5:15 = 30:x so 6x15 is 80
It will take him 80 minutes
Answer:
im bad but good luck on your math(:
Step-by-step explanation:
Assuming the number cube is a die numbered 1-6,
The probability of flipping a coin and getting heads and the probability of rolling a 3 on the die are independent of each other.
-There are two sides of a coin, heads and tails. You have two possible results from the coin - heads, or tails. You have a 1 in 2 probability of getting either.
-There are six sides of a die. There are six possible results from the die - 1, 2, 3, 4, 5, and 6. You have a 1 in 6 probability of getting any of the results.
The probability of both happening (<em>and</em>) can be determined by multiplying the two probabilities.
Hope this helps!

D=50h, because s/he can go 50 miles in one hour, and the distance depends on the number of hours driven for.
Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know:</h3>
- linear equation
- linear equation word problems
- PEMDAS
<h3>tips and formulas:</h3>
<h3>let's solve:</h3>
all we need to care about the middle condition which is
<h3>the new test score is 15 points more than the original score</h3>
given that
original score is x
New score is y
if you pay attention to the given condition
we can find it same as linear equation
therefore
according to the question
the equation is
<h2>y=x+15</h2>
