Answer:
The cost of each ice cream cone is $4.50
The cost of each ice cream basket is $3.75
The cost of each donut is $1.50
Step-by-step explanation:
Let
x-----> the cost of the ice cream cone
y----> the cost of the ice cream basket
z---> the cost of the donut
we know that
2x+y=12.75 ------> y=12.75-2x ------> equation A
x+2z=7.50 ------> z=(7.50-x)/2 -----> equation B
x+y+z=9.75 ----> equation C
substitute equation A and equation B in equation C and solve for x
x+(12.75-2x)+((7.50-x)/2)=9.75
Multiply by 2 both sides
2x+25.50-4x+7.50-x=19.50
3x=25.50+7.5-19.50
3x=13.5
x=$4.50
Find the value of y
y=12.75-2(4.50)=$3.75
Find the value of z
z=(7.50-4.50)/2=$1.50
therefore
The cost of each ice cream cone is $4.50
The cost of each ice cream basket is $3.75
The cost of each donut is $1.50

<span>Simplifying
9x + -2y = 19
Solving
9x + -2y = 19
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
9x + -2y + 2y = 19 + 2y
Combine like terms: -2y + 2y = 0
9x + 0 = 19 + 2y
9x = 19 + 2y
Divide each side by '9'.
x = 2.111111111 + 0.2222222222y
Simplifying
x = 2.111111111 + 0.2222222222y</span>
Answer:
(a+2)
Soo you could solve by removing the parenthesis, then combining all like terms. Then subtract.
