During a football game, the parents of the football players sell pretzels and popcorn to raise money for new uniforms. They charge $2.50 for a bag of popcorn and $2 for a pretzel. The parents collect $336 in sales during the game. They sell twice as many bags of popcorn as pretzels. How many bags of popcorn and pretzels do they sell?
2.5x + 2y = 336
x = 2y
2 equations, 2 unknowns, solvable
3.5x = 336
7x = 672
x = 672 / 7
x = 96
96 / 2 = y
y = 48
they sold 96 popcorn bags and 48 pretzels
If k(x) = 5x – 6, which expression is equivalent to (k k)(4)?.
The expression 5(4) - 6 + 5(4) - 6 is equivalent to (k + k)(4) option fourth is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is:
If k(x) = 5x – 6, which expression is equivalent to (k + k)(4)?
5(4 + 4) – 6. 5(5(4) – 6) – 6. 54 – 6 + 54 – 6. 5(4) – 6 + 5(4) – 6Plug k = 4 in the function:
k(4) = 5(4) - 6
Now,
= (k + k)(4) or
= k(4) + k(4)
= 5(4) - 6 + 5(4) - 6
Thus, the expression 5(4) - 6 + 5(4) - 6 is equivalent to (k + k)(4) option fourth is correct.

Find:
(I) ABD
(II) CBD
Answer:
ABD
Step-by-step explanation:
Mark brainliest today afternoon message was not going that account was deleted
this is my new account ha Aryan hu
From the kite ABCD, ∠ABD = 65° and ∠CBD = 46°
Properties of a kite:Pair of adjacent sides are equalOne pair of opposite angle is equalDiagonals are perpendicular to each otherThe longer diagonals bisect the other diagonal.∠ABC≅∠ADC
∠EDC = 180 - 90 - 44 (sum of angle in a triangle)
∠EDC = 46°
∠EDC ≅∠EBC
∠ADE = 180 - 25 - 90 (sum of angle in a triangle)
∠ADE = 65°
∠ADE ≅ ∠ABD(Base angle of isosceles triangle)
Therefore,
∠ABD = 65°
∠EDC ≅ ∠CBD (Base angle of isosceles triangle)
Therefore,
∠CBD = 46°

5x + 25 + x + 5 = 90
6x + 30 = 90
6x = 90 - 30
6x = 60
x = 10
Solution:
We can see that the 90° angle is divided into two angles. Thus, the sum of two angles must equal 90°.
=> 90 = 5x + 25 + x + 5Combine like terms:
=> 90 = x(5 + 1) + 5(5 + 1)=> 90 = x(6) + 5(6)=> 90 = 6x + 30Subtract 30 both sides:
=> 90 - 30 = 6x + 30 - 30=> 60 = 6xDivide 6 both sides:
=> 60 = 6x=> x = 60/6 = 10The value of x is 10.

Help!! Its A Math Problem ! I am not sure how to solve it!! or show my work
Answer:
Step-by-step explanation:
#1.
2x² + 24x + 10 = 0
2(x² + 12x + 5) = 0
2[ x² + 2(6)x + 6² - 6² + 5 ] = 0
2[(x + 6)² - 31] = 0
2( x + 6 - √31 )( x + 6 + √31 ) = 0
[tex]x_{1}[/tex] = - 6 + √31
[tex]x_{2}[/tex] = - 6 - √31
#2.
f(x) = 3x² - 36x - 12
f(x) = 3( x² - 12x - 4 )
f(x) = 3 [ x² - 2(6)x + 6² - 6² - 4 ]
f(x) = 3 [( x - 6 )² - 40 ]
f(x) = 3( x - 6 )² - 120

find x and y
y= x-5
y= -7x+11
Answer:
x = 2
y = -3
Step-by-step explanation:
make them equal to each other
x-5 = -7x + 11
8x = 16
x = 2
put 2 back in the equation to get y
y = 2 - 5
y = -3
Answer:
x = 2
y = -3
Step-by-step explanation:
Solve using substitution.
Substitute x-5 for y:
x - 5 = -7x + 11
Add 7x to both sides
8x - 5 = 11
Add 5 to both sides
8x = 16
Divide both sides by 8
x=2
Plug 2 back in for x to solve for y:
y = x - 5 = 2 - 5 = -3
(x, y)=(2, -3)
(b) Water flows into the tank at a rate of 30 litres per minute. Calculate the time taken to fill an empty tank. Give your answer to the whole minute. (1 litre = 1000 cm')
Answer:
Step-by-step explanation:
We need to know the volume of the tank. If the volume, X (in liters), is given in cm^3, convert the value to liters (1 liter = 1,000 cm^3). Then take the tank volume and divide by 30 liters/min:
X liters/(30 liters/min) = X/30 minutes

Answer:
C (-5,[tex]\frac{8}{3}[/tex])
Step-by-step explanation:
I uses demos graphing calculator
First, found the slope using point (0,6) and (3,8)
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{8-6}{3-0}[/tex]
m = [tex]\frac{2}{3}[/tex]
m = slope
Now I will be able to form a linear equation:
y = mx + b (is our y-intercept, when x is 0) When x is 0, y is 6 (0,6)
y = [tex]\frac{2}{3}[/tex]x + 6
I graphed that on demos, and that's how I got my final answer.
I would attach the link to the graph, but brainly deleted my answer before. So, try to write that in to demos (y = [tex]\frac{2}{3}[/tex]x + 6) if you want to see the graph.

The girls tennis team was interested in raising funds for an upcoming trip. The team sold tumblers for $10 and sun hats for $5
When the sales were over, the team had earned $190 and sold 30 total products, which included a mix of tumblers and hats.
Let t represent the number of tumblers sold and s represent the number of sun hats sold.
Which equations can be used to represent the situation?
Select two that apply.
t+s=190
10t+5s=30
t+s=30
10t+5s=190
t+s=15
5t+10s=190
The equations that can be used are 10T + 5S = 190 and T + S = 30.

THANK YOU SO MUCH!
Answer:
k=11.111111111111, D=2600/39, A=16.81, C=400, W=27.75, K=10
Step-by-step explanation:
Hope this helped!
If A = 52 and K=22 then D = 63.44 and if Given A = 361 and K = 5 then
C = 398.0025.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, A = 52 and k = 22.
From the diagram, D is (100 + 22)% = 122% of A.
Therefore,
D = (122/100)×52.
D = 63.44.
Given, A = 361 and k = 5.
Therefore,
C = (105/100)×361
C = 379.05 and again 105% of 379.05.
C = (105/100)×379.05.
C = 398.0025
