30 batches/6 batches = 5 eggs per batch
6r+7=13+7r
Move 7r to the other side. Sign changes from +7r to -7r.
6r-7r+7=13+7r-7r
6r-7r+7=13
-r+7=13
Move +r to the other side. Sign changes from +7 to -7.
-r+7-7=13-7
-r=6
Multiply by -1 to get positive and for 6
-r(-1)=6(-1)
r=-6
Answer: r=-6
Answer:
1.6 hours
Step-by-step explanation:
Their separation speed is 95 +105 = 200 miles per hour. The time required for the given distance is ...
time = distance/speed
time = (320 mi)/(200 mi/h) = 1.6 h
It will take 1.6 hours for the trains to be 320 miles apart.
Rewrite using the formula for the standard form.
3xy^3 + 9x^2y - 2y^2 - 4x
