Answer:

x = -9

Step-by-step explanation:

I'm sorry, but I won't be explaining it, however I will show every step.

Let's begin.

4x - 12 = -7x - 111

4x - 12 + 7x = -7x - 111 + 7x

11x - 12 = -111

11x - 12 + 111 = -111 + 111

11x + 99 = 0

11x + 99 - 99 = 0 - 99

11x = -99

11x/11 = -99/11

x = -9

Answer:

40287600 = B. 4 x $10^{7}$

Step-by-step explanation:

<u>We first have to do the multiplication of the numbers given:</u>

19 * 2,120,400

=> 40287600

<u>Now we have to figure out how many digits are after the number 4:</u>

4, 0 2 8 7 6 0 0

7 digits

Meaning that we need an exponent of 7 for it to be in scientific notation, giving us with the answer B. 4 x $10^{7}$

Please help me solve them

deff fn [24]

Ok so the first thing to do would be get rid of the fraction. To do that multiply the ENTIRE equation but the denominator. Once all the numbers are multiplyed I think it’ll be easier for u to solve them :) or if u wanna solve them quick, download Photomath :)
