T7= 462 (-3x)∧5 (-2y)∧6
The correct answer is A.
Good luck!!!

Answer:
60%
Step-by-step explanation:
5+3+12=20
20 = 1/5 of 100
12 x 5 = 60
- 47 → d
using the ' product rule '
(uv) = uv' + vu' = (3 × - 4) + (7 × - 5 ) = - 12 - 35 = - 47
