If your question is: How much is each print. The answer is 20 cents each
Answer:
x = 2
Step-by-step explanation:
Step 1: Write out equation
2 - 4x = 3x - 12
Step 2: Add 4x on both sides
2 - 4x + 4x = 3x + 4x - 12
2 = 7x - 12
Step 3: Add 12 on both sides
2 + 12 = 7x - 12 + 12
14 = 7x
Step 4: Divide both sides by 7
14/7 = 7x/7
2 = x
Step 5: Rewrite
x = 2
Area of the shaded region = Area <span>of a square - Area of a circle
</span>
Side of a square = 2r
Area of a square = (2r)² = 4r²
Area of a circle = πr²
Area of the shaded region = 4r² - πr² = r²(4-π)
Answer:
2x2x2x2x3
Step-by-step explanation:
Answer:
3.93 (approx.)
Step-by-step explanation:
3 ^ x + 6 = 3 ^ 4 can be rewritten as 3 ^ x = 3 ^ 4 - 6, or
3^x = 81 - 6 = 75.
Then 3^x = 75, or
x*ln 3 = ln 75
Solving for x:
x = (ln 75) / (ln 3) = 3.93 (approx.)
