Answer:Okay I'm really confused
Step-by-step explanation:
Answer:
960 metres in 240 seconds.
Step-by-step explanation:
this is because they can run 4 metres every second.
the number of seconds they ran multiplied by the length of their run in a second is your answer.
240 x 4 = 960
Question:
2x + y = 3, x - 2y = –1.
If equation one is multiplied by 2 and then the equations are added, the result is _____.
(A) 3x = 2
(B) 3x = 5
(C) 5x = 5
Answer:
Option C:
5x = 5
Solution:
Given equations are
2x + y = 3 – – – – (1)
x – 2y = –1 – – – – (2)
Let us first multiply equation (1) by 2, we get
(1) × 2 ⇒ 4x + 2y = 6 – – – – (3)
Now, add equation (3) to equation (2).
⇒ x – 2y + 4x + 2y = –1 + 6
Combine like terms together.
⇒ x + 4x – 2y + 2y = –1 + 6
⇒ 5x = 5
So, if equation one is multiplied by 2 and then the equations are added, the result is 5x = 5.

Answer: y = -1x + 2</h2>
Step-by-step explanation:
Points ( -3,5 )( 6,-4 )
You use the slope formula to find the slope.
<h3>Note: You'll need to learn the slope formula to make more sense of it, I suggest watching a video about it.</h3>
M = Y2 - Y1 over
X2 - X1
Which is -4 - 5
6 - -3 = -9/9 = -1
The slope is -1
Now to find the y-intercept we use one of the x,y points ( I'll use 6,-4 )
And plug them in
-4 = -1(6) + b
-4 = -6 + b
+6 +6
2 = b
The equation will be y = -1x + 2
Since there are 12 months in a year, you would divide 3%, which is 0.3 converted to decimal, by 12
0.3 divided by 12 = 0.025
To round that answer by the nearest hundredth, you would look at the last digit.
Since that digit is a five, your rounded answer would be 0.03
ANSWER: 0.03%
