Answer:
400
Step-by-step explanation:
u = 50 km/hr
v = 100 km/hr
d = 300 km
b = 200 km/hr
= b*d/(u+v)
= 200* 300/(50+100)
= 400

Answer:
there is no solution
Step-by-step explanation:
y + 7 = 3x
6x - 2y = 6 which can be simplied to be 3x - y = 6 (divide by 2)
let y = 3x - 7
substitute: 3x -(3x - 7) = 6
3x - 3x + 7 = 6
7 ≠ 6 therefore, no solution
Step-by-step explanation:
Here, the second order of polynomial ax² + bx + c is factorized and expressed as the product of two linear factors. First, we have to find the two numbers that adds to 12 and if we multiply those numbers , we get 36 ( The two numbers should be 6 and 6 ).
