Subtract the two equations to eliminate g :
(3g + h) - (3g - 2h) = (5 1/5) - (-6 4/5)
3h = (5 1/5) + (6 4/5)
Write the mixed numbers as improper fractions with a common denominator and solve for h :
3h = (25/5 + 1/5) + (30/5 + 4/5)
3h = 26/5 + 34/5
3h = 60/5
3h = 12
h = 12/3
h = 4
Solve for g :
3g + h = 5 1/5
3g + 4 = 5 1/5
3g + 4 = 26/5
3g = 26/5 - 4
3g = 26/5 - 20/5
3g = 6/5
g = (6/5)/3
g = 2/5
Answer:
62.4
Step-by-step explanation:
1/3*5.2*4.5*8=62.4
Your answer is 48 minutes because you divide 6.72 by 0.14
Answer:
11 1/12
Step-by-step explanation:
6 1/3 = 19/3
7 1/4 = 29/4
2 1/2 = 5/2
19/3 + 29/4 - 5/2
We must find the LCM of 3, 4, and 2. This happens to be 12
3*4 = 12
4*3 = 12
2*6 = 12
Multiply each fraction by the factor that'll get it to 12.
19/3 * 4/4 = 76/12
29/4 * 3/3 = 87/12
5/2 * 6/6 = 30/12
Now go through the problem
76/12 + 87/12 - 30/12
76 + 87 = 163
163/12 - 30/12
163 - 30 = 133
133/12
Simplify
133/12 = 11.0833... or 11 1/12
Hope this helps.
