Answer:
b = 4
Step-by-step explanation:
3 - b = 6 - 7
3 - b = -1
-b = -1 -3
-b = -4
b = 4
The answer to that question is the sum of the hours he studied for on both days, which will be 1/4 + 3/8.
However, we cannot add fractions with different denominators. In this case, it's 4 and 8.
So if we want to add them, we must make the denominators similar to each other. How to make 4 into 8? We multiply it by 2: 4 x 2 = 8.
BUT when we multiply fractions, we must multiply both the numerator and the denominator by the same number to keep its original value. In this case, if you want to multiply 4 by 2, you must also multiply 1 by 2.
=> SO to make 1/4 into y/8, we will multiply it like this (1 x 2) / (4 x 2) = 2/8
Now we can add the 2 fractions together. 2/8 + 3/8 = (2 + 3)/8 = 5/8. THIS IS YOUR ANSWER.
TL;DR: He studied 5/8 (or 0.625) hour altogether on both days.

(We know this from a=1/9 and r=3)
Simplifying this, we get:

Since we're finding the first term that exceeds 1000, let's set it equal to 1000.

Multiplying both sides by 27


n≈9.2
We have to round n up, since if n=9, the value would be <1000.
Therefore n=10. Substituting n=10,

=2187
Therefore the first term that exceeds 1000 is 2187, and it is the 10th term
Step-by-step explanation:
okay I think you can solve this question
Answer:
Subtract 20 from both sides.
24−20=9/g
2 Simplify 24-20 to 4
4=9/g
3 Multiply both sides by 9
4×9=g
4 Simplify 4×9 to 36
36=g
5 Switch sides.
g=36
