Answer:
X = 9.5 + m
Step-by-step explanation:
m = money spent
x = money you had at the beginning
x = 9.5 + m
Substitute m in for 3.4
X = 9.5 + 3.4
Solve for x
X = 12.9
You started with $12.90
Answer:
x=±√7
Step-by-step explanation:
Hi there!
We're given the quadratic equation 6x²-42=0 and we need to find the roots of the equation (the values of x that make the equation true).
So we need to isolate x onto one side.
We can start by adding 42 to both sides
6x²=42
divide both sides by 6
x²=7
Now, take the square root of both sides (remember that when we take the square root, we get both POSITIVE and NEGATIVE answers).
x=√7 and x=-√7 (can be rewritten as x=±√7)
Hope this helps! :)
Algebra 1 is a basic algebra course usually taken in freshman year (9th grade). Common Core guidelines dominate the curriculum. It is faster paced than middle school math courses. Algebra 2 is a more advanced algebra course usually taken in junior year (11th grade). Algebra 2 is paced even faster and builds on what you learn in A1 and geometry. Both deal with variables and the manipulation of numbers.
Answer:
$109.45
Step-by-step explanation:
On Monday in the morning you worked 4 hours, so plug in the equation.
12.50(4)= $50
On Monday in the afternoon you worked 4 hours and 45 min
12.50(4) = $50
Then do 12.50/60 to get .208 ≈ .21
So 45(.21) = $9.45
50 +50 + 9.45= 109.45
