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
Let's start...
a recipe say that we have to use 1.75 cups of flour, then 2.5 recipe we have to use
cups of flour, it's iqual 4.375 cup of flour.
The three is in the tenths place so the numerator is 3 and the denominater is 10 so the equivalent fraction would be 3/10
Answer:
a) 77 b)B
Step-by-step explanation:
letterF is the same as 77 meaning that X will be the same as letterF cause the are vertically opposite angles.
I just did the question on math watch.
c.
Higher education can be expensive, and most students who seek degrees must accept some burden of debt.
