Answer:
24.75 = 3*4.50 + x*4.50
x= 2.5 pounds of Granny Smith apples
Step-by-step explanation:
Gala apples = 3 lbs
Granny apples = x lbs
They cost 4.50 a pound
Total cost = 24.75
Total cost = gala apples * cost per pound + granny apples * cost per pound
Substitute in what we know
24.75 = 3*4.50 + x*4.50
24.75 = 13.50 + 4.5x
Subtract 13.50 from each side
24.75-13.50 = 13.50-13.50 + 4.5x
11.25 = 4.5x
Divide by 4.50 on each side
11.25/4.5 = 4.5x/4.5
2.5 =x
Answer:
The solution is: (x, y) = (9, -7)
Step-by-step explanation:
Step 1: Solve one of the equations for either x = or y = . We will solve second equation for y.
x+y=3
y=3-x
Step 2: Substitute the solution from step 1 into the second equation.
3x+4(3-x)=5
Step 3: Solve this new equation.
3x+4(3-x)=5
3x+12-4x=3
-x+12=3
-x=3-12
x=9
Step 4: Solve for the second variable
y=3-x
y=3-9
y=-7
The solution is: (x, y) = (9, -7)

Answer:
A = 201.06 units²
A = 78.54 units²
Step-by-step explanation:
Formula for area of a circle = πr²
✔️Area of the first circle:
r = ½(d) = ½(16)
r = 8
Area = π*8² = π*64
Area = 201.06 units²
✔️Area of the second circle:
r = 5
Area = π*5²
= π*25
Area = 78.54 units²
