Toby picks a 4-digit number.
It is larger than 7999 and it is a multiple of 5.
How many different numbers could he have picked?
Answer:
Total different numbers = 400
Step-by-step explanation:
Assume;
Smallest number bigger than 7999( multiple of 5) = 8,000
largest 4 digit number multiple of 5) = 9,995
Computation:
a = 8,000
d = 5
an = 9,995
an = a + (n-1)d
9,995 = 8,000 + (n-1)5
1,995 = (n-1)5
399 = n-1
n = 400
Total different numbers = 400
2x - 3y --24
x + 6y = 18
Substitution
Answer:
y=12
x=30
Step-by-step explanation:
2x-3y=24 ... 1
x+6y=18 ... 2
2*2:
2x+12y=36...3
3-1:
y=12
x=30
When the following system of equations 2x - 3y = -24 and x + 6y = 18 are solved, the value of x and y is found to be -6 and -4 respectively.
Mathematically, an equation is a statement that asserts the equivalency of two expressions. It consists of two hands, the left-hand side( LHS) and the right-hand side( RHS), separated by an equal sign( =). The LHS and RHS can be numbers, variables, constants, or further complex fine expressions.
Given the system of equations:
2x - 3y = -24 (equation1)
x + 6y = 18 (equation2)
From equation 2,
x = 18 - 6y
Now, substitute this expression for x in equation (1):
2(18 - 6y) - 3y = -24
36 - 12y - 3y = -24
36 - 15y = -24
-15y = -60
y = [tex]\frac{(-60)}{(-15)}[/tex]
y = 4.
Now substitute it back into equation (2) to solve for x:
x + 6(4) = 18
x + 24 = 18
x = 18 - 24
x = -6
Therefore, the solution to the system of equations is x = -6 and y = 4.

Members of a lacrosse team raised $1352.50 to go to a tournament. They rented a bus for $802.50 and budgeted $25 per player for meals. Write and solve an equation which can be used to determine p, the number of players the team can bring to the tournament.
Answer: 22
Step-by-step explanation:
From the question the, we are informed that members of a lacrosse team raised $1352.50 to go to a tournament and that they rented a bus for $802.50 and budgeted $25 per player for meals.
The equation which can be used to determine p, the number of players the team can bring to the tournament would be calculated as:
802.50 + 25p = 1352.50
25p = 1352.50 - 802.50
25p = 550
p = 550/25
p = 22
They can bring 22 players to the tournament

A library had 570 books when it first opened. A year later, the number of books increased by 30%. How many books were there in the library a year later?
Answer: There were 741 books in the library a year later.
Step-by-step explanation:
Given: Total books in library = 570
Number of books increased by 30%.
One year later, Number of books in the library = (Total books in library) + 30% x (Total books in library)
= 570 + (0.30) x (570)
= 570 (1+0.30)
= 570 (1.30)
= 741
Hence, there were 741 books in the library a year later.

If a university accepts only 75 percent of applicants, and only 45 percent of accepted applicants enroll, what percentage of total applicants enroll
Answer = 33.75%
Step-by-step explanation: It might be intuitive to think of percentages as a part of 100. If only 75 percent of 100 applicants are accepted. Then 75 people are accepted. We now need to find 45 percent of 75 people. In order to do this we need to convert 45 percent into its decimal form and multiply it by 75.
.45*75 = 33.75 of the original 100 Applicants have enrolled.

If a point O(x, y) divides a line segment AB with end points at A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2[/tex]) in the ratio of n:m, then the location of O is at:
