3x/4 = 7 - x/3    -> multiply both sides by 3

9x/4 = 21 - x     -> multiply both sides by 4
9x = 84 - 4x
13x = 84
x = 84/13

I need help with this problem
Anit [1.1K]

Answer:

show how you know  .. :D  good rhyme  

Step-by-step explanation:

park = 4" x 6"    ( inches)  small park

but one inch = 30 miles  ooh big park

4*30 X 6*30

120 X 180  miles... like a big game range?  :?  very big

since we only have 6 square inches to fit the map into... then.. what size of map would fit?    what size equals 6 inches?    2 x 3 ?  hmm yes that's 6

soooo  shrink the 4" x 6" to  2"x 3" so the scale needs to double or

1 inch = 60 miles

2"*60  x 3"*60 = 120 x 180 miles.. looks good   try that :)

Cuál es el resultado de |-15| x (-5)​
notka56 [123]

Answer:

\frac{15}{x^5}

Step-by-step explanation:

\left|-15\right|x^{-5}

Step 1: Apply exponent rule: \:a^{-b}=\frac{1}{a^b}

=\left|-15\right|\frac{1}{x^5}

Step 2: Multiply fractions: a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}

=\frac{1\cdot \left|-15\right|}{x^5}

Step 3: Simplify

=\frac{15}{x^5}

The result is =\frac{15}{x^5}

<u>Spanish/Espanól</u>

Respuesta:

\frac{15}{x^5}

Explicación paso a paso:

\left|-15\right|x^{-5}

Paso 1: aplique la regla del exponente: \:a^{-b}=\frac{1}{a^b}

=\left|-15\right|\frac{1}{x^5}

Paso 2: multiplica fracciones: a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}

=\frac{1\cdot \left|-15\right|}{x^5}

Paso 3: simplifica

=\frac{15}{x^5}

El resultado es =\frac{15}{x^5}

Given: measure of arc ED = 50° m∠EDK = 80° Find: ∠DSK
svetoff [14.1K]

Answer:

75°

Step-by-step explanation:

∠ESK is the supplement of ∠EDK, so is 100°. ∠ESD = 1/2·arc ED, so is 25°. Since ...

∠ESK = ∠ESD + ∠DSK

you have ...

100° = 25° + ∠DSK . . . . fill in known values

75° = ∠DSK . . . . . . . . . . subtract 25°

_____

Regarding opposite angles of an inscribed quadrilateral

Chord EK divides the 360° circle into two arc: major arc EDK and minor arc ESK. The sum of those arcs is 360°. Each of the inscribed angles that intercepts those arcs has half the measure of the arc. That is, ∠ESK intercepts arc EDK, so has half its measure. Likewise, ∠EDK intercepts arc ESK, so has half its measure. The sum of those opposite angles will be the sum of half the measures of the arcs, so half the sum of the arcs, or 1/2·360° = 180°.

This is why we can say ∠ESK is the supplement of ∠EDK.
