Speeds are s_c for car, s_m for motorcycle.
time is 2
distance of car is:
d_c = d_m + 20, d_m is distance of motorcycle.
speed is defined as:
s = d/t, distance over time.
hence:
d_c/2 = s_c = d_m/2 + 10
s_c = s_m + 10
from problem statement we know:
s_c = 2s_m - 30
so we have 2 simultaneous equations:
<span>s_c = s_m + 10
</span><span>s_c = 2s_m - 30
</span>
multiply second by -1 and sum them both:
<span> s_c = s_m + 10
</span>-s_c = -2s_m + 30
-------------------------
0 = -s_m + 40
s_m = 40
that is the speed of the motorcycle
s_c = <span>s_m + 10
</span> s_c = 40<span> + 10
</span>s_c = 50
that is the speed of car, both speeds in miles per hour
Answer:4.68, 234, 228, 76
Step-by-step explanation: if you do what the problem is telling then you end up with 4.68 for the decimal 234 seasonings the list of ing multiplied by 3 = 228 the milk and cheese is 6/1 or 6 their yo go
Ur close but it is 0.023 you were off just a bit
To find the domain of a function you have to find all the possible input values.
