4(x-5) +2 =x+3 <br><br> I need help on this ! I don’t get it picture above !
algol [13]

Answer:

x=-5

Step-by-step explanation:

4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).

4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.

4x-18=x-3       Subtract x from each side. Now, we can get x to only one side.

<u>-x       -x</u>

3x-18=-3         Add 18 to both sides.

  <u>+18 +18</u>

3x=-15            Divide both sides by 3.

<u>/3   /3</u>

x=-5

I hope this helped you!! Have a great day c:

Use the figure below to find the missing sides and angles.
Sunny_sXe [5.5K]

Answer:

AC = BC = 5

AB = 5√2

∠A = ∠B = 45

∠A = 90

Step-by-step explanation:

AC = 5 ( Reason : 5 squares are present in between A and C )

Similarly,

BC = 5

<u>By Pythagoras theorem</u>,

(AB)² = (AC)² + (BC)²

        = 5² + 5²

        = 2 * 5²

(AB)² = 2 * 5²

AB = 5√2

Since, sides AC and BC are equal,

∠A = ∠B = 45

Since, AC is perpendicular to BC,

∠A = 90

1000 students participated in a survey on a university campus about their TV watching habits. All
nasty-shy [4]

Hi, you've asked an unclear question. However, I inferred you may want to know the actual number of students represented by the percentages of 27%, and 61%.

<u>Explanation:</u>

Finding percentage usually involves performing two operations; multiplication and division.

First, all (100%) of respondents said they watched TV at least at some point during the day.

Next, 27% of respondents stated that they only  watched television during prime time hours, in which the actual number of students represented by the percentage is calculated by dividing 27 by 100 and multiplying by 1000 =

\frac{27}{100} * 1000 = 270.

Finally, we are told 61% of respondents stated that they spend prime time  hours in their dorm rooms. The actual number of students represented by the percentage is calculated by dividing 61 by 100 and multiplying by 1000 =

\frac{61}{100} * 1000 = 610

The sum of a number, n, and a number 5 larger than it is 41.
lina2011 [118]

Answer:

36

Step-by-step explanation:

If you set the equation up, it would be n + 5 = 41. If you subtract the 5 from both sides to get n by itself, you get n = 36.
