Answer:
Pi/3 radians also measures 60 degrees not 30
Step-by-step explanation:
Pi/3 x 180/pi=180pi/3pi
Since both have pi they cancel out leaving 180/3, which equals 60.
In 1625 CE, a monument was found in Chang'an in China that records the history of the Christian religion in China. The monument dates from 781 CE. Christianity had its beginnings in Rome, which was almost 5,000 miles away. How might the monument have gotten there?
Idk what the dollar signs or what the letters represent, would help but doesnt make sense
Answer:
x = 2
y = -3
Step-by-step explanation:
Step 1: Write systems of equation
8x + 7y = -5
x = -3y - 7
Step 2: Solve for <em>y</em>
- Substitute 2nd equation into 1st: 8(-3y - 7) + 7y = -5
- Distribute 8: -24y - 56 + 7y = -5
- Combine like terms: -17y - 56 = -5
- Add 56 to both sides: -17y = 51
- Divide both sides by -17: y = -3
Step 3: Solve for <em>x</em>
- Substitute <em>y</em> to find <em>x</em>: x = -3(-3) - 7
- Multiply: x = 9 - 7
- Subtract: x = 2
Step 4: Check
<em>Plug in x, y into an original equation to verify it's a solution.</em>
2 = -3(-3) - 7
2 = 9 - 7
2 = 2
