Answer:
x=5
Step-by-step explanation:
We simplify the equation to the form, which is simple to understand
3x+5-5=20-5
We move all terms containing x to the left and all other terms to the right.
+3x=+20-5-5+5
We simplify left and right side of the equation.
+3x=+15
We divide both sides of the equation by 3 to get x.
x=5
The answer would be $697.5
Hope this helps!
Well, it is a good and interesting question
Such areas could be calculated in a single shoot and also by dividing the whole shape into other shapes and the total area would be the sum of these areas
I prefer the way of a single shoot ...
The figure represents a trapezoid:
its lower base = 21 units
its upper base = 12 units
the normal height between them = 8 units
NOW
The area of a trapezoid = [(sum of bases' lengths) ÷ 2] * height
= [(12 + 21) ÷ 2] * 8 = 132 sq units
Hope that helps
Answer:
Then, Jane had twice as much money as her sister. How much money did their parents give each of them?

Answer:
x = 3, y = 0
Step-by-step explanation:
2x - 2y = 6
x - y = 3
x = 3 + y
3(3 + y) + 2y = 9
9 + 3y + 2y = 9
5y = 0
y = 0
x = 3 + 0
x = 3
