Answer:
Marissa did not change the direction of the inequality sign.
Step-by-step explanation:
Hello!
We can solve the inequality as well, and compare our steps to Marissa's to verify her steps.
Solve the inequality:[tex]-\frac x{12} > 7.8[/tex][tex](-12)\frac{x}{-12} > 7.8( -12)[/tex][tex]x < -93.6[/tex]We have the same number, but a different inequality sign. This is because we have to flip the inequality sign when multiplying and dividing by a negative number.
Therefore, the answer is the last option, Marissa has to flip the inequality sign when multiplying by a negative number.

All properties that were used to simplify the following problem:
1. commutative property of multiplication
2. multiplicative inverse 3. multiplicative identity
What is commutative property of addition?
The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.
The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.
For two numbers x and y, we have: x + y = y + x
Thus, if we take 3 numbers as a,b and c;
a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a
We have been given an expression;
2/7 • 53 • 7/2
53 • 2/7 • 7/2
53 • 1
53
Then all properties that were used to simplify the following problem:
1. commutative property of multiplication
2. multiplicative inverse
3. multiplicative identity

On monday, your bank account balance was -$12.58. Because you didn't realize this, you wrote a check for $30.72 for groceries. a) What is the new balance in your checking account? b) The bank charges a $25 fee for playing a check on a negative balance. What is the balance in your checking account after this fee? c) How much money do you need to deposit to bring your account balance back up to $0 after the fee?
Answer:
a) The new balance in your checking account is -$12.58 - $30.72 = -$43.30.
b) After the bank charges a $25 fee for overdrafting, the balance in your checking account will be -$43.30 - $25 = -$68.30.
c) To bring your account balance back up to $0 after the fee, you will need to deposit $68.30.
Step-by-step explanation:
Answer:
First, you subtract the 30.72 from the -12.58 which is -43.03 which is therefore how much you have in your account. Then we subtract another 25 for the fee. -68.03 Is how much you have after paying the fee.
Therefore, to get to 0, you need to pay 68 dollars and 3 cents.

Ava bought snacks for her team's practice. She bought a bag of oranges for $2.71 and a 4-pack of juice bottles. The total cost before tax was $6.75. Write and solve an equation which can be used to determine jj, how much each bottle of juice cost.
Answer: Let j be the cost of each juice bottle.
The total cost of the juice bottles is 4j. The total cost of the oranges and juice bottles is $6.75.
Thus, the equation that represents the given information is: 4j + $2.71 = $6.75. Subtract $2.71 from both sides to get: 4j = $4.04. Divide both sides by 4 to get: j = $1.01.
Therefore, each juice bottle costs $1.01.
Step-by-step explanation:
Total cost = cost of a bag of oranges + cost of 4-pack juice bottles
$6.75= $2.71 + (4 x jj)
$6.75 = $2.71 + 4jj
take similar terms: $6.75 - $2.71 = 4jj
Add similar terms: $4.04 = 4jj
Divide both sides of the equation by 4: jj = $4.04 / 4=
jj = $1.01

$11.69
$75.50
$93.62
$105.50
Answer:
Step-by-step explanation:
Your friend just returned to the United States from their trip to Nepal and wants to exchange their 8,153 Nepalese rupees for U.S. dollars. How many dollars will they receive if the current exchange rate is 1 U.S. dollar to 124 Nepalese rupees?
our friend will get $ 65.75 in exchange for 8153 Nepali Rupees.
Currency Exchange rate:
The price of the native currency relative to another currency is referred to as the foreign exchange rate. Comparing different currencies to demonstrate their relative values is the goal of international exchange.
The rate at which one currency is exchanged for another or the price of one currency expressed in terms of another currency is two additional definitions of the foreign exchange rate.
Here given that
Your friend is just returned from Nepal to the United States
And wants to exchange 8,153 Nepalese rupees for U.S. dollars
The current exchange rate is 1 U.S dollar = 124 Nepalese Rupee
Let us assume that your friend will get x dollars in exchange
As give that 1 dollar = 124 Nepalese Rupees
Then x dollars = x × 124 Nepalese Rupees

Describe the pros and the cons of using the standard form of a line to graph an equation.
Answer:
The standard form of a line is expressed as Ax + By = C, where A, B, and C are constants and x and y represent the variables. One advantage of using the standard form to graph a line is that it is relatively easy to determine the slope and y-intercept of the line from the constants A and B. This can be particularly useful when trying to analyze the behavior of the line.
Another advantage of using the standard form is that it allows you to easily determine the equation of the line when given a set of points. For example, if you are given the points (2,4) and (3,6), you can use the standard form to find the equation of the line that passes through these points by substituting the coordinates into the form and solving for the constants.
One potential disadvantage of using the standard form is that it can be more difficult to interpret the meaning of the constants A, B, and C in terms of the context of the problem. For example, if the line represents the cost of a product, it may be more intuitive to express the equation in terms of the variables x (the number of units) and y (the cost). In this case, it may be more useful to use the slope-intercept form of the equation, which is expressed as y = mx + b, where m is the slope and b is the y-intercept.
