Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa. Con la cuarta parte del dinero compró una bolsa de palomitas y le sobraron 5 euros. ¿Con cuánto dinero salió de casa?
Answer:
Héctor salió de su casa con 12 euros.
Step-by-step explanation:
Cuando Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa, tenemos:
[tex] C = \frac{1}{3}x [/tex] (1)
Cuando compró una bolsa de palomitas con la cuarta parte:
[tex] P = \frac{1}{4}x [/tex] (2)
Entonces al sobrarle 5 euros y relacionando las ecuaciones (1) y (2) con el monto inicial:
[tex] x - C - P = 5 [/tex]
[tex] x - \frac{1}{3}x - \frac{1}{4}x = 5 [/tex]
[tex] x = 12 [/tex]
Por lo tanto, Héctor salió de su casa con 12 euros.

Answer:
1) 18 quarters and 30 nickels2) 8 quarters and 12 nickelsStep-by-step explanation:
1) Let quarters be x and nickels be y.
Equations based on given, 48 coins, total of $6 = 600c:
x + y = 4825x + 5y = 600Substitute y in the second equation, y = 48 - x
25x + 5(48 - x) = 60025x + 240 - 5x = 60020x = 360x = 18Then value of y is:
y = 48 - 18 = 302) Similarly to problem 1.
x + y = 2025x + 5y = 260Substitution: y= 20 - x
25x + 5(20 - x) = 26025x + 100 - 5x = 26020x = 160x = 8Then finding y:
y = 20 - 8 = 1216.0 grams of food contain 130 calories. How many grams of food would you need in order to consume 2150 calories?
Answer:
you can set up a proportion
16.0/130 = x/2150
by cross multiplying you get
130x = 34400
divide by 130 and get
x-264.62

What is y + 5 = 7(x– 8) written in standard form?
Choose 1 answer:
A) x-7y=-61 B)-7x+y=-61 C) x+7y=-61
D) 7x + y = -61
Answer:
B)-7x+y=61
Step-by-step explanation:
y + 5 = 7(x– 8)
y + 5 =(7xX)(7x-8)
y + 5 =(7x)(-56)
y – 5 =(7x)(-56+-5)
y=7x-7x-61/
-7x+y=-61

find the composition of transformations that map ABCD to EHGF
Answer:
(x - 1, y + 1 )
Step-by-step explanation:
Consider the reflection in the y- axis
A point (x, y ) → (- x, y )
Consider the reflection of point A
A(- 5, 2 ) → A'(5, 2 )
Now A → E after the transformations
E = (4, 3 ), thus
A'(5, 2 ) → E(4, 3 )
(x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )
The translation rule is (x, y ) → (x - 1, y + 1 ).
What is Translation?In mathematics, translation is a transformation that moves every point of a figure or a graph the same distance and in the same direction. The object being translated retains its size and shape, but its position changes.
Consider the reflection in the y- axis
A point (x, y ) → (- x, y )
Consider the reflection of point A
A(- 5, 2 ) → A'(5, 2 )
Now A → E after the transformations
E = (4, 3 ), then
A'(5, 2 ) → E(4, 3 )
Thus, the translation rule is (x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )

Given the function
f(x)=-1/2(1-x)^2,
find f(-5).
Answer:
f(x)= -1/2(1-x)^2
replacing x with -5 since -5 was given as the function
f(-5)=-1/2(1-5)^2
according to bodmas we solve what is in the bracket first
f(-5)=-1/2(-4)^2
f(-5)=-1/2(16)
-1/2*16/1
