A vendor sells hot dogs and bags of potato chips. A customer buys 3 hot dogs and 5 bags of potato chips for $9.50. Another customer buys 2 hot dogs and 5 bags of potato chips for $8.00. Find the cost of each item.
Step-by-step explanation:
3d + 5p=9.50
2d + 5p=8
1 hot dog cost $1.50
2 × 1.50 + 5p = 8
3 + 5p = 8
5p = 8 - 3
5p = 5
p = 1
1 bag of potato chips cost $1.00

I couldn’t figure this probably out. Please help
Answer:
x = 9
Step-by-step explanation:
Perimeter of rectangle = 2(l+b) = 42
=> 2(x+3 + x)
=> 2 (2x + 3) = 42
=> 4x + 6 = 42
=> 4x = 42 - 6
=> 4x = 36
=> x = 36/4
=> x = 9
Hope it helps :)
Answer:
Formula = (l + b) x 2= 42 so answer = x=9
Step-by-step explanation:
l =x
b =x+3
( x+x+3) * 2 =42
2x +3 x 2 = 42
2x +3 = 42/2
2x +3 = 21
2x = 21 - 3 =18
x = 18/2
x=9

What is the y=mx+b of the equation 3x−2y=12
Answer:
y=3/2x-6
Step-by-step explanation:
To find the y=mx+b you need to move the y on one side while moving the others on the other side
First, move the 3x to the other side by subtracting by 3x on both sides:
-2y=-3x+12
Divide by -2 on both sides:
y=3/2x-6
Answer:
y=3/2x-6
Step-by-step explanation:
3x-2y=12
isolate the y:
-2y=-3x+12
get rid of the coefficient in front of y by dividing by -2
y=-3/-2x+12/-2
y=3/2x-6

Answer:
6. 60
7. 24.25
8. 28.00111604 or 28
Step-by-step explanation:
30 +90 =120 180-120=60
Sin A = a/c, so a = cSin A. Also Cos A = b/c, so b = cCos A so Sin30=14/c=28
Cos30=b/28 b=24.25
now 14^2+24.25^2=c^2 which gives 28.00111604 or 28

Answer:
c) [tex]h(t)=-16(t-1.5)^{2}+676[/tex]
Step-by-step explanation:
Each of the given equations is written in vertex form. This means that the vertex is written in the equation. The quadratic term (the term to the second degree), contains (x), and a value that is either added or subtracted to it. The additive inverse (meaning a number times negative one) of that number is the x-coordinate of the vertex. Therefore, the term inside the parenthesis is (-1.5). The constant is the y-coordinate of the vertex, and therefore it is 676. Since the object is being thrown off a cliff, gravity acts on it. The gravitational constant in feet per second is (-16), hence the coefficient of the quadratic term is (-16).

Answer:
8
Step-by-step explanation:
If the area is 32 and the formula for area of a triangle is base * height / 2, and you have base = 8 and height = x and area = 32, this would be:
8 * x / 2 = 32
Now, solve:
[tex]8x/2=32\\4x=32\\x=8[/tex]
Answer:
x=8
Step-by-step explanation:
Area is equal to half of the base times the height. We are told that the area is 32and the base is 8, so we can write this equation:
32=1/2(8)h
Multiply 1/2 by 8:
32=4h
Divide both sides by 4:
h=8
So now we know that x (the height) equals 8.

Renee is creating a diagram to prove that a certain triangle is a right triangle. In her diagram, she uses three white quadrilaterals that are squares. Which diagram could be the one that Renee is creating
Answer:
Option D
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.
A right angled triangle is a triangle in which one of the angles is 90°. The side opposite the 90° is known as the hypotenuse while the remaining sides is known as the leg. Let us assume a right triangle with legs of a, b and a hypotenuse of c. Then using Pythagoras theorem:
c² = a² + b²
From the options, option d is the correct option.
For option D, the hypotenuse is c and one leg is a. Let x represent the second leg. Hence:
c² = a² + x²
x² = c² - a²
x = √(c² - a²)
Therefore the other leg would be √(c² - a²)

For the 1,000-meter running event, Abby's mean time is 4.5 minutes with a standard deviation of 0.75 minutes. For the 800-meter event, Abby's mean time is 3.2 minutes with a standard deviation of 0.4 minutes. In the last track meet, Abby ran the 1,000-meter race in 4.1 minutes and the 800-meter race in 3 minutes. In which event did Abby have a better performance?
Answer:
He performed better in the 800 m race
Step-by-step explanation:
Obtain the standardized score for each event :
Zscore = (score - mean) / standard deviation
1000 meter :
Mean = 4.5 ; Standard deviation = 0.75 ; x = 4.1
Zscore = (4.1 - 4.5) / 0.75
Zscore = - 0.4 / 0.75 = - 0.5333
800 meter :
Mean = 3.2 ; Standard deviation = 0.4 ; x = 3
Zscore = (3 - 3.2) / 0.4
Zscore = - 0.2 / 0.4 = - 0.5
-0.5 > - 0.533
Hence, he performed better in the 800 m race
Answer:
Abby had a better performance in the 800-meter because this z-score was closer to the mean than the z-score for the 1,000-meter.

Help ASAP
Answer:
14
Step-by-step explanation:
Answer:
(x, y) = (-16/5, 13[tex]\frac{1}{5}[/tex])
Step-by-step explanation:
4x + 9y = 24
x + y = 10 $\Rightarrow$ x = 10 - y
Substituting the value of x (second equation) into the first equation, we get:
4 * (10 - y) + 9y = 24
40 - 4y + 9y = 24
5y = -16
y = -16/5.
So, x = 10 - (-16/5) = 10 + 3[tex]\frac{1}{5}[/tex] = 13[tex]\frac{1}{5}[/tex]
What’s the value of x
Answer:
C. x=42
Step-by-step explanation:
16 + 3x + y = 180
126 + 16 + y = 180
y = 38
16 + 3x + 38 = 180
54 + 3x = 180
3x = 126
x=42
