If you would like to write 0.85 in a fractional notation, you can do this using the following steps:
0.85 = 85/100 which simplifies to 17/20 <span>(the common factor of 85 and 100 is 5, so you
can divide both numbers by 5).
The correct result would be 17/20.</span>
Answer:
Step-by-step explanation:
Find the sum of the first 42 terms of the following series, to the nearest integer.
2,7,12
Solution
The sum is given by
SUM_n=n/2*(a_1+a_n)
a_n=a_1+(n-1)d
a_1=2, n=42, d=5
The 42nd term is therefore given by
a_42=2+(42-1)5=207
SUM_42=42/2*(2+207)=21*209=4389
The sum of the first 42 terms of the series, therefore, is 4389
Simplify: 12(2 + 3x - 6)
= (12)(2 + 3x + - 6) = (12)(2) + (12)(3x) + (12)( - 6)
= 24 + 36x - 72
Answer = 36x - 48
2: Factor:
36x - 48
= 12(3x -4)
Answer
= 12(3x -4)
3: <span>12(2+3x−6)
= 12(3x + 2 - 6)
= 12(3x - 4)
Your Answer would be (A).
3x - 4</span>
Answer:
2) 
3) 5√2
Step-by-step explanation:
Simplest radical form of an expression is the expression in radical so that there are no more square roots, cube roots, 4th roots, etc left to find, after rationalising the denominator ( if needed ).
2. Here the given expressions,

For rationalising the denominator multiply both numerator and denominator by √11,

3. given expression,




Answer:
y =
x + 8
Step-by-step explanation:
The equation of a line in slope- intercept gorm is
y = mx + c
Given
3x - 2y = - 16 ( subtract 3x from both sides )
- 2y = - 3x - 16 ( divide all terms by - 2 )
y =
x + 8 ← in slope- intercept form
