HELP ME PLEASEEE!!!!!!! I am stuck

Mathematics
1 answer:
NISA [10]4 years ago
8 0

Answer:

X = 62

Step-by-step explanation:

The inside of a triangle is always equal to 180º therefore, you need to add everything up to equal 180. It should look like

(x + 1) + 55 + x = 180

Now you just solve.

Since there are 2 x's you can combine the like terms making them equal 2x

Now the equation should look like 2x + 1 + 55 = 180

Simplify the other like terms: 2x + 56 = 180

Now you want to get x by itself so you subtract 56 from both sides:

2x + 56 = 180

    -56      -56

------------------------

2x = 124

Now to finish getting x by itself, divide both sides by 2.

2x = 124

-----   ------

2         2

x = 62

FINALLY you plug in x to see if it worked.

(62 + 1) + 55 + 62 = 180

Find (-21)+(-13)+20.
Fed [463]

Answer:

14

Step-by-step explanation:

-21+-13+20=14

This is true because when subtracting negatives by negatives you pretty much add them and then when you add a positive to a negative you are technically removing the negative by the amount you are adding.

In short its kind of like using inverse operation in a way.

Hope this helps and have a nice day

Also may I please have a brainliest!!!

If a=[-2 -4 2 5 1 5 -1 -3 -4] and b=[2 3 -5 5 -4 2 -1 -1 3] find ba
Shalnov [3]

The product of A and B matrix will be option D; BA = \left[\begin{array}{ccc}16&10&39\\-32&-30&-18\\-6&-6&-19\end{array}\right].

<h3>What is the multiplication of matrix?</h3>

If A = \left[\begin{array}{ccc}-2&-4&2\\5&1&5\\-1&-3&-4\end{array}\right]and B = \left[\begin{array}{ccc}2&3&-5\\5&-4&2\\-1&-1&3\end{array}\right]

then,

BA = \left[\begin{array}{ccc}2&3&-5\\5&-4&2\\-1&-1&3\end{array}\right] \left[\begin{array}{ccc}-2&-4&2\\5&1&5\\-1&-3&-4\end{array}\right]

BA = \left[\begin{array}{ccc}16&10&39\\-32&-30&-18\\-6&-6&-19\end{array}\right]

Hence, the product of A and B matrix will be option D; BA = \left[\begin{array}{ccc}16&10&39\\-32&-30&-18\\-6&-6&-19\end{array}\right].
