Hey there!

\large\textsf{11t - 6t = 45}

\huge\textsf{COMBINE the LIKE TERMS}

\large\textsf{(11t - 6t) = \bf 5t}

\large\textsf{NEW EQUATION: 5t = 45}

\huge\textsf{DIVIDE 5 to BOTH SIDES}

\mathsf{\dfrac{5t}{5}=\dfrac{45}{5}}

\large\textsf{CANCEL out: }\mathsf{\dfrac{5}{5}}\large\textsf{ because that gives you 1}

\large\textsf{KEEP: }\mathsf{\dfrac{45}{5}}\large\textsf{ because that helps solve for the t-value}

\mathsf{\bold{t} = \dfrac{45}{5}}

\huge\textsf{SIMPLIFY \&  YOU HAVE YOUR ANSWER}

\mathsf{\dfrac{45}{5}=\bf 9}

\boxed{\boxed{\huge\textsf{Answer: t = \bf 9}}}\huge\checkmark

\large\textsf{Good luck on your assignment and enjoy your day!}

A rectangular portrait has an area of 40 square feet it's perimeter is 26 feet what are the dimensions of the portrait?
lana [24]

Answer:

Step-by-step explanation:

Portrait is in the shape of a rectangle.

And the area of a rectangle = Length × Width

Let the length of the portrait = l

And width of the portrait = w

Area of the portrait = lw

lw = 40

l = \frac{40}{w}

Perimeter of a rectangle = 2(Length + width)

Perimeter of the portrait = 2(l + w)

26 = 2(l + w)

l + w = 13 ----------(2)

By substituting the value of 'l' in equation (1) from equation (2)

\frac{40}{w}+w=13

40 + w² = 13w

w² - 13w + 40 = 0

w² - 8w - 5w + 40 = 0

w(w - 8) - 5(w - 8) = 0

(w - 5)(w - 8) = 0

w = 5, 8 feet

From equation (2)

l = 8, 5 feet

Therefore, dimensions of the portrait are (5 feet by 8 feet) Or (8 feet by 5 feet).

The table shows the values of different measurements in the metric system.
Lunna [17]

A micrometer has a power of 10^{-6}

A millimeter has a power of x 10^{-3}

A nanometer  has a power of 10^{-12}

A picometer  has a power of 10^{-12}

We are to write the numbers in standard form.

Standard form is a way of writing simplifying numbers and expressing numbers to a power of 10.

For example, to express 1000  in standard form, count the number of digits after the first number. There are 3 zeros. 3 would be the power of the number. So, 1000 in standard form is 1 x 10³

To express a decimal in standard form, count the numbers of zeros and the first non-zero digit  The negative of the number would be the power.

For example, 0.001 is standard form is 1 x 10^{-3}

A micrometer has 6 digits after the decimal point , it power would be x 10^{-6}

A millimeter has 3 digits after the decimal point, its power would be x 10^{-3}

A nanometer has 9 digits after the decimal point, its power would be x 10^{-12}

A picometer has 12 digits after the decimal point, its power would be x 10^{-12}
