Answer:
the equation 20+5r=50 should help you see how many rides he can ride.
Step-by-step explanation:
20+5r=50
1. <em>Subtract 20 from both sides. </em>
5r=30
2. <em>Divide by 5 to isolate r.</em>
r=6
Sam can ride 6 rides.
Answer:
The shorter piece x = 8.4 in
The longer one y = 15.6 in
Step-by-step explanation:
If we cut a string length L in to unequal pieces we get two pieces
first one with length x and the other one with length y
Let call x the smaller piece, then y = L - x will be the longer one
If x = 35 % then
x = 0,35* L and
y = L - x = L - 0,35*L ⇒ y = 0,65 L ⇒ y = 0.65*24
Now if L = 24 in
x = 0,35*24 ⇒ x = 8.4 in
and
L - x = 0.65*L ⇒ L - x = 0.65*24 y = L - x = 15.6 in
as way of verification you can add the length of the two pieces and find:
8.4 + 15.6 = 24 in
Answer:
f(10) = 342
Step-by-step explanation:
f(x) = 3x² + 6x - 18
f(10 = 3(10)² + 6(10) - 18
f(10) = 3(100) + 60 - 18
f(10) = 300 + 60 - 18
f(10) = 360 - 18
f(10) = 342
20/t=v and 12/t=(v-4) solve both for t
t=20/v and t=12/(v-4) since t=t
20/v=12/(v-4) cross multiplying...
20v-80=12v
8v-80=0
8v=80
v=10mph
The outbound speed was 10mph
