Answer: A.30
Step-by-step explanation:
Let's solve your equation step-by-step.
8x−3(2x−4)=3(x−6)
Step 1: Simplify both sides of the equation.
8x−3(2x−4)=3(x−6)
8x+(−3)(2x)+(−3)(−4)=(3)(x)+(3)(−6)(Distribute)
8x+−6x+12=3x+−18
(8x+−6x)+(12)=3x−18(Combine Like Terms)
2x+12=3x−18
2x+12=3x−18
Step 2: Subtract 3x from both sides.
2x+12−3x=3x−18−3x
−x+12=−18
Step 3: Subtract 12 from both sides.
−x+12−12=−18−12
−x=−30
Step 4: Divide both sides by -1.
−x/-1 = -30/-1
<h3>x=30</h3>
8^2+15^2=x^2
64+225=x^2
289=x^2
Hypotenuse=17
Answer: $5100
Step-by-step explanation:
Use the rule of logarithms:
log(a)-log(b)=log(a/b)
log(65--log(x)=log(39)=log(65/x)
=> 39=65/x =>
x=65/39=5/3
Answer: A
Step-by-step explanation:
So we really just want to find when y=-3.
We can see this is at x=5, meaning our answer is A.
