How to solve -66.17738=6.618(4.3x+1.1)-7.1(x-6.8) have not done algebra in 30 years and cannot help my son with this problem
fenix001 [56]

Let's solve your equation step-by-step.

−66.17738=6.618(4.3x+1.1)−7.1(x−6.8)

<em>Step 1: Simplify both sides of the equation. </em>

−66.17738=6.618(4.3x+1.1)−7.1(x−6.8)

−66.17738=(6.618)(4.3x)+(6.618)(1.1)+(−7.1)(x)+(−7.1)(−6.8)(Distribute)

−66.17738=28.4574x+7.2798+−7.1x+48.28

−66.17738=(28.4574x+−7.1x)+(7.2798+48.28)(Combine Like Terms)

−66.17738=21.3574x+55.5598

−66.17738=21.3574x+55.5598

<em>Step 2: Flip the equation. </em>

21.3574x+55.5598=−66.17738

<em>Step 3: Subtract 55.5598 from both sides</em>.

21.3574x+55.5598−55.5598=−66.17738−55.5598

21.3574x=−121.73718

<em>Step 4: Divide both sides by 21.3574. </em>

21.3574x

21.3574

=

−121.73718

21.3574

<u>x=−5.7</u>

If X = 4 units, Y = 3 units, and Z = 6 units, then what is the surface area of the right triangular pyramid shown above?
zepelin [54]

Answer:

C. 42

Step-by-step explanation:

<em>Since the triangle making up the base of the right triangular pyramid is equilateral, the three lateral triangles will have equal areas. To find the surface area of the pyramid, find the area of one of the lateral triangles and multiply it by 3. Then, add that to the area of the triangle that forms the base.</em>

<em>Area of Lateral Triangle = 1/2 · base · height</em>

<em>                                        = 1/2 · X · Z</em>

<em>                                       = 1/2 ·  4 units ·  6 units</em>

<em>                                       = 12 square units</em>

<em>Area of Base Triangle = 1/2 ·  base ·  height</em>

<em>                                     = 1/2 ·  X ·  Y</em>

<em>                                     = 1/2 ·  4 units ·  3 units</em>

<em>                                    = 6 square units</em>

<em>Now, use the method described above to find the surface area of the pyramid.</em>

<em>Surface Area = 3( Area lateral ) + ( Area base )</em>

<em>                      = 3 ( 12 square units ) + ( 6 square units )</em>

<em>                     = 42 square units</em>
