Answer:

x = 6

Step-by-step explanation:

Given

Let y represent the number of meatballs in total and x represents the number of plates.

y = 30

Rate = 5 per plate

Required

Determine the value of x

To solve for x, we make use of the following expression.

y = Rate * x

Substitute values for y and Rate

30 = 5 * x

30 = 5 x

Divide through by 5

30/5 = 5 x/5

6 = x

x = 6

<em>Hence, number of plates is 6</em>

Given the exponential equation 3x = 243, what is the logarithmic form of the equation in base 10?
weeeeeb [17]
The answer is x= \frac{log_{10} (243 )}{log_{10} (3 )}

3^{x} =243
Logarithm both sides of the equation:
log_{10} (3^{x} ) = log_{10} (243 )
Since: log (a^{b}) = b*log(a), then: log_{10} (3^{x} ) =x*log_{10} (3 )
Back to our equation:
log_{10} (3^{x} ) = log_{10} (243 ) \\ &#10;x*log_{10} (3 ) = log_{10} (243 ) \\ &#10;x= \frac{log_{10} (243 )}{log_{10} (3 )}

The Area of a rectangle is 216 square inches. if the perimeter is 60 inches find the lenght and width of the rectangle
Yuki888 [10]
Xy = 216
x = 216/y
2x + 2y = 60
2(216/y) + 2y = 60
432 + 2y^2 = 60y
2y^2 - 60y + 432 = 0
y = 18 , y = 12

if y = 12
x = 216/12
x = 18

length = 18
width = 12
