Answer:
x = -24
Step-by-step explanation:
3(x + 7) = 2x - 3
3 * x = 3x
3 * 7 = 21
3x + 21 = 2x - 3
-21 -21
3x = 2x -24
-2x -2x
x = -24

Given
Diameter of round pizza
Side of square pizza
Area of circle
The area of a square is
The area of square pizza is
Clearly, the area of square pizza is more and the difference in their area is
The standard form of a quadratic equation is
,
where , , and are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.
In this case, the given equation is
Since is on the right side of the equation, we subtract that from both sides. The resulting equation is
Looking at the standard form equation , we can see that
Answer:
12.30
Step-by-step explanation:
1.30x4=5.20
54.40-5.20=49.20
49.20/4= 12.30
Assume that the budget is n.
Now we are given that 120% of the budget is equal to $60.
This means that:
60 = 1.2n
Solve the equation for n to know the budget:
60 = 1.2n
n = 60 / 1.2 = 50
Based on the above calculations, Jada's budget is 50$
