The student council is organizing a school fair. Council members are making signs to show the prices for admission and for each game a person can play. If the school admission is $2 and the price per game is 25 cents, Let x represent the number of games. Which expression can you use to determine the total amount (in dollars) a person pays for admission and playing x games?
Answer:
$2 + 0.25x
Step-by-step explanation:
The expression would be
Let us assume the x be the number of games
And the school admission is $2 plus the price of game is 25 cents
So, based on the above information
The expression to determine the total amount is
= $2 + 0.25x

Can someone pls factor the trinomial
I will mark you as brainliest
find the value of x and please show how
Answer:
x = 12°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
So,
39° + 53° + 4° + 7x = 180°
Add all the numbers on the left up.
96° + 7x = 180°
Subtract 96 from both sides.
7x = 84°
x = 12°
Hope this helps!
Answer: x= 12
Step-by-step explanation:
Triangle angle sum theorem says that the interior angles of a triangle sum to 180 degrees. Set the sum of all of these angles equal to 180 to solve. 39+53+ (4+7x) = 180. Combine like terms. 96 +7x = 180. Subtract 96 from both sides. 7x = 84. Divide both sides by 7. X = 12
Mary bought more than 72 pencils to distribute to children at an orphanage. She packs these pencils in gift boxes.
If she packs 4 pencils each into x gift boxes, the inequality that represents this situation is
.
The simplified form of the inequality is
Answer:
4x≥=72
Step-by-step explanation:
1. Particularly, we have:
Given:
X: number of gift boxes
2. We then have to write the inequation that models the problem:
"Mary bought more than 72 pencils"
"She packs 4 pencils each into x gift boxes"
Finally we have:
4x≥=72, for the inequality that represent this situation.
When Simplfying (simplified form):
= x≥72/4
= x≥18
Answer:
4x > 72
x > 18

oh god does anyone understand this? I need help it’s for a test and I wanna do good!!
Answer:
A
Step-by-step explanation:
Its a right angle, so you have to use trigonometry.
To find x , you use sin60° = opposite/hypotenuse
opposite = x and hypotenuse = 5 . So,
sin60°= x/ 5
5sin60° = x
put the value into your calculator you ' ll get:
[tex] x = \frac{5 \sqrt{3} }{2} [/tex]
To find y, cos60°= adjacent/hypotenuse
adjacent= y and hypotenuse = 5. So,
cos60°= y/5
5cos60°=y
[tex]y = \frac{5}{2} [/tex]

Answer:
5.4
Step-by-step explanation:
First find the area of the square.
L times W
5 times 5=25
Now find the area of the cricle
A=[tex]\pi[/tex][tex]r^{2}[/tex]
Substitute pi with 3.14 and radius with 2.5
A= 3.14 times[tex]2.5^{2}[/tex]
A=3.14 times 6.25
A=19.625
Now substract the area of the square from the area of the circle
Your answer will be 5.375
The rounded answer will be 5.4

If Nathan already has $90 then you would add the amount of money collected after the 4 weeks. In each week he makes $10.
The equation would be $90+($10x4)= $X
what is the unknown angle of a polygon with other angles 85 degrees and 65 degress , first correct answer will become the brainleyest
Answer: 30 degrees
Step-by-step explanation:
Assuming this is a three sided polygon, this would make it a triangle. Interior angles of a triangle sum to 180 degrees. 85+65+u=180
150 + u = 180
U = 30 degrees

8 times a certain number is added to 5 times a second number to give 184.the first number minus the second number is -3.find these number .
Answer:
The numbers are 13 , 16
Step-by-step explanation:
First number be x
Second number be y
x - y = -3 --------------------(I)
x = -3 +y
8x + 5y = 184 ---------------(II)
substitute x = -3 + y in equation(I)
8*(-3 + y) + 5y = 184
-24 + 8y + 5y = 184
-24 + 13y = 184
13y = 184 + 24
13y = 208
y = 208/13
y = 16
Plugin y = 16 in (I)
x - 16 = -3
x = -3 +16
x = 13

PLEASE HELP QUICKLY!!
Answer:
79
Step-by-step explanation:
Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.
