Answer:
A. 2y = 22
Step-by-step explanation:
You are basically combining like terms. Look at the equation and subtract from top to bottom.
You will subtract 5x and 5x, 4y and 2y, and 25 and 3.
Now you have 0 + 2y = 22.
Removing the 0 (because it is worth nothing), you will be left with 2y = 22 which corresponds to A.
Answer:
y = 2x - 5
y = -x + 1
Step-by-step explanation:
y = 2x - 5
y = -x + 1
the systems have one solution
=> (2, -1)

Answer: 0.235</h3>
======================================================
Explanation:
9 yellow
9 red
9+9 = 18 total
If you select a marble at random, the chances of it being yellow are 9/18.
If you selected another marble at random, without replacing the first marble, then 8/17 is the probability of getting another yellow marble. I subtracted 1 from the numerator and denominator of 9/18 to go to 8/17.
We multiply the two results
(9/18)*(8/17) = 0.235 approximately
There's roughly a 23.5% chance of getting two yellow in a row, where we don't replace the first marble selected.
Answer:
13 040 000
Step-by-step explanation:
To convert the scientific notation of a large number to a decimal number, move the decimal point as many places to the right as indicated by the exponent of 10.
Use zeros for placeholders as needed.
Move the decimal point seven places to the right
1.304 × 10⁷ = 13 040 000
We had to insert four zeros as placeholders.
1.304 × 10⁷ = 13 040 000
