Answer:
around like 33.50$
Step-by-step explanation:
All you have to do is take the number of hours times the amount of money per hour ( so like the equation would look like y=5x) and since the 45 minutes isn't a full hour it shouldn't matter. Just in case though we'll consider the 45 minutes and make it a .7 and multiply that by 5 as well and we get 3.5. Now we just take 5*6+3.5 and bang.
A) f(x) = 2x - 3
f(0) = 2(0) - 3
f(0) = 0 - 3
f(0) = -3
b) f(x) = 2x - 3
f(-2) = 2(-2) - 3
f(-2) = -4 - 3
f(-2) = -7
c) f(x) = 2x - 3
f(3) = 2(3) - 3
f(3) = 6 - 3
f(3) = 3
d) f(x) = 2x - 3
f(-1) = 2(-1) - 3
f(-1) = -2 - 3
f(-1) = -5
Answer:
Create equivalent expressions in the equation that all have equal bases, then solve for
x
.
Exact Form:
5/3
Decimal Form:
x
=
1.6
Mixed Number Form:
x
=
1 2/3
His speed was 1.5 mph
Explanation: It took him 20 minutes (1/3 of an hour) to hike 1/2 mile. 20 times 3 is 1 hour so 1/2 mile times 3 is 1.5 miles in one hour.
