3. I am collecting baseball cards. My goal before I turn 18 is to have 500 cards. When I tumed 10,
vladimir2022 [97]

Based on the scenario given, the equation to describe the situation will be: c + 125 + 89 = 500 and 286 cards need to be collected.

Number of cards given by grandfather = 125 cards

Number of cards that will be given by father = 89 cards

Therefore, based on the information given, the equation to describe the situation will be:

c + 125 + 89 = 500

Therefore, we can then use the equation to calculate the number of cards that need to be collected. This will be:

c + 125 + 89 = 500

c + 214 = 500

c = 500 - 214

c = 286

Therefore, the person needs to collect 286 cards.

Simplify the following expression.<br> log(9x^5) + 5 log (1/x)
Darya [45]

Answer:

log9

Step-by-step explanation:

hello :

note :  a>0 and b>0

1) log(ab) = loga+logb

2) loga^n = nloga.....n in N

log(9x^5) + 5 log (1/x) = log(9x^5) +  log (1/x)^5 = log((9x^5) (1/x)^5)

                                 = log(9x^5)/(x^5)) = log9  because : (1/x)^5 = 1/x^5

Oksana_A [137]

Answer:

Marcus spent $6.36.

Step-by-step explanation:

First off, the fact that tax is included makes it easier for you, you don't need to worry about any multiplying!

Alright, so, he bought 2 candy bars for $0.79 EACH - that's 2 * $0.79 = $1.58.

Next, a drink for $1.49 and a bag of chips for $3.29. That's $1.49 + $3.29 = $4.78.

Now you add those two numbers up: $1.58 + $4.78 = $6.36.

Therefore, Marcus spent $6.36!
