30% of 250 can be written as 0.3 * 250:

0.3(250) = 75

30% of 250 is 75.  Is this what you mean by "compute with percents?"

taurus [48]

Answer: x=\frac{12}{7}

Step-by-step explanation:

Remember the logarithms properties:

log(m)-log(n)=log(\frac{m}{n})\\\\b^{log_b(a)}=a

Then,simplifying:

log_{8}(\frac{x}{-2x+4}) = log_{8}(3)

Apply base 8 to boths sides and then solve for "x":

8^{log_{8}(\frac{x}{-2x+4})}=8^{log_{8}(3)}\\\\\frac{x}{-2x+4}=3\\\\x=3(-2x+4)\\\\x=-6x+12\\x+6x=12\\7x=12\\\\x=\frac{12}{7}

Damon buys lumber worth $562. He gets a 20% contractors discount. The sales tax is 6%. His credit card gives him 2% off. How muc
Zanzabum

Answer:

$467.05

Step-by-step explanation:

By getting a discount of 20%, it means he pays 100-20=80% of the initial price

80% is same as 0.8

Price after discount will be

0.8*$562=$449.6

Taxation is then subjected to the discounted price. With tax rate of 6% which is equivalent to 0.06 then the total prive incurres will be 106% of the discounted price, same as 1.06

Final price inclusive of tax

1.06*$449.6=$476.576

Since his credit gives 2% discount of everytging then he only pays 98% of the price inclusive of tax

Payable amount

0.98*476.576=467.04448

Rounded off as $467.05

I need help with m-3 over 4 = m-3 over 5
MariettaO [177]
M=3

You would begin by cross multiplying and then solving it from there:

5(m-3)=4(m-3)
5m-15=4m-12
5m-4m=-12+15
m=3
