A baseball team is having an end of the year party and the coach wants to purchase gloves and baseballs for the team. Gloves are sold in cases of 8 and baseballs are sold in cases of 12. The coach wants to buy the exact same number of gloves as baseballs.What is the least number of gloves and baseballs he would have to purchase to have the same number of each?
Answer: 24 is the least number of gloves and baseball need to purchase .
Step-by-step explanation:
Given: Gloves are sold in cases of 8 and baseballs are sold in cases of 12.
To get the exact same number of gloves as baseballs, the least number of gloves and baseball need to purchase = L.C. M. (8,12)
[L.C.M.= Least common multiple]
Since 8 = 2 x 2 x2
12 = 2 x 2 x 3
So, L.C. M. (8,12) = 2 x 2 x 2x 3 = 24
Hence, the least number of gloves and baseball need to purchase = 24

Simplify −9 + 1/4x − 6 − 1/8x.
Answer:
- 72x-1 /8x
Step-by-step explanation:
Answer: -15+1/8x
Step-by-step explanation:
-9+1/4x-6-1/8x
You must add the 9 and 6 because they are both negative numbers and you get -15. You would multiply 1/4 by two in order to subtract 1/4 from 1/8. You would have 2/8-1/8 which would get you 1/8.
The GCF of the numerator and denominator in 15/24 is _____.
8
3
2
5
Answer:
3
Step-by-step explanation: 8 can go into 24 perfectly but not 15 and 5 can go into 15 perfectly but not 24 but 24/3 is 8 and 15/3 is 5
You might say two could do the same thing which is true but we are talking about the GCF, they are asking for the greatest common factor so that's why the answer is 3
Answer:
3
basically, 8 can go into 24 exactly but 15 and 5 can not go into 15 perfectly neither can 24. 24/3 is 8 and 15/3 is 5
You might say two could do the same thing which is true but we are talking about the GCF, they are asking for the greatest common factor so that's why the answer is 3 :D
What is the answer to
-4 ( 5x + 3)
Answer:
-20x - 12
Step-by-step explanation:
times -4 by everything inside the bracket
-4 times 5x = -20x
-4 times +3 = -12
-4(5x+3) = -20x - 12
(a positive times a negative is a negative)

Which inequality represents the following statement?
"A number increased by 4 is at most 15."
Answer:
x + 4 ⩽ 15
Step-by-step explanation:
Let
The number = x
At least in inequality is ⩾ (greater than or equal to sign)
At most in inequality is ⩽ ( less than or equal to sign)
A number increased by 4 is at most 15.
x + 4 ⩽ 15
The inequality that represent the statement is x + 4 ⩽ 15
x + 4 ⩽ 15
x ⩽ 15 - 4
x ⩽ 11

If you can type 50 words per minute, how many minutes would it take you to type a 500 word essay
==========================================
Work Shown:
A = 50 = number of words typed in 1 minute
B = 1 minute
C = 500 words
D = x minutes (needed to type 500 words)
A/B = C/D
50/1 = 500/x
50*x = 1*500 ... cross multiply
50x = 500
x = 500/50 .... divide both sides by 50
x = 10
You'll need 10 minutes to type 500 words
------------
Alternative approach:
50 words = 1 minute .... given speed
1 word = 1/50 minute ... divide both sides by 50
1 word = 0.02 minute
500 words = 10 minutes .... multiply both sides by 500
As per the given data, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.
If you have a typing speed of 50 words per minute, it means you can accurately type 50 words in one minute. This rate is often considered an average typing speed for proficient typists.
If I can type 50 words per minute, then to determine the number of minutes it would take to type a 500-word essay, we can divide the total number of words by the typing speed:
Time (in minutes) = Total words / Typing speed
Time = 500 words / 50 words per minute
Time = 10 minutes
Therefore, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.

Step-by-step explanation:
y= -16 (total amount of meters below ground)
m= -1.5 (slope; meters he descends per minute)
x= 6 (minutes)
b= -7 (starting point)
thus; y= -1.5x-7
because; -16=(-1.5)(6)-7

Suppose that the number of bacteria in a certain population increases according to an exponential growth model, with a growth rate of 19% per hour. Suppose also that a sample culture of 2300 bacteria is obtained from this population. Find the size of the sample after five hours. Round your answer to the nearest integer.
Answer: 5489
Step-by-step explanation:
Given the following :
Growth rate (r) = 19% per hour
Sample culture in population = 2300
Size of sample after 5 hours =?
Using the exponential relation:
P = Po * r^t
P = population after 5 hours
Po = Initial sample population
t = time
P = 2300 * (1 +19%)^t
P = 2300 ×(1 + 0.19) ^5
P = 2300 * 1.19^5
P = 2300 * 2.3863536599
P = 5488.61341777
P = 5489 (nearest integer)

i will give brainliest
Answer:
Step-by-step explanation:
∠A and ∠B are vertical => ∠A=∠B
20x+10=30x-10
20x-30x= -10-10
-10x= -20
x= -20 / -10 = 20 / 10 = 2
x=2
Good luck!
Answer:
2
Step-by-step explanation:
Ok remember this because its going to appear alot in geometry. Vertical angles are ALWAYS congruent and congruent means when two things are equal/ are the same.
If angle a and b are vertical angles what does that mean?
they are CONGRUENT!
you know A = 20x+ 10 and B= 30x-10
so you can write it as
20x+10 = 30x-10
because Angle A and B equal each other
then get the variable by itself so subtract -20x on both sides
10 = 10x-10
then add 10 to both sides which is
20 = 10x
and divide 10 on both side and 20 divided by 10 is 2
so 2 =x
which is the same as x =2
