Answer:
40 miles
Step-by-step explanation:
Let's set <em>x</em> to the number of miles driven, and <em>t</em> to the number of hours it took to drive.
We know that 40<em>t</em> is equal to <em>x</em>.
We also know that 40<em>t</em> is equal to 30(<em>t</em> + 1/3).
Solve for t:
40t = 30(t+1/3)
40t = 30t + 10
Subtract 30t from both sides:
10t = 10
Divide 10 from both sides:
t = 1
40t = 40 x 1 = 40 miles
<span>If you want to convert 15.1 into a fraction, you can do it like this:
15 <span>equals to 15</span>/1 <span>and </span>0.1 <span>equals to 1</span>/10
<span>The result is 15</span> 1/10.
If you want to make it a pure fraction, you have
to make one additional step:
<span>because you want to add 15/1 and 1/10, you
have to get the same denominators, so 15/1 changes to 150</span>/10.
<span>Now, you can add </span>150/10 and 1/10<span>.
The result is </span>151/10<span>.

The number half way between 13 and 37 is 25
Y=90° by inspection
w=180-(50+y)=160-(50+90)=40°
x=180-(w+x)=180-(40+97)=43°
z=180-(x+90)=180-(43+90)=47°
