Answer:
Step-by-step explanation:
Answer:
The two numbers are
4
and
6
.
Explanation:
Let one number be represented as
x
and the other as
y
.
According to the problem:
x
=
2
3
y
and
x
+
y
=
10
From the second equation we get:
x
+
y
=
10
∴
y
=
10
−
x
(subtracting
x
from both sides)
Replacing the value of
y
in the first equation we get:
x
=
2
3
y
x
=
2
3
(
10
−
x
)
Multiplying both sides by
3
we get:
3
x
=
2
(
10
−
x
)
Opening the brackets and simplifying we get:
3
x
=
20
−
2
x
Add
2
x
to both sides.
5
x
=
20
Divide both sides by
5
.
x
=
4
Since from the second equation we have:
x
+
y
=
10
substituting
x
with
4
we get:
4
+
y
=
10
Subtract
4
from both sides.
y
=
6
SOLUTION:
= ( 7 / 8 )m + 9 / 10 - 2m - 3 / 5
= - ( 9 / 8 )m + 3 / 10

Answer:
3.08 hours
Step-by-step explanation:
We assume you're interested in the time in hours.
![175\text{ mi}\times\dfrac{12\text{ s}}{1000\text{ ft}}\times\dfrac{5280\text{ ft}}{1\text{ mi}}\times\dfrac{1\text{ h}}{3600\text{ s}}=\dfrac{175\times12\times5280}{1000\times3600}\text{ h}=\boxed{3.08\text{ h}}](https://tex.z-dn.net/?f=175%5Ctext%7B%20mi%7D%5Ctimes%5Cdfrac%7B12%5Ctext%7B%20s%7D%7D%7B1000%5Ctext%7B%20ft%7D%7D%5Ctimes%5Cdfrac%7B5280%5Ctext%7B%20ft%7D%7D%7B1%5Ctext%7B%20mi%7D%7D%5Ctimes%5Cdfrac%7B1%5Ctext%7B%20h%7D%7D%7B3600%5Ctext%7B%20s%7D%7D%3D%5Cdfrac%7B175%5Ctimes12%5Ctimes5280%7D%7B1000%5Ctimes3600%7D%5Ctext%7B%20h%7D%3D%5Cboxed%7B3.08%5Ctext%7B%20h%7D%7D)
It will take 3.08 hours to travel 175 miles at that speed.
