45 = 3(x + 1)
Answer:
x = 14
Step-by-step explanation:
Solving equation3(x + 1) = 45
3*x + 3*1 = 45 {Distributive property used: a*(b+c) =(a*b) +(a*c)}
3x + 3 = 45
Subtract 3 from both sides
3x = 45 - 3
3x = 42
Divide both sides by 3
x = 42/3

A is the principal amount after t number of years,
r is the rate at which the principal is been compounded, and P is the principal amount.
Given the principal amount of $570 is invested for a period of 10 years, and at a rate of 4% per year, therefore, the worth of the investment after 10 years will be,

The area of the rubber coating for a flat roof was 96 ft². The rectangular frame the carpenter built for the
flat roof has dimensions such that the length is 4 ft longer than the width. What are the dimensions?
Answer:
Length = 12 ft.
Width = 8 ft.
Step-by-step explanation:
Given :
Area = 96 ft²Length = Width + 4 ft.Let :
Length = (x + 4) ft.Width = x ft.Solving :
The formula for calculating area is : Area = Length x Width96 = (x + 4)(x)x² + 4x - 96 = 0x² + 12x - 8x - 96 = 0x(x + 12) - 8(x + 12) = 0(x - 8)(x + 12) = 0x - 8 = 0 ⇒ x = 8The dimensions are :

Answers:
bio = 258
sociology = 169
============================================================
Work Shown:
x = number of bio textbooks
y = number of sociology textbooks
x+y = 427 books sold total
y = x-89 since 89 less sociology textbooks were sold compared to bio
Apply substitution to get the following
x+y = 427
x+x-89 = 427 ... replace y with x-89
2x-89 = 427
2x = 427+89
2x = 516
x = 516/2
x = 258 bio textbooks were sold
y = x-89
y = 258-89
y = 169 sociology textbooks were sold

Step-by-step explanation:
How many seconds makes a year?
it is 31,536,000 seconds
for an approximate result, divide the time value by 3.154⁷
therefore 205000/3.154⁷

Using Desmos, enter the data from the table and create a linear regression equation. Let x = time in years since
1900 and let y = minimum hourly wage. Remember, the line that is graphed is a “line of best fit” or a “trend line.”
The equation for that line is called a linear regression equation. Use the information given to you by desmos to
write the linear regression equation. Do not round.
Use the equation to estimate the minimum hourly wage of a U.S. worker in 2025. Use Desmos and round to the
nearest cent.
Minimum hourly wage =
Answer:
$8.61 (nearest cent)
Step-by-step explanation:
The graphed data with the line of best fit (attached).
From the graphing calculator, the given line of regression is:
y = 0.125873x - 7.11916
To estimate the minimum hourly wage in 2025:
⇒ x = 2025 - 1900 = 125
Substitute x = 125 into the equation:
⇒ y = 0.125873(125) - 7.11916
⇒ y = 8.614965
Therefore, minimum hourly wage = $8.61 (nearest cent)

In order to find equation:
Find slope:

How to convert decimals to other decimals
Answer:
Step 1 − Divide the decimal number to be converted by the value of the new base.
Step 2 − Get the remainder from Step 1 as the rightmost digit (least significant digit) of new base number.
Step 3 − Divide the quotient of the previous divide by the new base.
Step 4 − Record the remainder from Step 3 as the next digit (to the left) of the new base number.
Step-by-step explanation:
Repeat Steps 3 and 4, getting remainders from right to left, until the quotient becomes zero in Step 3.
The last remainder thus obtained will be the Most Significant Digit (MSD) of the new base number.

Yes,1/2 of an answer is zero answer.
[I REALLY DON'T KNOW I NEED HELP PLEASE] Fill in the blank with the word dependent or independent. 1. The equation y = 6-x defines y as a function of x. The variable x is the variable, because you can choose any value for it. The variable, because it depends on variable y is called the x. Once you have chosen a value for x, the value of y is determined.
It is dependent. Without the function of the variable (X), we wouldn’t understand the value of Y.

made?
OA. 6
OB. 6

Answer:
It should be 210, but that option isn't on here
Step-by-step explanation:
63 cups / 0.3 cups per serving = 210 servings
Answer:
C. 213?
Step-by-step explanation:
Not sure as you might've just copied and pasted in correctly as I do see you copied the bit where it says "Emma portfolio" and both A and B are both 6, as the answer. But 63/0.3 would give you 210 servings. So I'm not sure where the 3 extra servings are coming from.
