Answer:
1.6
Step-by-step explanation:
Since y = 8
And x = 5,
You divide both values by the X Value
8 divided by 5 = 1.6
5 divided by 5 = 1
the ratio is 1:1.6
So the constant is 1.6
Answer:
Step-by-step explanation:
-Amy walks a distance of 7/8 mile
-Tom walks a distance of 4/8 mile.
#We immediately notice that Amy has walked a longer distance than Tom.
We subtract Tom's distance from Amy's to find how much further Amy walked;
Hence, Amy has walked 3/8 miles further than Tom has.
Set up the following equations:
x represents car A's speed, and y represents car B's speed.
We'll use elimination to solve this system of equations. Multiply the first equation by 7:
Combine both equations:
Divide both sides by 28 to get x by itself:
The speed of car A is
80 mph.Since we now know the value of one of the variables, we can plug it into the first equation:
Subtract 160 from both sides.
Divide both sides by 2 to get y by itself:
The speed of car B is
60 mph.
