Solve. −3.5=−4.6x−5.1 Enter your answer as a fraction in simplest form in the box.
Law Incorporation [45]

Answer:

<u>x = 8/23</u>

Step-by-step explanation:

<u>Adding 3.5 to each side</u>

  • -3.5 + 3.5 = -4.6x - 5.1 + 3.5
  • -4.6x - 1.6 = 0

<u>Adding 4.6x to each side</u>

  • -4.6x - 1.6 + 4.6x = 0 + 4.6x
  • 4.6x = -1.6

<u>Dividing each side by 4.6</u>

  • 4.6x/4.6 = -1.6/4.6
  • <u>x = 8/23</u>

Roger's Cafe has usual daily earnings of $800. Today, the cafe earned 120% of the usual daily earnings. How much did they earn t
riadik2000 [5.3K]

Answer:

960

Step-by-step explanation:

Over here, I'm going to do it in two ways, and either way works, one is just easier to do out:

1st way:

You can represent the percent 120 as a decimal which is 1.20, then you do 800*1.2.

2nd way:

You can use benchmark percents. You find 10 percent of 800 which is 80 and multiply 80 by 2 to get 160, so 20% is 160 dollars. Then you add 160 to 800 (800+160) and get 960.

Please tell me if you have any questions.
