Answer: 1:15pm
Step-by-step explanation:
11
If you replace the x with 11, the new equation would be 10+5(11)=65. First, multiply 5 and 11, your answer would be 55, then add the ten, you would get 65. Which makes the equation true, because 65=65.
I hope this helps

Answer:
tan A = -15/8.
Step-by-step explanation:
sin^2a = 1 - cos^2A
= 1 - (-8/17)^2
= 225/289
So sin A= 15/17
tan A = sin A / cos A
= 15/17 / -8/17
= 15/-8
= -15/8.

Answer:
The required expression is s = m + n
Step-by-step explanation:
Let m be the number of index cards stuffed in the envelopes and n be the number of extra index cards.
Let s be the total number of index cards.
Then, s = m + n represents the number of index cards the boys started with.
For Marty,
He has 15 stuffed envelopes and 4 extra index cards.
So, m = 15, n = 4
Therefore, s = 15 + 4 = 19
Marty started with 19 cards.
For Stewart,
He has 12 stuffed envelopes and 6 extra index cards.
So, m = 12, n = 6
Therefore, s = 12 + 6 = 18
Steward started with 18 cards.
