3 is less than 9 there fore 3.69 os smaller than 9.63
They are all alike because they are all angles
8/12 is left
3/4 is equivalent to 9/12 (multiply by 3)
9/12 minus 1/12 is 8/12
Answer:
Brainliest please
50years is their ages now
Step-by-step explanation:
<h3>use algebra</h3>
onyango= 3a
daughter= let it be a
son= he is 4 times less than his father, 3/4a
8years
8+3a+a+8+3/4a+a
a+8+3/4a+a
7/4+1 = 8/4a+8 + 12y 20= 8/4a = 40years is the father 8 years later, so his present age is 40-8
32y= father now
daughter= 1/3×32=10years
son= 1/4×32= 8yrs
add 32+10+8= 50years
A. x=3/2
D. x=1/2
Solve for x over the real numbers:
4 x^2 - 8 x + 3 = 0
The left hand side factors into a product with two terms:
(2 x - 3) (2 x - 1) = 0
Split into two equations:
2 x - 3 = 0 or 2 x - 1 = 0
Add 3 to both sides:
2 x = 3 or 2 x - 1 = 0
Divide both sides by 2:
x = 3/2 or 2 x - 1 = 0
Add 1 to both sides:
x = 3/2 or 2 x = 1
Divide both sides by 2:
Answer: x = 3/2 or x = 1/2
