Answer:
x = infinite amount of solutions
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
3(x + 10) + 6 = 3(x + 12)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3: 3x + 30 + 6 = 3x + 36
- Combine like terms: 3x + 36 = 3x + 36
- Subtract 36 on both sides: 3x = 3x
- Divide 3 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>. We can plug in any number <em>x</em> and it would render the equation true.
∴ x = infinite amount of solutions
Answer:
95%
Step-by-step explanation:
95% *980 =931
Answer:The answer is 50
Step-by-step explanation:
The first step is to add up the numbers in order to get the outcome
5 red + 20 blue +25 green =5+20+25 =50
Step 2
Probability =no of events /no of outcome
We were asked to find the probability of red
Where red represent event
And the summation of red ,green and blue represents outcome .
So probability of red =5/50 = 1/10
Step 3
Recall in the question ,we were told that the card was selected 500 times ,so we multiply the probability of getting red by 500
1/10 *500 =50
Therefore the probability of drawing a red card from the special deck 500 times is 50 .
Answer:
Step-by-step explanation:
If all 21 coins were dimes, she'd have $2.10. But she has 90 more cents than that. Now for each coin that's a quarter, not a dime, she has 15 cents more. 90/15= 6. So there are 6 quarters, and 21-6 = 15 dimes.
Now we do it backwards to see if it's right. 6 quarters is $1.50, 15 dimes is $1.50, add those together and you get $3. So it's right. 6 quarters, 15 dimes.
10x+3 = 3x+24
10x-3x= 24-3
7x=21
X= 21/7
Final answer:
X=3
I’m not so sure of my answer but wish you the best and good luck!!
