Answer:
The dryer costs $350
Step-by-step explanation:
<u>Step 1: Make a system of equations</u>
<em>w + d = 652</em>
<em>w = d - 48</em>
<em />
<u>Step 2: Plug in the know w into the first equation</u>
d - 48 + d = 652
2d - 48 + 48 = 652 + 48
2d / 2 = 700 / 2
<em>d = 350</em>

Answer:
i think its c
Step-by-step explanation:
A = 6s²
a) s = 3in, subtitute
A = 6 · 3² = 6 · 9 = 54 (in²)
b) s = 1.5 m, subtitute
A = 6 · 1.5² = 6 · 2.25 = 13.5 (m²)
