Answer:
The ratio of x:y is 1/2
Step-by-step explanation:
Let
x----> the number of Kg of brand A
y ---> the number of Kg of brand B
we know that
400x+280y=320(x+y)
400x+280y=320x+320y
400x-320x=320y-280y
80x=40y
x/y=40/80
x/y=1/2
9514 1404 393
Answer:
(x, y) = (2, 1)
Step-by-step explanation:
Use the second equation to write an expression for x:
x = 1 +y
Substitute that into the first equation:
(1 +y) +4y = 6
5y = 5 . . . . . . . . subtract 1, collect terms
y = 1 . . . . . . . divide by 5
x = 1 +1 = 2 . . . use the expression for x to find x from y
The solution is (x, y) = (2, 1).
Answer:it could have 3 big slices plus the gatorade would come out to be 18 dollars ps that gatorrade is expensive
Step-by-step explanation:
∠AXY=∠XBC=55°(corresponding angles)
XB=XC⇒ΔXBC is isosceles, so ∠XBC=∠XCB=55°
The sum of all the angles in a triangle is 180°⇒
55°+55°+∠BXC=180°
∠BXC=70°
