[|] Answer [|]

$\boxed{5 \ \frac{5}{21}}$

[|] Explanation [|]

$-1 \ \frac{3}{7}$ * $-3 \frac{2}{3}$

-----------

Convert Fractions To Mixed Numbers:

$-1 \ \frac{3}{7}$ = $\frac{-10}{7}$

$-3 \ \frac{2}{3}$ = $\frac{-11}{3}$

Multiply Across:

$\frac{-10 \ * \ -11}{7 * 3}$

= $\frac{110}{21}$

Simplify:

= $5 \ \frac{5}{21}$

$\boxed{[|] \ Eclipsed \ [|]}$

Solve algebraically for x and explain each step( using mathematical vocbuary) for the following: 2(x+5)+ 3x = 30

Lelu [443]

First do distributive property
2x + 10 + 3x = 30
Now combine like terms
5x + 10 = 30
Subtract 10 from both sides
5x = 20
Divide both sides by 5
x = 4

A forestal station receives the locations of two fires, one of them in a forest located 11 Km heading N69°W from the station. Th

loris [4]

Answer:

30.7 km

Step-by-step explanation:

The distance between the two fires can be found using the Law of Cosines. For ΔABC in which sides 'a' and 'b' are given, along with angle C, the third side is ...

c = √(a² +b² -2ab·cos(C))

The angle measured between the two fires is ...

180° -(69° -35°) = 146°

and the distance is ...

c = √(11² +21² -2(11)(21)cos(146°)) ≈ √945.015

c ≈ 30.74

The straight-line distance between the two fires is about 30.7 km.
