99 X 99 X 99 / 9 - 99 /99 PLEASE EXPLAIN ;)
charle [14.2K]

Answer:

107810

Step-by-step explanation:

You can use the order of operations! So we start with 99^3/9. That is 99^2*11. So now let’s do 99/99, it’s 1. So 99^2*11 is 107811, so the answer is 107810.

13x-11 +18x15+ 4x+1=180°
BARSIC [14]

Answer:

x = - 80/17, or x = - 4 \frac{12}{17}

Step-by-step explanation:

13x-11 +18×15+ 4x+1=180°

<=> (13x + 4x) + (18×15+ 1 - 11)=180°

<=> 17x + 260 =180

<=> 17x = 180 - 260

<=> 17x = - 80

<=> x = - 80/17

<=> x = - 4 \frac{12}{17}

DENIUS [597]

<u>Answer:</u>

<u>Step-by-step explanation:</u>

Its true that if there is no linear equation to start with, you can isolate and substitute a variable that is squared in both the equation.

For example, for the given non linear equation, start by dividing both sides by coefficient of the variable.

Once you do that and isolate a variable, continue solving by substituting that variable into the other equation.
