Step-by-step explanation:
0.5 miles/ 10 minutes* (60 minutes/ 1 hour)= 3 miles/hour.
0.25 miles/ 6 minutes* (60 minutes/ 1 hour)= 2.5 miles/hour.
The unit rate of Ron is 3 miles/hour.
The unit rate of Steve is 2.5 miles/hour.
Therefore, Ron walks faster~
Answer:
Whether her conversion is correct or not, you can just base it on the true answer. For this problem, we apply the technique of dimensional analysis. You can like units if they both appear on the numerator and the denominator side. The solution is as follows:
Mass in ounces = 3 kg * (1,000 g/ 1 kg) * (1 ounce/28.35 g) = 105.82 ounces
Answer:
25/8
Step-by-step explanation:
Given That:
R = 8x+4y
X= 8
R = 30.
So, 8 x 8 +4y = 30
Simplify, Rearrange and solve.
64 + 4y = 30
4y = 30/64 = 15/32
y = 15/32 divided by 4
y = 15 / 32 x 1/4
y = 15/(32 x 4) = 15/128
hope this helps
Answer: 7a
Step-by-step explanation: Since they are like terms, you can just add or subtract them.
4a - 5a = -1a
2a + 6a = 8a
-1a + 8a = 7a
