Answer is 3. You have to do what’s in the parentheses first: 10+2-8=4. Then multiply 4 • 2 = 8 and then finally subtract: 8-5=3
68 minus 19 is 49
So the answer is there are 49 more children in the school then on the playground.
Answer:
2k³ is the GCF.
Step-by-step explanation:
GCF of 
Finding the factors:
=10k³[Factoring 10k³]
=2×5×k×k×k
=6k³[Factoring 6k³]
=2×3×k×k×k
Common factors in 10k³ and 6k³.
=2×k³
=2k³
The distance, s = 40t₁ where t₁ is the time to complete the outward journey.
The same distance = vt₂ where t₂ is the time to complete the return journey at speed v.
For the whole journey, 2s=60(t₁+t₂). Therefore s=30(t₁+t₂)=40t₁=vt₂.
30t₁+30t₂=40t₁, 10t₁=30t₂, t₁=3t₂, so s=120t₂=vt₂ and v=120kph.
The rule to convert a mixed fraction to an improper fraction is

Here in 
Here a = 422, b = 8 and c = 100
Now a × c = 422 × 100 = 42200
And 42200 + 8 = 42208
So we have

This fraction can also be reduced as

Hence
