Answer:
m + 180
———————
4
Step-by-step explanation:
1
Simplify —
4
Equation at the end of step 1 :
1
45 + (— • m)
4
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 4 as the denominator :
45 45 • 4
45 = —— = ——————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
45 • 4 + m m + 180
—————————— = ———————
4 4
Final result :
m + 180
———————
4
Exact form: 1/3
decimal form: 0.3333333.....
You are told that y=-5, so just use that value for y in the second equation...
5x+4(-5)=-20
5x-20=-20
5x=0
x=0 so the solution, when the lines intersect, is the point (0,-5)
We know that 1 lb = 16 oz
So lets convert the 20 lb to oz and then compare the two quantities in consistent units.
If 1 lb = 16 oz then 20 lb are equal to 20*16 oz, that is
20 lb = 20*16 oz = 320 oz
therefore,
320 oz are greater than 272 oz, or,
20 lb are greater that 272 oz
