Assuming the credit card is for Kohl's,
You make a 45 dollar payment: your debt goes down by 45
You make a 97 dollar purchase: your debt goes up by 97
135-45+97
Your current debt is 187 dollars. Not a nice way to live if you ask me!

Explain exponential equations. DO NOT COPY + PASTE!! I will check
Answer:
Step-by-step explanation:
exponential equation has the same base on each side, the exponents must be equal. This also applies when the exponents are algebraic expressions. Therefore, we can solve many exponential equations by using the rules of exponents to rewrite each side as a power with the same base. Then we use the fact that exponential functions are one-to-one to set the exponents equal to one another and solve for the unknown.

hi someone pls help me with #2
Answer:
B
Step-by-step explanation:
Use the distributive property to simplify the following expression-(8+b)
Do you see the negative sign in front of the parentheses? That is -1.
Multiply each term inside the parentheses by -1.
Doing so, we get -8 -b.
Trisha uses 3 cups of sugar for every 2 teaspoons of baking soda to make a batch of cookies. Which equation should she use to find the number of teaspoons of baking soda, x, needed if she uses 9 cups of sugar?
Given:
Trisha uses 3 cups of sugar for every 2 teaspoons of baking soda to make a batch of cookies.
To find:
The equation that she should use to find the number of teaspoons of baking soda, x, needed if she uses 9 cups of sugar.
Solution:
Let the number of teaspoons of baking soda be x, that is needed if she uses 9 cups of sugar.
For every 2 teaspoons of baking soda Trisha uses 3 cups of sugar.
For every 1 teaspoons of baking soda Trisha uses [tex]\dfrac{3}{2}[/tex] cups of sugar.
For every x teaspoons of baking soda Trisha uses [tex]\dfrac{3}{2}x[/tex] cups of sugar.
Since she uses 9 cups of sugar for every x teaspoons of baking soda, therefore,
[tex]\dfrac{3}{2}x=9[/tex]
Multiply both sides by 2.
[tex]3x=18[/tex]
Divide both sides by 3.
[tex]x=6[/tex]
Therefore, the required equation is [tex]\dfrac{3}{2}x=9[/tex] and the number of required teaspoons of baking soda is 6.
is it proportional or non proportional
Answer:
proportional
Step-by-step explanation:
13/2=6.5
19.5/3=6.5
26/4=6.5
32.5/5=6.5
so if all equal the same they are proportional
5=45 ÷
What is the answer
45 ÷ 5 = 9
So, 5 = 45 ÷ 9

You hang two strings of decorative lights. Strand 1: changes between red and blue every 15 seconds. Strand 2: changes between green and gold every 18 seconds. Both strands just changed color. After how many seconds will the strands change color at the same time again?
Answer:
The strands change color at the same time again after 90 seconds
Step-by-step explanation:
We are told:
Strand 1: changes between red and blue every 15 seconds.
Strand 2: changes between green and gold every 18 seconds.
To solve for this question, we use the LCM method.
Step 1
List multiples of each number until the first common multiple is found.
Multiples of 15:
15, 30, 45, 60, 75, 90, 105, 120
Multiples of 18:
18, 36, 54, 72, 90, 108, 126
Therefore,
LCM(15, 18) = 90
The first common multiple is 90, and this is the lowest common multiple.
Therefore, the strands will change color at the same time again after 90 seconds.

The first and thirteenth terms of an arithmetic sequence are 7/9 and 4/5, respectively. What is the seventh term?
Here,
Let the first term be denoted by a and commom difference by b.
Now,
T1 = a
= 7/9
T13 = a + 12 d
or, 4/5 = 7/9 + 12d
or 12d = 4/5 -7/9
or, 12d = 1/45
or, d = 1/410.
then,
T7= a + 6d
= 7/9 + 1/410
= 2879/2870
Please check the answer and tell me whether it is correct or not.
i need help with this
Answer:
answer is A
Step-by-step explanation:
This symbol is called a tilde. In symbolic logic (a field of math
used a lot in computer sciences) it is used to denote "not." For
example, ~A means "not A." In some other contexts, it means
"approximately." For example, pi ~= 3.1416. (Note that sometimes it is
written above the equal sign, and sometimes it is used without an
equal sign - it depends on the situation and the publisher.)

A ball thrown straight up in the air travels 90 inches in the first tenth of a second. In the next tenth of a second the ball travels 85 inches. After each additional tenth of a second, the ball travels 5 inches less than it did during the preceding tenth of a second. How long will it take before the ball starts coming back down? What is the total distance that the ball has traveled once it reaches its maximum height?
Answer:
855
Step-by-step explanation:
1.9 seconds is 19 tenths, so that means we add using the information given, which is that the ball travels 5 fewer inches every tenth of a second:
Time | Inches traveled
0.1 | 90
0.2 | 85
0.3 | 80
0.4 | 75
0.5 | 70
0.6 | 65
0.7 | 60
0.8 | 55
0.9 | 50
1.0 | 45
1.1 | 40
1.2 | 35
1.3 | 30
1.4 | 25
1.5 | 20
1.6 | 15
1.7 | 10
1.8 | 5
1.9 | 0
90+85+80+75+70+65+60+55+50+45+40+35+30+25+20+15+10+5+0=855

There are 2 overlapping triangles here. If the vertical lines are parallel, then these triangles are similar, and corresponding sides occur in a fixed ratio. In particular, we have
2/3 = (2 + x) / (3 + (x + 7))
Solve for x :
2/3 = (2 + x) / (10 + x)
2 (10 + x) = 3 (2 + x)
20 + 2x = 6 + 3x
14 = x
