Answer:
y= (-3x+8)/4
x = (-4 +8)/3
Step-by-step explanation:
3x + 4y = 8
-3x -3x
4y = -3x +8 divide ALL by 4
y= (-3x+8)/4
3x + 4y = 8
-4y -4y
3x = -4 +8 divide ALL by 3
x = (-4 +8)/3

Step-by-step explanation:
Candy Bar- $.99
Drink- $1.50
Chips- $1.00
Hair Gel- $3.00
Gum- $.50
Can- $.75
Salsa- $2.00
Eggs- $2.00
Milk-$1.50
Toothpaste- $1.00
The area of each of the 4 triangles is
... A = (1/2)bh = (1/2)(4)(3) = 6
The area of the square base (in the center of the net diagram) is
... A = s² = 4² = 16
Then the total area is 4×6 + 16 = 40 square units.
The interest is $77.60 i think
In the equation for surface area the radius is squared ( r^2)
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.
