Step-by-step explanation:
Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.
He has 72 pencils and 24 calculators and he must use all of the pencils and calculators.
If Zayed creates the greatest number of identical packages possible, how many pencils will be in each package?
Answer: 3 Pencils
Step-by-step explanation:
In order to know how many packages Zayed can make, we need a number that is a factor of 72 and 24, so that the 72 pencils and the 24 calculators can be divided evenly.
So, if there wre 2 packages, there would be 72 / 2 = 36 pencils 24/ 2= 12 calculators in each package. This creates packages, but isn't the gratest number of packages!
To find the greatest number of identical packeges, we want to found the greatest common factor of 72 and 24
To do so, lets find the factors of 72 and 24
72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
24: 1, 2, 3, 4, 6, 8, 12, 24
the gratest common number factor of 72 and 24 is 24. in math notation this looks like:
gcf (72, 24)=24
the gratest number of identical packages can make is 24
To find the umber of pencils in each pacage, we need to dovide the total number of pencils by the number of pakages:
72 / 24 = 3.
there will be 3 pencils each package

What is Distributive Property?The distributive property is also known as the distributive law of multiplication over addition and subtraction. The name itself signifies that the operation includes dividing or distributing something. The distributive law is applicable to addition and subtraction. Let us learn more about the distributive property in this page.
The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC. This distributive law is also applicable to subtraction and is expressed as, A (B - C) = AB - AC. This means operand A is distributed between the other two operands.
Given:
48 + 72
Now, factorize the above into prime factors
48 = 2 x 2 x 2 x 2 x 3
and, 72 = 2 x 2 x 2 x 3 x 3
Now, rewriting
48 + 72
= 2 x 2 x 2 x 2 x 3 + 2 x 2 x 2 x 3 x 3
= 2 x 2 x 2 x 3 (2 + 3)
=24 (2+3)
Hence, the expression can be written as 24 (2+3).

What value of x is in the solution set of 2(3x – 1) > 4x – 6?
It could only be the following :
A. -10
B. -5
C. -1
D. -3
Answer:
-1
Step-by-step explanation:
Given the equation :
2(3x – 1) > 4x – 6
Open the bracket :
6x - 2 > 4x - 6
Collect like terms
6x - 4x > - 6 + 2
2x > - 4
Divide both sides by 2
2x /2 > - 4/2
x > - 2
Since x > - 2
-10, - 5, - 3 are all < - 2
Hence, the only option greater than - 2 is - 1

Out of 153 students appeared in an examination the ratio of the students who got the A+ A and B+ grades is 2:4:5 and if 21 students got the other grades then, how many students got the A+, A and B+ grades?
Step-by-step explanation:
153 - 21 = 132
132 / 11 = 12
Hence 24 students got A+, 48 students got A, and 60 students got B+.

Step-by-step explanation:
In order to solve one side length of a right triangle given two of other side lengths, you can use the pythagorean theory.
The theory states that the sum of the two adjacent side squares equals the square of the hypotenuse.
Basically:
[tex]x^2 + y^2 = h^2[/tex]
Since the problem gives you the hypotenuse and one adjacent side length you rearrange the formula as so:
[tex]x^2 = h^2 - y^2[/tex]
[tex]x=\sqrt{h^2 - y^2}[/tex]
Then plug in the values:
[tex]x = \sqrt{16^2 - 10^2} = \sqrt{256-100}=\sqrt{156} = 2\sqrt{39}=12.489996[/tex]
Jonah and his sister are going to the amusement park. They each purchase 2 tickets at $1.25 each. Then, they each get a soda for $3.50 a piece. How much did they spend all together?
Answer:
$12.00 all together.
Step-by-step explanation:
there is only 2 people him and his sister.
They both purchase 2 ticket for $1.25
so 4 tickets all together
1.25x4=$5
They they both get one soda for $3.50
$3.50+$3.50=$7
$7+$5=12
So they spent $12
1995. Were 57 million cats as pets in the U.S. By 2003this number was 61 millionWrite a linea model for the number of cats as pets. Then use the model to predict the number of cats as pets in 2015
Answer:
Cats as pet in 2015 = 6 million
Step-by-step explanation:
Given:
Cats as pet in 1995 = 57 million
Cats as pet in 2003 = 61 million
Find:
Cats as pet in 2015
Computation:
Difference in year = 2003 - 1995
Difference in year = 8 year
Difference in year = 2015 - 2003
Difference in year = 2015 - 2003
Difference in year = 12 year
Difference in number = 61 - 57
Difference in number = 4 million
So,
Cats as pet in 2015 = 4 million x [12/8]
Cats as pet in 2015 = 6 million

Answer:
x = 1.155
x = -1.155
Step-by-step explanation:
4x² = x² + 4
i) move variable to the left-hand side and change its sign4x² - x² = 4
ii) collect like terms3x² = 4
iii) divide both sides of the equation by 3[tex] \frac{ {3x}^{2} }{3} = \frac{4}{3} [/tex]
[tex] {x}^{2} = \frac{4}{3} [/tex]
iv) take the square root to the opposite side of the equation and remember to use positive and negative roots[tex]x = + - \sqrt{ \frac{4}{ 3} } [/tex]
v) the equation has two solutions. write the solutions, one with a '+' sign and another with a '-' sign[tex]x = \sqrt{ \frac{4}{3} } \: or \: 1.155[/tex]

Step-by-step explanation:
the numbers skip by 20
Answer:
-4
Step-by-step explanation:
If you look at the table closely for the value of x decreases by 2 like the first value is 7 then it goes to 5 then it goes to 3 then to 1, and if you look at the values of y it decreases by 20 like the first number is 66 then 46 then 26 then 6.
But in the table it asks the missing value of y when x is 0 not -1 so for difference of 1 instead of the usual 2 in the pattern the value of y would decrease by 10 instead of 20 so 6-10 would be -4
so the missing value of y is -4

Chuck and Holly are saving money to buy a car. Chuck has $500 already and is going to save $100 a month. Holly has $1000 and plans on saving $50 a month. In the space to the left, write an equation that shows when Chuck and Holly will have the same amount of money. What is the equation
Answer:
10 months
Step-by-step explanation:
Step one
Given
Chuck has $500
Chuckle wants to save $100 monthly
Let the number of months be x
And the total be y
So
Y=500+100x--------1
Holy has $500
Chuckle wants to save $500 monthly
Let the number of months be x
And the total be y
So
Y=1000+50x--------2
Equate 1 and 2
500+100x=1000+50x
1000-500=100x-50x
500=50x
x=500/50
x=10
Mae earns a weekly salary of $330 plus a commission of 6.0% on a sales gift shop.How much would she make if she sold $4300 worth of merchandise?
Answer:
Total income = $588
Step-by-step explanation:
Given:
Weekly salary = $330
Commission = 6%
Total sales = $4,300
Find:
Total income
Computation:
Total commission = $4,300 x 6%
Total commission = $258
Total income = Weekly salary + Total commission
Total income = $330 + $258
Total income = $588
