Answer:
Option A: 3x + 5x - 4 = 1
Step-by-step explanation:
Given that:
3x + y = 1 ------------- eq1
y + 4 = 5x ------------ eq2
Now for substitution in eq1 we will get a value of y from eq2:
y = 5x - 4
Substituting in eq1 we get:
3x + 5x - 4 = 1

Median: The middle number in the data set when the
data set is written from least to greatest.
Since our data set is already written from least to greatest,
we can just look for the number that appears in the middle.
In this case, it would be 3.
Mode: The number that appears
most frequently in a data set.
Notice that the number 3 appears twice in the data set and no other
number appears more than once. So the mode is 3.
Range: The difference between the greatest number in
the data set and the least number in the data set.
Since the greatest number is 8 and the least number is 1,
the range of the data set will be 8 - 1 or 7.
Let the number = x.
48% of x = 108
(48/100)x = 108
x = 108 * 100 /48 = 225 use your calculator.
Answer is option C.
Hello :
13π/4 = (16-3)π/4
= 16π/4 -3π/4
13π/4 = -3π/4 +4π
tan( 13π/4) = tan ( -3π/4)= - tan ( 3π/4) =- tan( π - π/4) = - tan(- π/4)
tan( 13π/4) = -(-tan(π/4)) =tan(π/4)=1
