Answer:
The cost of soft pretzel is $1.25
Step-by-step explanation:
Let $x be the price of one slice of pizza and $y be the price of one soft pretzel.
1. 9 slices of pizza cost $9x and 5 soft pretzels cost $5y. Together they cost $33.25, then
9x+5y=33.25.
2. 4 slices of pizza cost $4x and 6 soft pretzels cost $6y. Together they cost $19.50, then
4x+6y=19.50.
3. Solve the system of two equations:

Multiplythe first equation by 4, the second equation by 9 and subtract them:

Then

The cross-section cut by the plane yields a quadrilateral with length and width equal to the length and width of the face that is parallel to the plane.
Cos^2 + cos^2 tan^2 (break the brackets)
Cos^2+ cos^2 • sin^2/cos^2 (divide out the cos^2)
Cos^2+ sin^2 (Cos2+ sin^2= 1)
= 1
<h2><u>solución</u></h2>
deja que los números sean x, and x + 2
sabemos que su suma es igual a 100, entonces
por lo tanto, el primer número es 49
y el segundo número es x + 2 = 49 + 2 = 51 (también es el mayor entre los dos números)
entonces suma de dígitos de mayor número = 5 + 1 = 6
Respuesta correcta de la pregunta anterior = 6
