Divide 2999 by 55 they YOU can round it to the nearest cent
You would need 6 packages for 27 students because 27 isn't divisible by 5 without a remainder and all students need pencils. So, you would need to bu another package of pencils.

Step-by-step explanation:
<u>Step 1: Define</u>
m(x) = 4x - 10
m(x) = -2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: -2 = 4x - 10
- Isolate <em>x</em> term: 8 = 4x
- Isolate <em>x</em>: 2 = x
- Rewrite: x = 2
Answer:
38°
Step-by-step explanation:
The measure of required angle can be obtained by using cosine law.
From the given triangle we find that:
a = 5, b = 3, c = 7,
Since,
cos (A) = (b^2 +c^2 - a^2) /2bc
Therefore,
cos (A) = (3^2 + 7^2 - 5^2) /(2*3*7)
cos (A) = (9 + 49 - 25) /(42)
cos (A) = (33) /(42)
cos (A) = 0.785714286
A = arccos(0.785714286)
A = 38.213210675°
A = 38°
