Simplify \(\frac{m}{n} + \frac{(m - 1)}{5n} = \frac{(m - 2)}{10n}\) where n \(\neq\) 0
\(\frac{m - 3}{10n}\)
\(\frac{11m}{10n}\)
\(\frac{m + 1}{10n}\)
\(\frac{11m + 4}{10n}\)
Correct answer is B
\(\frac{m}{n} + \frac{(m - 1)}{5n} - \frac{(m - 2)}{10n}\); \(\frac{10m + 2(m - 1) - 1(m - 2)}{10m}\)
= \(\frac{10m + 2m - 2 - m + 2}{10n}\)
= \(\frac{10m + 2m - m - 2 + 2}{10n}\)
= \(\frac{11m}{10n}\)
The graph represents the relation y = xo2 - 3x - 3. Find the value of x for which x2 - 3x = 7
-1.55, 4.44
1.55, -4.55
-1.55, -4.55
1.55, 4.55
Correct answer is A
x2 - 3x = 7
x2 - 3x - 7 = 0
What can you add to both sides of the equation to give the same value of y = x2 - 3x - 3
The number is 4
x2 - 3x - 7 + 4 = 4
x2 - 3x - 3 = 4
but y = x2 - 3x - 3
y = 4; So are y = 4 draw a line parallel to x axis, to cut or intersect the graph. At these points look down to see the corresponding values on x axis
This give -1.55 and 4.55
Factorize the expression: am + bn - an - bm
(a - b)(m + n)
(a - b)(m - n)
(a + b)(m - n)
(a + b)(m + n)
Correct answer is B
am + bn - an - bm am - an - bm + bn a(m - n) - b(m - n) (a - b)(m - n)
0.46m
0.60m
0.87m
1.80m
Correct answer is B
volume of cylinder = \(\pi r^2\)h
0.216\(\pi\) m\(^3\) = \(\pi \times r^2 \times h\)
Since r = h,
0.216 = r\(^3\)
r\(^3\) = 0.216
r = \(\sqrt[3]{0.216}\)
= 0.6
