Answer:
1/4
Step-by-step explanation:
multiply the whole number to the denominator
so 4(2) = 8
u now have 2/8
simplify the fraction and ur done :)
in decimal form .25
Answer:
12.25
Explanation
49/20 <em><u>(which is the same as (</u></em><em><u>4</u></em><em><u>9</u></em><em><u>÷</u></em><em><u>2</u></em><em><u>0</u></em><em><u>))</u></em><em><u> </u></em>=2.45
<em><u>Multiply</u></em><em><u> </u></em><em><u>2</u></em><em><u>.</u></em><em><u>4</u></em><em><u>5</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>amount</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>hours</u></em><em><u> </u></em><em><u>(</u></em><em><u>5</u></em><em><u>)</u></em><em><u> </u></em>

=12.25
Answer:
We have: 2x+7y=−1
Let’s express this equation in terms of y:
⇒y=−27x−17
⇒ Gradient =−27
Parallel lines always have the same gradient:
⇒ Gradient of parallel lines =−27
Perpendicular lines have the negative reciprocal of the gradient:
⇒ Gradient of perpendicular lines =72

The value of x is -9 and 3.Option D.
Step-by-step explanation:
Given,

To find the value of x.
We will apply middle term factor formula.
The given equation can be written as,

or,
+(9-3)x-27 = 0
or, x²+9x-3x-27= 0
or, x(x+9)-3(x+9)=0
or, (x+9)(x-3) = 0
So, x = -9 and x = 3
Hence,
The correct option is Option D.
