Answer:
Cost of pop = $2
Cost of snacks = $3
Step-by-step explanation:
Let
Cost of pop = x
Cost of snacks = y
Hauler
x + 4y = 14
Good
2x + 2y = 10
x + 4y = 14 (1)
2x + 2y = 10 (2)
Using elimination method
Multiply (1) by (2)
2x + 8y = 28 (3)
2x + 2y = 10 (2)
Subtract (2) from (3) to eliminate x
8y - 2y = 28 - 10
6y = 18
y = 18/6
y = $3
Substitute y = 3 into (1)
x + 4y = 14 (1)
x + 4(3) = 14
x + 12 = 14
x = 14 - 12
x = $2
Cost of pop = $2
Cost of snacks = $3
Sum means add
x and y are the numbers
sum i 44
x+y=44
smaller s 20 les than larger
x=20+y
or
y=20+x
doesn't matter, just pick one
x=20+y
substue 20+y for x since they are equal
x+y=44
(20+y)+y=44
20+y+y=44
20+2y=44
subtract 20 from both sides
2y=24
divide by 2
y=12
subsitue
x=20+y
x=20+12
x=32
the numbers are 12 and 32

Option 1.
sin(2x) = 2sin(x)cos(x)
cos(2x) = 1 - 2sin(x)^2
