Answer:
D
Step-by-step explanation:
1: B $3.85
2: C The rabbit; 14 miles per hour
3: C 2 1/2 miles
1. Reason: To find the price per gallon, all you need to do is divide 46.20 by 12 to get 3.85
2. Reason: To find which animal is faster all you have to do is subtract the greater number, which is the rabbit that travels 35 miles per hour from the smaller number which is the fox that travels 21 miles.
Subtract: 35-21= 14. So the rabbit is faster by 14 miles.
3. Reason: If Randy walks 1/2 mile in every 1/5 hour, to find the much he will walk in a hour you could count up:
1/2 mile = 1/5 hour
1 mile = 2/5 hour
1 1/2 mile = 3/5 hour
2 mile = 4/5 hour
2 1/2 mile = 1 hour
So, Randy will travel 2 1/2 miles in a hour.
Not sure for (b)
Step-by-step explanation:
(a)55+80+x=180 (angles inside the triangle)
135+×=+180
x=180-135
x=45
5/7 is greater than 4/6 or 2/3
2/3 is 66% or .6 repeated
5/7 is 71.4% or .714285 repeated
therefore 5/7 > 2/3
Answer:
x =
Step-by-step explanation:
Step 1: Write out formula
a(x - b) = a² + bx
Step 2: Distribute
ax - ab = a² + bx
Step 3: Add <em>ab</em> to both sides
ax = a² + bx + ab
Step 4: Subtract <em>bx</em> on both sides
ax - bx = a² + ab
Step 5: Factor
x(a - b) = a² + ab
Step 6: Divide (a - b) on both sides
x =
Step 7: Factor
x =
And we have our final answer!
