Solve for one variable x or y first. So lets solve for x. If you take the first equation x= -12 -5y. You then plug that into the second equation
5(-12-5y) +4y = 24
now you solve for y
-60 - 25y + 4y =24
-21y=84
y=-4
Now you plug in y back into either equation and you get x=8
Well there can be two different solutions for this but i will choose the easier one. Obviously one requires a system of equations which obviously will involve a lot of thinking and some good algebra solving in order for them to solve.
As for hit and trial it is very easy, we can just keep adding the distance as we know they are in different directions. 9 + 6 = 15. So 15 x 2 = 30 miles. So after around 2 hours they will be 30 miles apart if they continue at the same pace.
Answer: full budget of 100% will be 1600
Step-by-step explanation:
If 75% = 1200
Full budget will be 100%
Represent the question as if 75% = 1200
Then 100% = x
Cross multiply:
75%x = 1200%
Divide both sides by 75%
x = 1200%/75%
x = 16 × 100
= 1600
Answer: 2 & 13
Hope this helps you out! ☺
In your questions where the segment and circles create many relationship addressed in the theorem throughout this unit. So the following are the answers:
