Write a situation for 15x - 20 ≤ 130 and solve
To write a situation for the inequality 15x - 20 ≤ 130 and solve it, let's assume that x represents the number of hours a student can study. The solution to the inequality is x ≤ 10, meaning the student needs to study for 10 hours or less to complete the required amount of work.
Explanation:To write a situation for the inequality 15x - 20 ≤ 130, let's assume that x represents the number of hours a student can study. In this situation, the left-hand side of the inequality represents the amount of work the student has already completed (15x - 20) and the right-hand side represents the total amount of work the student needs to complete (130). The inequality states that the amount of work completed should be less than or equal to the total amount of work required. To solve the inequality, we can follow these steps:
Add 20 to both sides of the inequality: 15x - 20 + 20 ≤ 130 + 20, which simplifies to 15x ≤ 150.Divide both sides by 15 to isolate the variable x: 15x/15 ≤ 150/15, which simplifies to x ≤ 10.Therefore, the solution to the inequality is x ≤ 10. This means that the student needs to study for 10 hours or less in order to complete the required amount of work.

How does place value help me subtract decimals
Place value helps you subtract decimals by aligning the decimal points and subtracting digit by digit.
Explanation:Place value helps you subtract decimals by aligning the decimal points and subtracting digit by digit. Start from the right and subtract the digits in the ones place, then move to the tenths place, hundredths place, and so on. If the top number is smaller than the bottom number in a place value column, you may need to borrow from the place value to the left.

7 berries are 5 less than twice the number of berries Mickey had for lunch.
The subject of this question is Mathematics.
Explanation:To define the subject of the question, we can see that it involves a mathematical problem. The question asks about the relationship between the number of berries a student has and the number of berries Mickey had for lunch. Therefore, the subject of this question is Mathematics.
7 berries are 5 less than twice the number of berries Mickey had for lunch can be represented as 7 = 2m - 5. Therefore, the correct option is c.
The problem states: "7 berries are 5 less than twice the number of berries Mickey had for lunch."
Let's represent the number of berries Mickey had for lunch as 'm'.
Now, translate the problem into an equation based on the information given:
"7 berries are 5 less than twice the number of berries Mickey had for lunch."
Twice the number of berries Mickey had for lunch is 2 times 'm', which is 2m.
"5 less than twice the number of berries Mickey had for lunch" means subtracting 5 from twice the number, so it's 2m - 5.
And finally, the equation becomes:
7 = 2m - 5
So, the correct representation of the situation in an equation is option C: [tex]$7 = 2m - 5$[/tex].
The complete question is given below:
7 berries are 5 less than twice the number of berries Mickey had for lunch. Choose the correct linear equation.
A. [tex]$7=5-2 m$[/tex]
C. [tex]$7=2 m-5$[/tex]
B. [tex]$5=2 m-7$[/tex]
D. [tex]$12=\frac{m}{2}$[/tex]

3. Susan invested $10,000 in an account that earned 3% interest, compounded monthly.
a. Write an exponential growth/decay formula to model the situation.
b. What is the value of this account after 5 years? Express your answer rounded to the nearest cent.
A) total = 10,000 *(1+0.03/12)^(12*t)
B) t = 5 years
10,000 *(1+0.03/12)^(12*5 ) = $11,616.17
The value of Susan's account after 5 years, compounding monthly with a 3% interest rate, is approximately $11,593.74.
To model the situation, we can use the formula for Compound Interest: A = P(1+r/n)^(nt), where A is the amount after time t, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per time period, and t is the time in years.
In this case, P = $10,000, r = 3% or 0.03, n = 12 (compounded monthly), and t = 5.
Substituting these values into the formula, we get:
A = $10,000(1+0.03/12)^(12*5)
Calculating this expression gives us an amount of approximately $11,593.74 after 5 years.
Rounded to the nearest cent, the value of the account is $11,593.74.

Amy is in a craft store looking at packages of Pom-poms. Amy sees packages of four red pom-poms. Amy says she can buy seven packages of four pom-poms or four packages of seven pom-poms because she will get the same total of pom-poms. Is Amy correct? Show all mathematical thinking.
Amy is incorrect because both options will give her the same total number of pom-poms.
Explanation:Amy is incorrect in her statement. Let's calculate the total number of pom-poms in each scenario. If she buys 7 packages of 4 pom-poms, she would have 7 * 4 = 28 pom-poms. On the other hand, if she buys 4 packages of 7 pom-poms, she would have 4 * 7 = 28 pom-poms as well. So, both options result in the same total number of pom-poms.
Consider the two functions which statement is true
The slope of the line in the graph is 1/2, and for the table the slope is 2.
Which is true about the two functions?We can se two linear functions, remember that if a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope of the line is given by the formula:
a = (y₂ - y₁)/(x₂ - x₁)
For the first line we can see it passes through (-4, 0) and (0, 2), then the slope is.
a = (2 - 0)/(0 + 4) = 1/2
For line b we can use the first two pairs in the table (2, 3) and (3, 5)
So the slope is:
a = (5 - 3)/(3 - 2) = 2
These are the slopes of the lines.

the original cost of a lamp is $18.95 . The lamp is on sale for 75% off . How much will you pay ?
Answer:
$4.74
Step-by-step explanation:
We have been given that the original cost of a lamp is $18.95 . The lamp is on sale for 75% off.
The cost of lamp after sale would be 25% (100-75) of $18.95.
[tex]\text{The cost of lamp after sale}=\$18.95\times \frac{25}{100}[/tex]
[tex]\text{The cost of lamp after sale}=\$18.95\times 0.25[/tex]
[tex]\text{The cost of lamp after sale}=\$4.7375[/tex]
[tex]\text{The cost of lamp after sale}\approx \$4.74[/tex]
Therefore, you will have to pay $4.74 for the lamp.
