Answer:
New length is 3 3/20 ft.
Step-by-step explanation:
The total board is 2 5/8 feet long. And since 5/6 of a foot is trimmed off, that means each piece of wood is 5/6 feet.
We can now set up an equation like this ---> 5/6 ⋅ x = 2 5/8
Now we're going to simplify ---> 5/6 ⋅ x = 2 5/8
5/6 ⋅ x = 21/8
(multiply both sides by 6)
5x = 63/4
(divide both sides by 5)
x = 63/20
x= 3.15
So, the new length is 3.15 feet long, or 3 3/20 in mixed fraction.
The degree is 4 because it is the largest exponent out of all the variables.
Answer:
10 carbs in snack bars
14 carbs in milk
Step-by-step explanation:
Glasses of Milk = m
Snack Bars = s
I am going to make this a system of equations:
2m + 3s = 58
4m + 2s = 76
I am going to simplify one of them for a s:
4m + 2s = 76
2s = 76 - 4m
s = 38 - 2m
I am going to insert this into the other equation:
2m + 3s = 58
2m + 3(38 - 2m) = 58
2m + 114 - 6m = 58
(-4)m + 114 = 58
(-4)m = -56
m = 14 calories
I am going to plug this m into one of the equations (doesn't matter which):
2(14) + 3s = 58
28 + 3s = 58
3s = 30
s = 10
You can plug these values back into each of the equations to make sure they work.
Hope it helps! UvU
Answer:
Step-by-step explanation:
I think you are just asking for the decimal answers.
3/20 = 0.15
9/50 = 0.18
38/200 = 0.19
Answer:
a.) Time = 6 hours
b.) Average Speed = 410 miles per hours
c.) Distance = 196 miles
Step-by-step explanation:
<h3><u>a.</u>)</h3>
A coach drives 360 miles at a speed of 60 mph.
So,
Time = Distance ÷ Speed
Time = 360 ÷ 60
Time = 6 hours
<h3>
<u>b.</u>)</h3>
A plan flies 1640 miles in 4 hours.
So,
Average Speed = Distance ÷ Time
Average Speed = 1640 ÷ 4
Average Speed = 410 miles per hours
<h3>
<u>c.</u>)</h3>
A bus drives 3½ hour at an average Speed of 56 mph.
So,
3½ hour = 3.5 hour
Distance = Average Speed × Time
Distance = 56 × 3.5
Distance = 196 miles
