PLEASE HELPPPPPP!!!!!!Solve this system of linear equations separate the x-and y-values with a comma
GenaCL600 [577]

Answer:

x=-6,\\y=6

Step-by-step explanation:

Rewrite the system of equations as:

\begin{cases}-13x+2y=90\\-6x+2y=48\end{cases}

Subtract the second equation from the first to isolate x:

-13x+2y-(-6x+2y)=42,\\-7x=42, \\\fbox{$x=-6$}

Plug in x=-6 into any of the equations above and solve for y:

-6(-6)+2y=48,\\2y=12,\\\fbox{$y=6$}

Verify that the solution pair (-6, 6) works \checkmark

Therefore, the solution to this system of equations is:

x=-6,\\y=6

Find the perimeter of the following triangle. Round your answer to the nearest hundredth.
vladimir2022 [97]

Step-by-step explanation:

step 1. The perimeter (P) is the length around the triangle.

step 2. P = 6 + 5 + L (the length of the hypotenuse)

step 3. L = sqrt(6^2 + 5^2) = sqrt(61) where sqrt is the square root

step 4. P = 11 + sqrt(61) = 18.81.

PLEASSSEEE ELXPLAIN THE ANSWER I REALLY NEED HELP ON THIS
Mashutka [201]

Answer:

It will take him <u>20 days</u> to read a 300-page book.

Step-by-step explanation:

Given:

Stephen read a 90-page book in 6 days.

If he continues reading at that rate.

Now, to find the time it will take him to read a 300-page book.

So, we solve using unitary method:

If, Stephen read 90 pages in 6 days.

So, Stephen read 1 page in = \frac{6}{90} days.

Thus, Stephen read 300 page in = \frac{6}{90} \times 300

=\frac{1800}{90}

=20\ days.

Therefore, it will take him 20 days to read a 300-page book.
