Answer:
Step-by-step explanation:
Let the age of Seema be x and her father be 3x
After 12 years,
Age of Seema=x+12
Age of father=3x+12
Now we have,

Again,
Present age of her father=3x=3×12=36
Hence, the present age of Seema is 12 and her father is 36.
Answer:
slope = 
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 6y - 14x = 5 into this form
add 14x to both sides
6y = 14x + 5 ( divide all terms by 6 )
y =
x +
← in slope- intercept form
with slope m =
← in simplest form

Answer:
B
Step-by-step explanation:
Let the width be x, and the length be y
xy = 50
y = 2x
2x^2 = 50
x^2 = 25
x = 5
y = 10
3*8 = 24
9 i’m pretty sure bc if u do the square root of 87 and round it to the nearest whole number u get 9
