4. Solve the following inequality: 3y-1 less than 3
3y - 1 < 3
Isolate the y. Treat the less than or equal like an equal sign.
Do the opposite of PEMDAS. First, add 1 to both sides
3y - 1 (+1) < 3 (+1)
3y < 4
Next, divide 3 from both sides
3y/3 < 4/3
y < 4/3
y < 4/3 is your answer

A pizza eating participant can eat 3 slices ok pizza in 2 minutes if he continues at this rate then how many slices of pizza will he eat in 10 minutes
at this rate, he can eat 15 slices of pizza in 10 minutes **wow!!**
we can do this by setting it up as a proportion: 3slices/ 2 minutes= ?/1 minute
we divide 3 by 2 to get how many slices he can eat in one minute, which is 1.5
so, now, we just have to multiply 1.5 times 10 minutes, and we get 15 slices of pizza per 10 minutes

Mark and his friends Byron were watching a superhero movies. During the movie mark ate 5 pieces of candy . Byron ate 7 times as much candy as mark. How much candy did Byron eat.?
Final answer:
To find out how much candy Byron ate, we multiply the number of candies Mark ate, which is 5, by 7. Byron ate a total of 35 pieces of candy.
Explanation:
The question involves solving a basic multiplication problem to determine how much candy Byron ate if Mark ate 5 pieces of candy and Byron ate 7 times as much. According to the given scenario, we can represent this mathematically as:
Mark ate 5 pieces of candy. Byron ate 7 times as much candy as Mark did. To find out the total pieces of candy Byron ate, we multiply the number of candies Mark ate by 7. Therefore, Byron ate 5 pieces × 7 = 35 pieces of candy.
This arithmetic calculation shows us Byron's total candy consumption during the movie.
what is 0.012 as a fraction
To convert 0.012 to a fraction, you multiply by 1000 to get 12/1000 and then simplify it to 3/250. Therefore, 0.012 as a fraction is 3/250.
To convert the decimal 0.012 into a fraction, follow these simple steps:
Write down 0.012 as 0.012/1.
Multiply both the numerator and the denominator by 1000 to get rid of the decimal point:
0.012 x 1000 / 1 x 1000 = 12 / 1000.
Simplify the fraction by finding the greatest common divisor (GCD) of 12 and 1000, which is 4:
(12 ÷ 4) / (1000 ÷ 4) = 3 / 250.
Thus, 0.012 as a fraction is 3/250.

Step-by-step explanation:
Aaron needs 24 inches of copper wire for an experiment. The wire is sold by the centimeter. Given that 1 inch = 2.54 centimeters, how many centimeters of wire does Aaron need? Hint: 1/2.54 = 24/x , remember you have to keep inches on top and centimeters on bottom of both fractions so they are equal. What is the answer to this problem? PLS HURRY
[tex]\frac{1}{2.54} =\frac{24}{x}[/tex]
Multiply both sides by 2.54.
[tex]1=\frac{24}{x} (2.54)[/tex]
[tex]= \frac{60.96}{x}[/tex]
Multiply both sides by x.
x = 60.96
Hence, Aaron needs 60.96 centimeters of wire.
Final answer:
Aaron needs 60.96 centimeters of copper wire for his experiment, calculated by multiplying 24 inches by the conversion factor of 2.54 cm/inch.
Explanation:
Aaron needs to convert 24 inches of copper wire to centimeters. Since 1 inch equals 2.54 centimeters, Aaron can calculate the length of wire needed by multiplying the number of inches by the conversion factor. By performing the multiplication 24 inches × 2.54 cm/inch, the result will give the length of wire needed in centimeters.
To find the answer, complete the multiplication:
24 inches × 2.54 cm/inch = 60.96 centimeters.
Therefore, Aaron needs 60.96 centimeters of copper wire for his experiment.

Find the equation of the line that is perpendicular to the line y=-1/3x-1 and passes through the point (1,5)
To find the equation of the line perpendicular to y = -1/3x - 1 and passing through the point (1,5), we use the negative reciprocal of the original slope (which is 3) and the point-slope form to finally arrive at the equation y = 3x + 2.
The student is asking for the equation of a line that is perpendicular to a given line and passes through a specific point. The given line has the equation
y = -1/3x - 1. Because perpendicular lines have slopes that are negative reciprocals of each other, the slope of the line we're looking for is 3. Using the point-slope form of the equation of a line, we plug in the slope and the coordinates of the point (1,5) to get
y - 5 = 3(x - 1).
Simplifying this equation gives us the standard form of the line:
y = 3x + 2.

A garage door opener has a ten number keypad. Codes to open the door must consist of 5 digits with no adjecent digits the sane. How many codes are possible?
1st slot: 10 possibilities
2nd slot: 9 possibilities
3rd slot: 9 possibilities
4th slot: 9 possibilities
5th slot: 9 possibilities
10 * 9 * 9 * 9 * 9 = 65610 Possibilities
The total number of possible 5-digit codes for the garage door opener, where no two adjacent digits are the same, is 59,049.
Explanation:This is a combinatorics problem in mathematics. A simple way to solve this problem is to calculate the total number of 5-digit code combinations possible without any constraint, which is 10^5 = 100,000.
However, the condition given in the problem is that no two adjacent digits can be the same. The possible codes for the first digit are 10 (0-9). For the second digit, because it cannot be the same as the first, there are 9 possibilities, the third digit also has 9 possibilities because it cannot be the same as the second, and so on.
Therefore, the total number of possible codes is 10 * 9 * 9 * 9 * 9 = 59,049. Hence, the garage door opener can have 59,049 different codes.

Answer:
[tex](0.80)120[/tex]
Step-by-step explanation:
We are asked to find an expression that represents 80% of 120.
We know that % means per hundred. 80% would be 80 divided by 100.
[tex]80\%\text{ of }120=\frac{80}{100}\times 120=(0.80)120[/tex]
Therefore, the expression [tex](0.80)120[/tex] represent 80% of 120.

You work 20 hours a week at a store in our $8.50 per hour. At another job you earn $8.00 per hour and can work as many hours as you want. If you want to earn $370 for the week, how many hours will you need to work at the second job?
For the second job you work for $8.00 per hour and you want to make $370 for the week so its just simple division.
$370/$8.00 is 46.25 hours a day which means you will have to work close to 46-47 hours a day to make $370 in a week.
