Add -6 to both sides

square root x+6-6=7+-6

square root x=1

Solve square root

square root x=1

x= 1^2 ( square root both sides )

x=1

I hope that's help !

The answer is 1 because in 1st step we subtract 6 on both side and we get x=1 and square root of 1 is 1 itself

A car travelled a distance of D =320 kilometers for T =5.0 hours at a constant rate use the formula D =R. T To find the speed (R

motikmotik

The speed of car is 64 kilometer per hour

Solution:

Given that car travelled a distance of D = 320 km for T = 5.0 hours

To find: speed (R) of the car in km per hour

Formula given:

D = R. T

where "D" is the distance

"R" is the speed of car

"T" is the time taken

Substituting the given values in above formula we get,

$320 = R \times 5.0\\\\R = \frac{320}{5}\\\\R = 64$

Thus the speed of car is 64 kilometer per hour

We cannot round the answer to nearest tenth, since answer is not in decimal

4. Four friends went on a trip to Mexico. They rented a car for eight days which cost

nlexa [21]

Explanation:

So, I know a lot of people won't do it this way, but this is how I would do it.

First, multiply each expense by eight (eight for the eight days)

$55 x 8 = 440

$25 x 8 = 200

$129 x 8 = 1032

Next, take the three answers and add them together:

440 + 200 + 1032 = 1672

Lastly, divide 1672 by four (four for the four friends)

1672/4 = 418

There you go! Here is your answer. Each friend paid $418

Hope I helped! :D

You need 10,000 to pay for your final college tuition. you find a loan it is compounded quartely at 6.25% for 10 years. how much

$\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$10000\\
r=rate\to 6.25\%\to \frac{6.25}{100}\to &0.0625\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{quarterly, thus four}
\end{array}\to &4\\
t=years\to &10
\end{cases}
\\\\\\
A=10000\left(1+\frac{0.0625}{4}\right)^{4\cdot 10}
\\\\\\
A=10000(1.015625)^{40}\implies A\approx 18592.39366677226890$
