Mario invested $475 in $45 and $25 stock shares. The number of $25 shares was 5 less than 3 times the number of $45 shares. How
Anit [1.1K]

\text{Answer : Number of \$45 shares} =120

\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355

Explanation:

Let Number of $45 shares be x

Let number of $ 25 shares be 3x-25

According to question,

x+3x-5=475\\\\4x-5=475\\\\4x=475+5\\\\4x=480\\\\x=\frac{480}{4}\\\\x=120

So,

\text{Number of \$45 shares} =120

\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355

2. Evaluate f(x) = 3x+5/x-1<br> at x = 3
pashok25 [27]

Answer

Let f(x) = ax + b

Then

f(x + 1) = a(x + 1) + b

= ax + a + b

Hence, a = 3, and a + b = 5, b = 2

f(-2) = 3(-2) + 2

= -6 + 2

= - 4

f(2x) = 3(2x ) + 2

= 6x + 2

Thus, you can create a right triangle. Finally, use the Pythagorean Theorem to solve for x, the length of the side of the cube.
