What is the length of the unknown leg

likoan [24]

Answer:

6 mm

Step-by-step explanation:

Use the Pythagorean Theorem to solve for the unknown leg

$a^{2} +b^{2}=c^{2}$

Since we need to solve for a, we will manipulate the equation in terms of b and c → $a=\sqrt{c^{2}-b^{2} }$

Here, b = 7 mm and c = $\sqrt{85}$ mm

Plugging these numbers into our equation gives us $a=\sqrt{(\sqrt{85})^{2} -(7)^{2} }$ → $\sqrt{85-49}$ = $\sqrt{36}$ = 6 mm

Please help me <br>solve 3x+1/2=3/8+x

gavmur [86]

Answer:

x= - $\frac{1}{32}$

Step-by-step explanation:

First move the x on the right side the the left side. Now your equation is

2x+ $\frac{1}{2}$ = $\frac{3}{8}$ Next move 1/2 to the right side. Now your equation is 4x= $\frac{-1}{8}$ . Next divide both sides by 4 to isolate "x." Now your equation is x= - $\frac{1}{32}$

Hope this helped and have a great day.

30% is 3/10. 260 times 3/10 is 780/10, or 78. She read 78 pages. 260 - 78 is 182 pages left.
