Answer:
3 hours
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s ----> the speed in mph
d -----> the distance in miles
t ----> the time in hours
x ----> distance traveled by Daisy to the meeting point
60-x ----> distance traveled by Sally to the meeting point
so
Solve for d
<em>Distance traveled by Daisy to the meeting point</em>
we have
substitute
----> equation A
<em>Distance traveled by Sally to the meeting point</em>
we have
substitute
----> equation B
substitute equation A in equation B
solve for t
Answer:
a. x=7 b. x= 4.5 c. c= 3
Step-by-step explanation:
a. 5x=35
5x/5=35/5
x = 7
b. 4x=18
4x/4=18/4
x=4.5
c. 6c-2c=12
4c = 12
4c/4 = 12/4
c=3
Answer:
hey there hope this answer helps you out
Step-by-step explanation:
we have two functions f(x) and g(x) such that
and
solving for f ° g, we'll substitute the x in f(x) by the value of g(x)
taking x common in denominator
for a function to exist it should not have 0 in its denominator
checking the values of x for which the denominator of f ° g becomes 0 :-
so the function doesn't exist at values x = 0, -6
<h3>So, <u>0, -6</u> cannot be in the domain of f°g</h3>

explanation:
0.25x+7=45.50
subtract 7 from both sides
0.25x=38.5
divide both sides by 0.25
x=154
