Answer:
125/2 or 62.5 or 62 1/2 (x=)
Step-by-step explanation:
25/4=x/10 multiply everything by 20
25*20/4=20x/10 simplify
25*5=2x simplify
125=2x divide on both sides
125/2 or 62.5 or 62 1/2=x
Answer:
72.1 and -48.1
Step-by-step explanation:
I set up the equations x + y = 24 and x*y=-3468. Then I substituted for y and used the quadratic formula to come to two numbers rounded to about 72.1 and -48.1. Hope that helps :)
Answer:
y=2x+1
Step-by-step explanation:
Parallel = gradients are the same
Example: y=2/4x+5
Perpendicular = gradients are the inverse of each other
Example: y= -4/2x+1
Any equation would be correct unless the gradient is 2/4 or -4/2
First we need to establish the fact that angles on a straight line ALWYS add up to 180
So, we solve the equation for x which turns out to be 3
But,were not done. The question asks us to find the value of the angle BOC
so we substitute the value of x into the equation for BOC (which is 6x+29)
And then your answer is 47 degrees
