The answer is gonna be x+3/x-2
Answer: 4x + 3 = 39
Step-by-step explanation:
Because you don't know how much each pizza costs, you can write it as x.
You multiply x by 4 to get 4x and add 3 because thats how much the chips cost.
That added up should equal 39 because thats how much he spent.
Given:
Shapes: Trapezoid and Triangle.
Trapezoid: Upper base = 14mm ; lower base = 18mm
Triangle: base = 18mm ; height = 12mm
Total height of the figure is 17 mm
Area of a trapezoid = (upper base + lower base)/2 * height
A = (14mm+18mm)/2 * (17mm-12mm)
A = 32mm/2 * 5mm
A = 16mm * 5mm
A = 80 mm²
Area of a triangle = (height * base) ÷ 2
A = (12mm * 18mm) ÷ 2
A = 216mm² ÷ 2
A = 108 mm²
Total area of the figure = 80 mm² + 108 mm² = 188mm²
Impossible.
The reason is because there is no way you will get a '7' on a die that is marked 1 - 6. There is no 7.
Answer:
x=2.4
Step-by-step explanation:
2(x+1)+6=20-3x
We simplify the equation to the form, which is simple to understand
2(x+1)+6=20-3x
Reorder the terms in parentheses
+(+2x+2)+6=20-3x
Remove unnecessary parentheses
+2x+2+6=+20-3x
We move all terms containing x to the left and all other terms to the right.
+2x+3x=+20-2-6
We simplify left and right side of the equation.
+5x=+12
We divide both sides of the equation by 5 to get x.
x=2.4
