What equation is equivalent to 9x - 3 = 729? 9x - 3 = 981 9x - 3 = 93 3x - 3 = 36 32x - 3 = 36
lilavasa [31]

Answer:

Option 2nd is correct

9^x-3 =9^3

Step-by-step explanation:

Given the equation:

9^x-3 = 729

We can write 729 as

729 = 9 \cdot 9 \cdot 9 = 9^3

then;

9^x-3 =9^3

Therefore, the equation which is equivalent to 9^x-3 = 729 is, 9^x-3 =9^3

Find the value of x so that FED ~ZYZ <br> need help asap
Paul [167]

Answer:

x=7.5

Step-by-step explanation:

To show that the triangles are similar, we simply need to show that all sides are proportionate.

So,  we create a proportion

\frac{FE}{ZY} =\frac{ED}{XY} = \frac{FD}{XZ}

Then we plug in the values

\frac{6}{12} = \frac{7}{14}  = \frac{2x-5}{22}

\frac{6}{12} and \frac{7}{14} can be simplified to \frac{1}{2}, so that is our ratio of similarity

then we know

\frac{1}{2} = \frac{2x-5}{22}

Now solve

1. Cross multiply

2×(2x-5) = 22

2. Distribute

4x-8 = 22

4x=30

x=7.5

There is your answer, x=7.5

Hope this helped.
