<h3>Answer: 90 cubic meters</h3>

Each triangle has a base of 10 and height of 3.6

area of triangle = 0.5*base*height = 0.5*10*3.6 = 18 square meters

multiply this with the height of the prism (5 meters) to get 18*5 = 90 cubic meters. I'm using the idea that,

volume of prism = (area of base face)*(height of prism)

The notation "m^3" is shorthand for "cubic meters"

We do not use the other dimensions of 9 m and 7 m.

Y is six more than x divided by three <br><br> turn it into an expression (y=mx+b format)

Snowcat [4.5K]

We always start from right side in order of operation in any equation

we can set up equation as

step-1:

x divided by three

we can write as

$=\frac{x}{3}$

step-2:

six more than x divided by three

so, we get

$=\frac{x}{3}+6$

step-3:

y is six more than x divided by three

so, we get

$y=\frac{x}{3}+6$

and this is in y=mx+b form

so, we have

$y=\frac{x}{3}+6$ ...............Answer

Answer:

5 = |-5|

Step-by-step explanation:

Think of it as a number line, like in the picture below. The absolute value is how far a number is from zero (0). If 5 is 5 away from zero, then the opposite of 5 (-5) is also 5 away from zero.

Refer to the picture below for an illustration:
