45 degrease (2x-5) what is the value of x

WARRIOR [948]

To solve this problem, you set up the equation 45+(2x-5)=180

Next, subtract 45 from 180 to get the equation 2x-5=135

After that, add 5 to 135 to get 2x=140

Diviode 140 by 2 to get X=70

4. The dimensions of a triangular pyramid are shown below. The height of

lyudmila [28]

Answer:

<h2>The volume of the pyramid is 5 cubic inches.</h2>

Step-by-step explanation:

Assuming that the triangle base dimensions are 1 inche and 5 inches, and the height of the pyramid is 6 inches, the volume would be

$V=\frac{1}{3}Bh$

Where $B$ is the area of the base (triangle) and $h$ is the height.

$B=\frac{1}{2}bh =\frac{1}{2}(1)(5)=2.5 \ in^{2}$

Then,

$V=\frac{1}{3}(2.5)(6)=5 \ in^{3}$

Therefore, the volume of the pyramid is 5 cubic inches.
