You will need the fraction on “z” to have a common denominator before you can add the two equations. In this equation the common denominator is 6. So you do not change the left side of the equation however the right side turns into -2/6. Now you can add the z’s together and you can also add the integers together.



After simplification I believe the final answer is 1/2z + 1.

I would maybe wait for someone else to answer so that you can be sure because there are other ways to solve this.

This section of a concrete skateboard ramp has the shape of a triangular prism. Find the volume of the triangular prism. Find th
NISA [10]

Answer:

The volume of the triangular prism: 59.2 ft^{3}

The value of the concrete used is: 16*4 = $64

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo

My answer:

As we know that, the formula to find out the volume of the triangular prism is:

V = \frac{1}{2} a*b*h when h is the height and a&b are the length of the two square edges. So we have:

  • V = \frac{1}{2}*4*4*7.4 = 59.2 ft^{3}

To find the concrete used in the ramp if the cost of concrete is $ 4.00 per cubic foot, we need to know the area of the ramp, which is:

S = 4*4 = 16 ft^{2}

Hence, the value of the concrete used is: 16*4 = $64

How do you find the area of a triangle
natita [175]
Use the formula:

\frac{b\: \times \:h}{2}

B refers to the base and H refers to the height of the triangle.

As such, multiply both the base and height of the triangle and divide the answer by 2, to find the area of the triangle.
