Answer:
x = 3, y = 2
Step-by-step explanation:
Substitute the values of x from each alternative in the previous <em>question</em>, then solve for y. This is depicted below.
- <em>A. y = -7, x = 5, 4(5) + 2y + 3 = 19</em>
- <em>B. y = 0 and x = 4, 4(4) + 2y + 3 = 19</em>
- <em>C. y = 2 and x = 3, 4(3) + 2y + 3 = 1</em>
- <em>D. y = 4, x = 2, 4(2) + 2y + 3 = 19</em>
Only the third option has a y value that is <em>comparable</em> to the value in the computations, according to the calculations.
As a result, the letter C is the correct response.
A=5 4/7 or 5.57142857143
I cannot be simplified any more
2x +100=16+4x
-2x. -2x
100=16+2x
-16. -16
84=2x
divide both sides
x=42
Answer:
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.
