You need to add the second number and the answer to get your answer
A. 2
B.6
D.5
F.4
G. 3
Answer:
If your saying estimate this number in a decimal without calculators I think I might be able to help as illustrated below:
Step-by-step explanation:
2 5/6 shows that the whole number will be a 2. The 5/6 is a decimal below one as it is not one whole fraction. This means that we have to estimate the value of 5/6 and add that value to the number 2. 1/3 is a common fraction that is equal to about 0.33. This is because 0.33 + 0.33 + 0.33 is almost 1, which means 1/3 of one is indeed equal to 0.33.
<u>This means we divide 0.33 by 2, because that would be equal to (1/3)/(2), or 1/6. </u>0.33/2 seems like it would be 16.5. 16.5 * 5, as in 5/6, would be 82.5.
I would then say that the estimate of 2 5/6 is 2.83.

Answer:
x^2+2x -6
Step-by-step explanation:
f(x)=2x+1
g(x)=x^2-7
(f+g)(x)= 2x+1+x^2-7
Combine like terms
= x^2+2x -6
9 x 5 - 3 x 1
45 - 3 = 42
answer: 42
