Answer:

x = 25

Step-by-step explanation:

According to the hint: The two angle measures would add up to 180°.

$(5x+10)+(2x-5)=180\\\\5x+10+2x-5=180\\\\5x+2x+10-5=180\\\\7x+5=180\\\\7x+5-5=180-5\\\\7x=175\\\\\frac{7x=175}{7}\\\\\boxed{x=25}$

Hope this helps.

A car traveling at a certain speed will travel 76 feet per second. How many miles will the car travel in 3.1 hours if it maintai

liubo4ka [24]

Keeping in mind that, there are 5280 feet in 1 mile, and 60 minutes in an hour and 60 seconds in each minute, thus 60*60 seconds in an hour, or 3600 seconds.

$\bf \cfrac{76~\underline{feet}}{\underline{sec}}\cdot \cfrac{mile}{5280~\underline{feet}}\cdot \cfrac{3600~\underline{sec}}{hr}\implies \cfrac{76\cdot 3600~mile}{5280~hr}
\\\\\\
\cfrac{570~mile}{11~hr}\approx 51.\overline{81}\frac{mile}{hr}\\\\

\textit{how many miles does it do in 3.1hrs?}\quad \cfrac{570}{11}\cdot 3.1$
