A = E
B = F
C = G
Look for the equation which has the same placement. Your answer should be B) BC=FG
10 to the 2nd power is 100 so that equation is saying 910 divided by 100 equals 9.1
Hope that helps
Answer: 18 years
Work Shown:
The steps above show f(x) replaced with 5. Then you'd use logarithms to isolate the variable x. The relevant useful log rule is so we can pull down the exponent.
From here it seems your teacher wants you to round up to the nearest integer.
If we plugged in x = 17, then f(x) = 4.99 which is one cent too small.
While x = 18 leads to f(x) = 5.19
Therefore, x = 18 has the price reach or exceed $5
Answer:
Let Jody's Age be X
Then Jody's Brother age is: 2x - 3
Total is: (2x - 3) + x = 30
Now we solve for x
2x - 3+ x = 30
3x - 3 = 30
3x = 30 + 3
3x = 33
x = 33/3
x = 11
Therefore the age of Jody's Brother is (2×11) - 3 = 19
