Answer:
x = 32
Step-by-step explanation:
∠BCA = ∠DBA (90 - ∠DBC)
∠A = ∠A
ΔABD similar to ΔACB
AC/AB = AB/AD
x / 8 = 8 / 2
x = 32
Answer:
y = 5 * (3^x)
Step-by-step explanation:A scientist begins an experiment with a culture of 5 bacteria cells.
Every hour, the number of bacteria cells triples.
Which equation can be used to represent the number of bacteria cells, y, as it relates to time in hours, x?
:
I think it would be y = 5 * (3^x)
Answer:
19
Step-by-step explanation:
I just googled it lol
1. 3x+8+4x+10=8x
2. 7x+18=8x
3. 18=x
maybe there is a glitch in the system... i have worked the equation more than 5 times... there is no other solution. i suggest u ask ur teacher for assistance, to make sure u are correct.
Good luck!
Answer:Step 1. Turn the second fraction (the one you want to divide by) upside down (this is now a reciprocal).
Step 2. Multiply the first fraction by that reciprocal
Step 3. Simplify the fraction (if needed)
Example:
1/2 ÷ 1/6
Step 1. Turn the second fraction upside down (it becomes a reciprocal):
1/6 becomes 6/1
Step 2. Multiply the first fraction by that reciprocal:
1/2 x 6/1 = (1x6) / (2x1) = 6/2
Step 3. Simplify the fraction:
6/2 = 3
