What is the first step to solve the equation 16x-21 = 52?

Makovka662 [10]

Answer:

2) Add 21 to both sides

Step-by-step explanation:

When solving $16x-21=52$ for $x$ , our goal to isolate $x$ such that we have $x$ set equal to something.

Therefore, we want to start by adding 21 to both sides. This leaves us with $16x=73$ and we are one step closer to isolating $x$ .

Let k be the scale factor relating two similar prisms $P_{1}$ and $P_{2}$ , such that for corresponding parts of prisms $P_{1}$ and $P_{2}$ (for heights, in particular) we have $k= \frac{height\ of \ P_{1} }{height \ of\ P_{2} }$ . In our case $k= \frac{4}{10} = \frac{2}{5}$ .
For surfaces area we have $\frac{Surface \ area \ of \ P_{1} }{Surface \ area \ of \ P_{2}} = k^{2} =( \frac{2}{5} )^{2}= \frac{4}{25}$ .
So, the right answer is 4:25 (choice B)
