Answer:
x + 3 = 7/2
100x = 50
16/x = 24
Step-by-step explanation:
The value of x is 1/2 in the three equations.
The variable x is in the left side of the equations.

Answer:
$189.32
Step-by-step explanation:
Add all of the numbers shown to the beginning balance to find the ending balance.
$92.19 -39.35 +49.76 +87.35 +9.97 -10.60 = $189.32
Tristan's balance at the end of the month was $189.32.
__
There should be no confusion. Money deposited into the account increases the balance by the amount deposited.
Money spent from the account decreases the balance by the amount spent.
Here, amounts deposited are given a plus sign (+); amounts spent are given a minus sign (-).

<em>Additional comment</em>
It can be tedious to enter these numbers correctly into a calculator. Many folks prefer a calculator that provides a "tape", a record of the amounts and operations the calculator uses in the computation. Alternatively, you can put the numbers in a spreadsheet and use the SUM function to do the addition for you. That, too, makes it easy to check that numbers have been entered correctly.
The attachment shows the calculation done in a spreadsheet.
Answer:
a = 102.05
b = 393.76
B = 93°
Step-by-step explanation:
The law of sines tells you ...
a/sin(A) = b/sin(B) = c/sin(C)
Since the sum of angles in a triangle is 180°, angle B must be ...
B = 180° -72° -15° = 93°
and the unknown sides must be ...
a = c/sin(C)·sin(A) = 375·sin(15°)/sin(72°) ≈ 102.05192
B = 93°
b = 375·sin(93°)/sin(72°) ≈ 393.75796

The rounding requirement got cut out of your picture, so we can't help you with that.
Don’t Identify- 278.98
Female- 450.66
Male- 343.36
Considering these are people, you probably will need to round either up or down. If you round it would be:
Don’t Identify- 279
Female- 451
Male- 343
