You multiply 3/4 by 3/3 to get the dominator of 12 and get 9/12 then 1/3 by 4/4 to get the denominator of 12 and get 4/12 . Now that you have a common denominators you simplify 4/12 to 1/3 bc you divided 4/12 by 4 bc 4 is the greatest you can divide from. So Rob needs 1/3 cups of butter

5^(2x-1)+5^(x+1)=250 how do you solve? thank you

zepelin [54]

Answer:

x = 2

Step-by-step explanation:

Exponential Equations

Solve:

$5^{2x-1}+5^{x+1}=250$

Separate each exponential:

$5^{2x}5^{-1}+5^{x}5^{1}=250$

Operating:

$\displaystyle \frac{5^{2x}}{5}+5^{x}5=250$

Multiplying by 5:

$5^{2x}+25\cdot5^x=1250$

Rearranging:

$5^{2x}+25\cdot5^x-1250=0$

Recall that:

$5^{2x}=(5^{x})^2$

$(5^{x})^2+25\cdot5^x-1250=0$

Calling

$y=5^{x}:$

$y^2+25y-1250=0$

Factoring:

$(y-25)(y+50)=0$

There are two possible solutions:

y=25

y=-50

Since

$y=5^{x}$

y cannot be negative, thus:

$5^{x}=25=5^2$

The solution is:

x = 2

Can someone please help me am failing

Elena-2011 [213]

Part A: W= Wage (money earned)
$6 (earned per hour without working overtime) Equation: W=$6x
x= number of hours

S= (money earned)
$6 plus $9 (earned per hour with working overtime) Equation S=$15y
y= hours

Part C: Use S=$15y (this shows the amount of money earned after working overtime after the certain amount of hours spent)

$330=$15y

I think you can solve from there

Lee watches TV for 2 hours per day. During that time, the TV consumes 150 watts per hour. Electricity costs (15 cents)/(1 kilowa

shutvik [7]

So electricity costs 15cents every 1,000 watts used, and if he watches tv for 2hrs every day for a month that’s 60 hours (2*30) And every hour he watches tv it’s 150 watts. They want you to do the 60 hrs times 150watts which is 9,000 (amount of watts he uses in the month) and remember 1,000 watts is 15cents
