We have x = (2/5)y and x + y = 35;
then, (2/5)y + y = 35;
2y + 5y = 175;
7y = 175;
y = 27;
x = 35 - 27;
x = 8;

Answer:
plz mark brainliest..
Step-by-step explanation:
AC is the hypotenuse = 10
AB is side opposite to <C
<C = 30°, <B = 90°
by 30°-60°-90° theorem
side opposite to 30° is equal to half of hypotenuse
therefore,
AB = 1/2 × AC
AB = 1/2 × 10
AB = 5
therefore number 5 is answer
hope it will help you
Answer:
x=2.5&.5
Step-by-step explanation:
The quadratic formula is (-b+or-sqrt(b^2-4ac)/2a
12+or-sqrt((-12^2)-4(4)(5))
12+or-sqrt(144-80)
12+or-sqrt(64)
(12+8)/8 and (12-8)/8
x=2.5 and x=.5
