If 1,600 people live 25% of the population how many people need to leave

Mathematics
1 answer:
Zolol [24]3 years ago
7 0
Please, proofread your problem statements before posting them.  Your "If 1,600 people live 25% of the population how many people need to leave" should be written as "<span>If the whole population is 1,600 and 25% of them need to leave, how many must leave?"

0.25(1600) = 400

400 people need to leave.  This is 25% of the entire population, or 25% of 1600 people.   Please note:  it's "leave," not "live."</span>

3x + y = – 7<br> Solve to find were the two point intercept
Tju [1.3M]

Answer:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>
  • First we need to convert it into y=mx+c form

{:}\longrightarrow\sf 3x+y=-7

{:}\longrightarrow\sf y=-7-3x

  • Now create table using this
<h3><u>Table</u><u>:</u><u>-</u></h3>

\boxed{\begin{array}{|c|c|c|c|} x & 1 & (-1) & 0 \\ y & -10 & (-4) & -7 \end{array}}

Hence the intercepts are

\therefore\sf A (1,-10),B(-1,-4),C(0,-7)

Complete the sequence<br> 0.428. 0.447, 0.466,
Nadusha1986 [10]

Answer:

0.485

Step-by-step explanation:

Each term is 0.019 more than the term before it.

Therefore to find the next term, we just need to add 0.019 to the last given term:

0.466 + 0.019 = 0.485

The next term is 0.485.

Hope this helped!

What is the result of subtracting the second equation from the first -2x+7y=10 3x+7y=2
Iteru [2.4K]

The answer after subtracting the following equation is x= -8/5

Step-by-step explanation:

  • -2x+7y=10 ----- eq(1) , 3x + 7y =2------ eq(2)

  • 7y+3x =2
  • 7y-2x = 10
  • subtracting eq 2 from eq 1 we get
  • 5x = -8
  • x= -8/5
