Answer:
7.5
Step-by-step explanation:
With base-ten blocks ,there would be the 3 units, 1 tens block , and five hundreds cubes
6x-1/5=3
add 1/5 to both sides
6x=1/5+3
convert 3 to fraction with 5 as denomenatory
3/1 times 5/5=15/5
6x=15/5+1/5
6x=16/5
divide both sides by 6
x=16/5 times 1/6
x=16/30
x=8/15
Answer:
This ratio is 0.6.
Step-by-step explanation:
This ratio is:
gold 37.5%
-------- = ----------- = -0.6
nickel 62.5%
In the slope intercept form equation of a line (y=ax+b) a represents the slope, and b represents the intercept, which is -5. Thus, we know y=ax-5. The slope can be found by creating a fraction with the change in y value on top, and the change of x value on the bottom. If we have two points (4, 1) and (0, -5) we can put this into a fraction -

, which simplifies down to -6/-4, or 3/2. Thus the answer is f(x)=
