Solve -1/3w -3/5 = 1/5w
Dmitrij [34]

Answer:

w= -9/8

Step-by-step explanation:

-1/3w -3/5 = 1/5w

+1/3w            +1/3 w

-3/5=1/5w+1/3w

Make common denominators to combine like terms of the right

-3/5=1/5w+1/3w

         *3       *5

-3/5=3/15w+5/15w

-3/5=8/15w

multiply both sides by the reciprocal of 8/15 which is 15/8

-3/5*15/8=8/15w*15/8

\frac{-3}{5}*\frac{15}{8} ----> cross reduce 5 in the denominator becomes 1 and 15 in the numerator becomes 3

\frac{-3}{1}*\frac{3}{8} -----> now multiply across

w= -9/8

Given that A=27, B=43 and c=17, solve triangle ABC to the nearest hundredth
katrin2010 [14]
When we are given 3 sides, we try to solve the angles first by using the
law of cosines
cos (A) = [b^2 + c^2 - a^2] / (2 * b * c)
cos (A) = [43^2 + 17^2 -27^2] / (2 * 43 * 17)
cos (A) = [1,849 + 289 -729] / <span> <span> <span> 1,462
</span></span></span>cos (A) = 1,409 / 1,462
cos (A) = <span> <span> <span> 0.96374829001368
Angle A = 15.475

Now that we have one angle, we next can use the
Law of Sines
sin(B) / side b = sin(A) / side a
sin(B) = sin(A) * sideb / sidea
</span></span></span><span>sin(B) = sin(15.475) * 43 / 27
</span><span>sin(B) = 0.26682 * 43 / 27
sin (B) = </span><span>0.424935555555</span>
Angle B = 25.147 Degrees
Remember the arc sine (<span>0.424935555555) also equals </span> <span> <span> <span> 154.85

</span></span></span>Finally, calculating the third angle is quite easy
Angle C =  180 - Angle (A) - Angle(B)
Angle C =  180 - 15.475 - 154.85
Angle C =  9.675

A company has 50 employees all working in the same building.
balandron [24]
Yes it did because 90% of fifty is 45 (50 divided by 10 x 5) and the graph shows that 46 employees left the building within a minute

I don’t understand this at all
xz_007 [3.2K]

Answer:

x=8

Step-by-step explanation:

You would set them equal to each other to get 9x-13=6x+11.

You would them move 6x over so -6x on both sides. This would then get you 3x-13=11.

Then move the -13 over so add 13 to both sides to get 3x=24

Then get x by itself so divide by 3 to get x=24/3.

Then that simplified is 8
