-2n + 9mn - 17np
All you do is simplify the equation by distributing and multiplying the 1/3n to each of the numbers.
Hope this helps!
Answer:
a=(c+2b)/5
Step-by-step explanation:
Like terms in one side to subject a.
When exchanging sides make sure u do inverse operations. Therefore;
9a - 4a = c + 2b
5a = c + 2b
a = (c+2b)/5
Answer:
300 km
Step-by-step explanation:
3 hours and 45 minutes = 3
Speed = 80 km per hour.
80 × 3 = 240 km
80 ×
= 60
240 + 60 = 300
All you have to do is multiply the top and bottom by the same number (I'll do two). 5 times 2 = 10, and 8 times 2 = 16. 10/16 is equivalent to 5/8. A proportion for this can be written as 5/8 = 10/16.
Answer:
(x+100) = 120 & 6x= 120
Step-by-step explanation:
Vertical angles Rule:
(x+100)=6x
100=5x
20=x
Knowing what x is, just plug it back in to the original problems and solve!
