Duration of time passed is given by
The scroll is old.
Answer:
521.
Step-by-step explanation:
143
+ 378
= 521
Working from right to left:
First add the 3 and 8 = 11
write 1 underneath
and carry the other 1 to the second column.
1 +4+7 = 12. Write 2 and carry the 1 to the first column.
1 + 3 + 1 = 5.
Answer 521.
X+1 is the answer for this question
Y = 1/3x + 2
Explanation- find the slope. By looking at the first point, you go up 1 and over 3, making slope 1/3. Or you can find the slope with the equation:
m = y2-y1
———
x2-x1
The y intercept is on the y axis at 2.
So, The equation is y = 1/3x + 2
The solution to the equation is (b) there is no solution.
<h3>How to solve the rational equation?</h3>
The equation is given as:
Factorize the quadratic numerator
Multiply through by (x - 1)(x - 2)
2x(x - 2) - (2x -5) = -3(x - 1)
Expand
2x² - 4x - 2x + 5 = -3x + 3
Collect like terms
2x² - 4x - 2x + 3x + 5 - 3 = 0
Evaluate the like terms
2x² - 3x + 2 = 0
Using a graphical tool, the above equation has no real solution
Hence, the solution is (b) there is no solution.
