This is a one-step equation. All you need to do is multiply the 2.5 over to the 20 to get x by itself.
x=50
Hope this helps!
4 days because he drinks 6 in two and 12 in 4 days.
The multi-stage fitness test (MSFT), also known as the beep test, bleep test, PACER (Progressive Aerobic Cardiovascular Endurance Run), Pime, they are cautioned. A second caution ends the test for that runner. The number of shuttles completed successfully is recorded as the score of that runner. The score is recorded in Level.Shuttles format (e.g. 9.5).
Answer:
40 copies for $3000
Step-by-step explanation:
First: The Equation
y=(20+x)(100-x)
This shows how for every new painting, the price will go down.
y=2000+80x-x²
Convert it to standard form: ax²+bx+c
You can now choose to graph it or find the vertex form. For the limit of time, I will just use a graph.
The vertex, (40,3000), is your answer, where the x value is the number of paintings and the y value the money made.
Answer:
1
Step-by-step explanation:
sin²x = (sinx)²
cos²x = (cosx)²
Step 1: Define
sin²45° + cos²45°
Step 2: Rewrite
(sin45°)² + (cos45°)²
Step 3: Evaluate
sin45° = √2/2
cos45° = √2/2
(√2/2)² + (√2/2)²
1/2 + 1/2
