A book store is hosting a special night in which families can enjoy a story and craft time. Tickets to the
event must be purchased ahead of time and are $1.50 for children and $2.50 for adults. So far, 45
children's tickets have been sold, which is 60% of the total tickets sold. How many tickets have been
sold so far? Show your calculations or explain how you got your answer.
Answer:
75 total tickets
Step-by-step explanation:
METHOD 1:
We know that 45 children's tickets have been sold, being 60% of the total tickets having been sold.
So, basically, we solve for x:
We have, 60% × x = 45
or, 60/100 × x = 45
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 45 × 100/60
x = 75
If using calculator, enter 45x100/60, which will give you the answer.
------------------------
METHOD 2:
Division is the opposite of multiplication
Start with the formula to calculate the percentage of total
y=value÷ percentage/100
Substitute values in the equation
y=45÷60/100
Simplify and solve
y=45÷0.6
y=75
Both methods give you 75, therefore 75 tickets have been sold

write an equation using x and y to represent the hanger.
Answer:
Step-by-step explanation:
Givens
The triangle is x
The square is y
Left side
x + 3y is the weight
Right side
4x + y is the weight.
The weights are equal because the hanger is balanced.
Balance equation
x + 3y = 4x + y Subtract x from both sides
x-x + 3y = 4x-x + y Combine
3y = 3x + y Subtract y from both sides
3y - y = 3x + y - y Combine
2y = 3x
Answer
2y = 3x
Answer:
x +3y = 4x +y
Step-by-step explanation:
A hanger diagram like this is intended to show you that the total weight on the left side is equal to the total weight on the right side.
__
left sideThe left side shows 1 triangle and 3 squares. x and y are defined as the weights of the triangle and square, respectively, so the weight on the left side can be represented as ...
x + 3y
right sideThe four triangles and 1 square on the right can have their total weight represented as ...
4x +y
balanceThe intent of the diagram is to show that the left-side weight is equal to the right-side weight. That equality can be written as ...
x +3y = 4x +y
_____
Additional comment
This problem is not asking for any sort of "solution" or relationship between x and y. We could find such a relationship by solving the equation for y:
x +2y = 4x . . . . subtract y from both sides
2y = 3x . . . . . . . subtract x from both sides
y = (3/2)x . . . . . divide by the coefficient of y
This tells you that the hanger will only be balanced if the weight of a square is half-again as much as the weight of a triangle.

tysm!!!
Step-by-step explanation:
Let x, and x+1 be the consecutive numbers.
[tex]x + (x + 1) = 37[/tex]
[tex]2x + 1 = 37[/tex]
[tex]2x = 36[/tex]
[tex]x = 18[/tex]
Plug in 18 for x+1,
[tex]18 + 1 = 19[/tex]
So the numbers is 18,19
Answer:
18 and 19
Step-by-step explanation:
if you have two consecutive numbers, then using algebra, one unknown number is x and the other unknown consecutive number is x + 1
The equation x + x + 1 = 37
To solve this equation subtract 1 from both sides as one does in algebra.
x + x + 1 = 37 → x + x + 1 - 1 = 37 - 1
Now you have the equation x + x = 36
This can rewrite this as 2x = 36 2x means 2 times the value of x
To solve this part of the equation divide both sides by 2
2x / 2 = 36 / 2
x = 18
The next consecutive number x + 1 = 19, (18) + 1 = 19
check this by adding. 18 + 19 = 37.

Hey there!
PROBLEM #1. 4 * 2,160
4 * 2,160
= 2,160 * 4
= 2,160 + 2,160 + 2,160 + 2,160
= 4,320 + 4,320
= 8,640
Therefore, the answer should be: 8,640
Problem #2. 4 * 2,610
4 * 2,610
= 2,610 * 4
= 2,610 + 2,610 + 2,610 + 2,610
= 5,220 + 5,220
= 10,440
Therefore, the answer should be:
10,440

find the measure of MNI. please help! i’ll give you brainlist!
Answer:
[tex]m\angle MNI = 135^{\circ}[/tex]
Step by step explanation:
[tex]\text{The exterior angle of a triangle = sum of two opposite interior angles.}[/tex]
[tex]~~~~~~\angle MNI = \angle LMN + \angle MLN\\\\\implies 19x+2=(15x-12)+6x\\\\\implies 19x +2 = 21x-12\\\\\implies 21x -19x = 12+2\\\\\implies 2x = 14\\\\\implies x=\dfrac {14}2\\\\\implies x = 7\\\\\text{So,}~ m\angle MNI = 19(7)+2=135^{\circ}[/tex]
