20 minutes = 1/3 of an hour
1/3 = 0.333
1/3 x 45mph = 15, so she drove 15 miles at 45mph
18-15 = 3
3 miles/ 20 mph = 0.15 hours
0.333+0.15 = 0.483 hours total
0.483 x 60 = 28.98 so approximately 29 minutes total driving time
7:15 + 29 minutes is 7:44 am she arrived at work
I think the answer is 30x+330>50x
Step-by-step explanation:
for the option A it was slightly changed,
cause the $30 was deposited by <em><u>helen</u></em> not <em><u>Vince.</u></em>
<em><u>so </u></em><em><u>check </u></em><em><u>that </u></em><em><u>well</u></em>
Answer:
a) 7 + (-4) = 3
b) (-6) + (-3) = -9
c) 2 -(-6) = 8
d) (-8) - (-13) = 5
Step-by-step explanation:
a) 7 + (-4)
= 7 + (-4)
= 3
b) (-6) + (-3)
= -6 - 3
= -9
c) 2 - (-6)
= 2 + 6
= 8
d) (-8) - (-13)
= -8 + 13
= 5
Answer:
Step-by-step explanation:
A solution set is the set of values which satisfy a given inequality. It means, each and every value in the solution set will satisfy the inequality and no other value will satisfy the inequality.
Example:
Solve 2x + 3 ≤ 7, where x is a natural number.
Solution:
2x + 3 ≤ 7
Subtracting 3 from both the sides,
2x ≤ 4
Dividing both sides by 2,
x ≤ 2
Since x is a natural number,
Solution set = {1,2}.
The answer is 137 your welcome
