Please do 24 1/2 - 19 5/8
Answers
In order to do that, multiply the whole number by the denominator and add it to the numerator.
That would make 24 [tex] \frac{1}{2}[/tex] into [tex] \frac{49}{2} [/tex].
Also, it'd make 19 [tex] \frac{5}{8}[/tex] into [tex] \frac{157}{8} [/tex].
Now that they're both improper fractions, you need to make them have a common denominator in order to actually subtract them. You can do that by multiplying the numerator and denominator of [tex] \frac{49}{2} [/tex] by 4, to make it stay the same fraction, but have the same denominator as [tex] \frac{157}{8} [/tex].
[tex] \frac{49}{2} = \frac{196}{8} [/tex]
Now we can subtract them!
[tex] \frac{196}{8} - \frac{157}{8} = \frac{39}{8} [/tex]
When subtracting fractions, only subtract the numerators. You don't subtract the denominators.
The final answer is [tex] \frac{39}{8} [/tex]

Solve the inequality and describe the solution set:
y-6 ≥ 12
Answers
You want to get the y only on one side of the equation. To get rid of the -6 you have to add 6 to both sides to even out the equation.
y-6≥12
+6 +6
y ≥18
Answer: The solution set is y≥18.
Step-by-step explanation:
Since we have given that
[tex]y-6\geq 12[/tex]
We need to first find the inequality and find the solution set.
[tex]y-6\geq 12\\\\y\geq 12+6\\\\y\geq 18[/tex]
So, the solution set for this would be all the values of y which is greater than 18.

Substitute that into,
[tex]x = 49 - 21 \\ x = 28[/tex]
Answer check :
[tex]21 + 28 = 49 \\ 28 + 2(21) = 28 + 42 = 70[/tex]
Answer : The numbers are 21 and 28.
Hope this helps. - M
The problem is solved using a system of equations to find that the two numbers in question are 21 and 28.
To solve the problem involving two numbers where the sum equals 49 and the sum of the larger number and twice the smaller number equals 70, we need to form a system of linear equations and solve for the unknowns. Let's denote the smaller number as s and the larger number as l.
The sum of the two numbers is 49: s + l = 49.The sum of twice the smaller number and the larger number is 70: 2s + l = 70.Subtract the first equation from the second to find the value of s.
2s + l - (s + l) = 70 - 49
Which simplifies to:
s = 21
Substitute the value of s into the first equation:
21 + l = 49
And solve for l:
l = 28
Therefore, the smaller number is 21 and the larger number is 28.

Brianna took out a car loan for $12,250 that has a 0% APR for the first 20 months and will be paid off with monthly payments over a 4 years. For how many months will Brianna be charged interest.
Answers
Final answer:
Brianna will be charged interest for 28 months.
Explanation:
To determine how many months Brianna will be charged interest, we need to first calculate the total number of months she will be making payments. Since there are 4 years in total, and each year has 12 months, the total number of months is 4 years * 12 months/year = 48 months.
For the first 20 months, Brianna has a 0% APR and will not be charged interest. So we subtract these 20 months from the total number of months to find out how many months she will be charged interest: 48 months - 20 months = 28 months.
Therefore, Brianna will be charged interest for 28 months.
Ms. Ito's art class used 2/3 of bottle of blue paint. If they used 1/4 as much red paint as blue paint. How many bottles of red paint did they use?
Answers
Final answer:
The class used 2/3 of a bottle of blue paint and 1/4 as much red paint, which means they used 1/6 of a bottle of red paint.
Explanation:
To solve the problem presented by Ms. Ito's art class, we first need to determine the amount of blue paint used and then calculate the red paint used based on that amount. The class used 2/3 of a bottle of blue paint. Since they used 1/4 as much red paint as blue paint, we need to divide the amount of blue paint by 4 to find the amount of red paint used.
Calculation: (2/3) ÷ 4 = 2/3 ÷ 1/4 = (2×1)/(3×4) = 2/12 = 1/6
Therefore, the class used 1/6 of a bottle of red paint.

Kara and Steven are biking around a 1,800 kilometer path. They start biking from the same place, at the same time, and in the same direction. Kara bikes at a speed of 15 km/h and Steven bikes at a speed of 30 km/h. How long will it take before Steven and Kara will be at the same place of the path next time?
Answers
Time taken before the cyclist are on the same sport will be found as follows:
time=distance/(relative speed)
distance=1800 km
given that the cyclist will be riding towards the same side, then
relative speed=(Steve's speed-Kara's speed)=30-15=15 km/h
thus time taken will be:
time=1800/15
=120 hours

Let n be the number of students in 5th grade; n-10 is the number of students in 2nd grade.

you flip two coins and roll a number cube what is the probability of flipping two tails and rolling as even number

Answer: 1/8
so 1/2 x 1/2 = 1/4 probability of getting 2 tails
a single die has 3 even numbers so you have a 3/6 = 1/2 probability of getting an even number
multiply both together for probability of 2 tails and an even number: 1/4 x 1/2 = 1/8 probability
