Answer:
Each cupcake cost $2.50 and each brownie cost $2.00
Step-by-step explanation:
Let x represent the price of each cupcake and let y represent the price of each brownie.
Lily and Maddie bought one cupcake and one brownie for $4.50. Hence the equation is:
x + y = 4.50 (1)
Also Jessica purchased 3 cupcakes and one brownie for $9.50. Hence the equation is given by:
3x + y = 9.50 (2)
To find the price of each cupcake and brownie, we solve equation 1 and 2 simultaneously. To find x, subtract equation 1 from equation 2:
2x = 5
x = $2.50
Put x = $2.50 in equation (1):
2.50 + y = 4.50
y = $2.00
Therefore each cupcake cost $2.50 and each brownie cost $2.00
Answer:
The relationship is Y=2.5X
Step-by-step explanation:
From the sentence
X= 2 and Y= 5
Hence (X/Y) = 2/5
Hence Y= 5X/2 = 2.5X

Answer:
length=92yd
width=49yd
Step by step:
2l+2w=282
l=2w-6
Plug in l
2(2w-6)+2w=282
4w-12+2w=282
6w-12=282
6w=282+12
w=294/6
w=49
Then plug in w
2l+2(49)=282
2l+98=282
2l= 184
l=92
