Answer:
a.) Let the total number be : x
∴(73.7÷x) ×100 = 55%
∴x= (73.7×100) ÷ 55
=> 7370÷55
∴x=134
Thus, Option-A.
----------------------------------------------------
b.) Let the percentage be : x
∴x= (46÷65) ×100
∴x= (0.707) × 100
∴x=70.7%
Thus, Option-B.

Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
Since you know m = 2, you can plug it into the equation
y = mx + b
y = 2x + b
To find "b", plug in the point (2,4) into the equation
y = 2x + b
4 = 2(2) + b
4 = 4 + b Subtract 4 on both sides
0 = b
y = 2x + 0
y = 2x
Answer: x = 7, x = -15
Step-by-step explanation:
This is an absolute value equation, so it has to be simplified first
|x+4|+10=21
|x+4|=11
Then you set it equal to the two values it can be, getting rid of the absolute value sign.
x+4=11
x+4=-11
x = 7
x = -15
Voila!
