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:
x <= -5
Step-by-step explanation:
4x + 12 <= -8
4x <= -20
x <= -5
<h3>Answer:</h3>
none of these has "no solution"
<h3>Explanation:</h3>
A. The solution is (8/3, 3)
B. The second equation is -1/2 times the first, so these describe the same line. The system has an <em>infinite number of solutions</em>.
C. The solution is (-4, -2)
D. The solution is (4, -2)
E. The second equation is 2 times the first, so these describe the same line. The system has an <em>infinite number of solutions</em>.

A system of equations will have "no solution" when it describes parallel lines—lines that do not intersect. In standard form, such equations are recognizable by their different constants. For example,
- 3x -4y = -4
- 3x -4y = 20 . . . . . . 20 is different from -4
have different constants, so the equations describe parallel lines.
We could multiply one of these by -2 and the system would still be "inconsistent"—having no solution.
Answer:
A. T, U
Step-by-step explanation:
T and U are stretched across the paper. the others seem a bit close or smaller to the size of X and Y, but when you look at T and U they seem longer than X an Y
Hope this helps!!! :)
