Directions: Solve for x. 1. 3/8x + 6 = 3/4x - 12

Julli [10]

Answer:

The required value for $x = \frac{144}{5} = 28.8$

Step-by-step explanation:

Here,the given expression is:

$\frac{3}{8} x + 6 = \frac{3}{4} x -12$

Now, solving for the value of x:

$\frac{3}{8}x - \frac{3}{4}x = -12 - 6$

or, $\frac{3x - 6x}{8} = -18$

or, $\frac{5x}{8} = 18$

or, $x = \frac{8}{5} \times 18 = 28.8$

Hence, the required value for $x = \frac{144}{5} = 28.8$

Given ƒ(x) = 2x2 − 3x + 7, find ƒ(2.5)

dsp73

Assuming 2x2 is $2x^{2} 
$ you would get 2(2.5)(2.5) - 3(2.5) +7, which is 2(6.25) - 7.5 + 7, 12.5 - 0.5, [12]

Plss help bring up my grade please

vitfil [10]

The easiest way to solve this problem is by calculating the areas of all the sides and adding them together.

Step 1; Calculate the area of the rectangular front & back

A = 2 * (l * w)

= 2 * (25 * 10)

Step 2; Calculate the area of the rectangular sides

A = 2 * (1 * w)

= 2 * (55 * 10)

= 1100 ft^2
