I think you forgot to list the following.

Adding or subtracting fractions with different denominators
Bas_tet [7]

Step-by-step explanation: You can't continue on with the problem until the denominators are the same. So you need to find the LCD (Least Common Denominator). For example...

\frac{1}{2} +\frac{1}{3}  The LCD is six

\frac{1*3}{2*3}=\frac{3}{6} =\frac{1}{3}

\frac{1}{2}+ \frac{1}{3}= \frac{3}{6} +\frac{2}{6}

\frac{3+2}{6}= \frac{5}{6}

Hope this helps, have a BLESSED and wonderful day! :-)

Find the value of x need answer quick please I tried to make question worth more but I don’t know how :(
Ivan

In the figure we have three parallel lines cut by two transversals

The theorem stares:

If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.

Applying this theorem we have:

\frac{4}{x} =\frac{6}{5}

To solve for x we cross multiply

6x=20

Dividing both sides by 6 we have:

x=\frac{20}{6} =\frac{10}{3}  =3\frac{1}{3}

The second option x=3\frac{1}{3} is the right answer

Ella invested $2,700 in an account paying an interest rate of 5.4% compounded
Dmitry [639]

Answer:

<em>The account will take 7 years to reach a value of $4,020</em>

Step-by-step explanation:

<u>Compound Interest </u>

When it occurs interest in the next period is then earned on the principal sum plus previously accumulated interest.

The formula is:

{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Ella invested P=$2,700 in an account with an interest rate of r=5.4% (0.054) compounded monthly. Since there are 12 months in a year, n=12.

It will be calculated when will the account have a value of A=$4,020. Substituting all the values in the formula:

{\displaystyle 4,020=2,700\left(1+{\frac {0.054}{12}}\right)^{12t}}

Calculating:

{\displaystyle 4,020=2,700\left(1.0045)^{12t}}

Dividing by 2,700:

{\displaystyle \frac{4,020}{2,700}=\left(1.0045)^{12t}}

To solve this equation for t, we need to apply logarithms:

{\displaystyle \log\frac{4,020}{2,700}=\log\left(1.0045)^{12t}}

Applying the logarithm power rule:

\displaystyle \log\frac{4,020}{2,700}=12t\log 1.0045

Dividing by 12log 1.0045:

\displaystyle t=\frac{\log\frac{4,020}{2,700}}{12\log 1.0045}

Calculating:

t= 7.39 years

Rounding to the nearest year, the account will take 7 years to reach a value of $4,020

A college offers shuttle service from Dickson Hall or Lot B to its
marta [7]

Answer:

At 10:30 A.M.

Step-by-step explanation:

A college offers shuttle service from Dickson Hall or Lot B to its  campus quad.

At 9:10 A.M the first shuttle leaves from their locations for the campus.

If the shuttles leave from Lot B every 10 minutes and leave from Dickson Hall every 12 minutes, then both the shuttles will leave their origin at the same time after 60 minutes.

This is because 60 is the smallest multiple of 10 and 12 which is common for them.

Therefore, 10:30 A.M. is the next time when both shuttles will depart for the campus at the same time. (Answer)
