X = -2
y = 2
You can get this by setting the two different y's equal to each other and solving for the x value.
To find all the different possible combinations, you multiply all the possibilities for each position.
1st - she as 20 different possible buttons
2nd - she would have 19 possible buttons
3rd-she would have 18 possible buttons
20 x 19 x 18=6840 possible ways to choose these buttons.
Answer:
<u>The correct answer is that the rate of inflation is 2%.</u>
Step-by-step explanation:
<u>Real = nominal - inflation </u>
<u>Inflation = Nominal - Real</u>
<u>Inflation = 3% - 1% = 2%</u>
In general, the nominal quantities are those in «gross». Precisely, what the real magnitudes do is subtract the effect of inflation from the nominal magnitude. When speaking in real terms, it refers to base year prices. That is, a specific year is set as a reference and the prices of the base year of the products to be studied are taken. In this way, the effect of inflation is excluded in the studies. The process to convert a nominal value to real terms is precisely called inflation adjustment. And thanks to this adjustment, real values are an excellent measure of net purchasing power, regardless of price changes over time.
Triangle....
three angles<span> of any </span>triangle<span> have sum equals 180
</span>so
m<A + m<B +m<C = 180 then substitute values and solve for x
I can't see clearly on m<A...is it the value 35? if so
x+35+65 = 180
x+100 = 180
x = 180 -100
x = 80
Answer:
89–100
Step-by-step explanation:
Let x represent the grade on the fifth test. The average for 5 tests wants to be between 80 and 90, so we have ...
80 ≤ (78 +62 +91 +80 +x)/5 ≤ 90
Multiplying by 5 gives
400 ≤ 311 +x ≤ 450
Subtracting 311 gives the range for the fifth test grade.
89 ≤ x ≤ 139
Since the maximum available score is 100, the range on the 5th test for an overall B grade is ...
89 ≤ x ≤ 100 . . . . where x is the grade on the 5th test
