Answer:
the man is 52 years old
Step-by-step explanation:
man: 35+x
son:x
y=884/x
x(35+x)=884
35x+x^2=884
35x+x^2-884=884-884 . 884/-17+52=35
x^2+35x-884=0
(x-17)(x+52)=0
x=17 . x=-52 (age can't be negative)
man:35+17=52
Answer:
Let the fraction be qp
So q=p+7
q−6p+17=2
⇒p+7−6p+17=2
⇒p+1p+17=2
⇒p+17=2p+2
⇒p=15
q=15+7=22
So qp=2215.

The value of A is 4
<span>4x2 – 20x + 3 = 0
-3 -3
4x2 - 20 x = - 3
Pull out common factor which is 4
4 ( x2 - 5x) = - 3</span>
<span>m∠3 = 180 -(x + x - 6 )
= 180 - 2x + 6
= 186 - 2x</span>
Answer:
Either B or C but i'll have to say B if I had to choose.
