Answer:
Your answer is 17.5
Step-by-step explanation:
Turn your fraction into a decimal
2/5 = 0.4
Next multiply my given answer by 0.4
17.5 x 0.4 = 7
Therefore 17.5 is your final answer
So you know he starts off with 19. This is the first term. He learns one more each week, so let’s assign this the variable w.
19+1w
Set this equal to 47, since you’re solving how many to get to 47 recipes.
19+1w=47
To find out how many weeks, isolate the variable. Begin by combining like terms. Move the 19 to the side of the 47 by subtracting.
19+1w=47
-19 -19
—————-
1w= 28
To further isolate w, divide both sides by 1. This removes the coefficient from w and isolates it.
1w=28
—- ——
1 1
w=28
This means it will take him 28 weeks to learn 47 appetizer recipes in total. To check this answer, simply plug it back into the original equation.
19+1(28)=47
19+28=47
47=47
This means the answer is right, it will take 28 weeks.
I hope this helps! Please comment if you need any more explanation and I’ll get back to you ASAP.

Answer:
C
Step-by-step explanation:
Y=8x + 0.25
For i=1 ===> Sum=4
for i=2===> Sum=2
for I=3===> Sum=1
Hence the answer is 7
Or you could have use the Sum formula of a GP:
Sum = a(1-r)^n/(1-r), with a=1, r=1/2 & n=3
