Hey there!

$\bold{\frac{8(-14)}{(-8)-3(-13)}}$

$\bold{8\times-14=-112}$
$\bold{\frac{-112}{(-8)-3(-13)}}$
$\bold{3\times-13=39}$
$\bold{\frac{-112}{-8-39} }$
$\bold{-8-(-39)=31}$
$\boxed{\boxed{\bold{Answer:\frac{-112}{31}}}}$

Good luck on your assignment and enjoy your day!

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the dista

Yuki888 [10]

$d=v \cdot t$
d - distance
v - speed
t - time

Car A:
$v_1 \\
t_1=2 \\
d_1=v \cdot 2=2 v$

Car B:
15 mph faster than car A
$v_2=v_1+15 \\ t_2=1.5 \\ d_2= (v_1+15) \cdot 1.5=1.5v_1 + 22.5$

Both cars traveled equal distances:
$d_1=d_2 \\
2v_1 = 1.5v_1+22.5 \\
2v_1-1.5v_1=22.5 \\
0.5v_1=22.5 \\
v_1=45 \\ v_2=45 + 15 =60$

Car B traveled at the speed of 60 mph.
