If a positive integer, list the values of x which satisfy the equation 3x - 4 < 6 and x - 1 > 0
{1, 2, 3}
{2, 3}
{2, 3, 4}
{2, 3, 4, 5}
Correct answer is B
3x - 4 < 6 = 3x < 6 = 4
3x < 10
x < \(\frac{10}{3}\)
x < 3.33 and x - 1 = 0
n > 1 = 1< x; since x is an integer, and 1 < x3.33
x = {2, 3}
solve \(\frac{2x + 1}{6} - \frac{3x - 1}{4}\) = 0
1
\(\frac{1}{5}\)
-\(\frac{1}{5}\)
-1
Correct answer is A
\(\frac{2x + 1}{6} - \frac{3x - 1}{4}\) = 0
\(\frac{4(2n + 1) - 6(3x - 1)}{24}\) = 0
-10x + 10 = 0
-10x = -10
x = \(\frac{-10}{-10}\)
x = 1
\(\pi\)cm
2\(\pi\)cm
3\(\pi\)cm
6\(\pi\)cm
Correct answer is A
Length of arc = \(\frac{\theta}{360} \times 2\pi r\)
= \(\frac{60}{360} \times 2\pi \times 3cm\)
= \(\pi\)cm
2cm
20cm
200cm
2000cm
Correct answer is B
1 litre = 1000cm3
1800 litre = 1800 x 1000cm3
l x b x h = capacity
600 x 150 x h = 1800000
h = \(\frac{1800000}{600 \times 150}\)cm
h = 20cm
If 85% of x is N3230, what is the value of x?
N2745.50
N3714.50
N3800.00
N4845.00
Correct answer is C
85% of x = 3230
\(\frac{85}{100} \times x\) = N3230
x = \(\frac{100}{85}\) x N3230
x = N3800.00
