Solve the linear equation. 8x+32=2(25x−15)−11x8x+32=2(25x−15)−11x
Bogdan [553]
It seems like you put the same equation up there twice, but no worries! :)

8x + 32 = 2(25x - 15) - 11x

Simplify.

8x + 32 = 50x - 30 - 11x

Add like terms.

8x + 32 = (50x - 11x) - 30

Simplify.

8x + 32 = 39x - 30

Now we must subtract 32 from both sides.

8x = 39x - 30 - 32

Then, subtract 39x from both sides.

8x - 39x = -30 - 32

Simplify.

-31x = -62

Finally, divide both sides by -31.

-31x ÷ -31 = -62 ÷ -31

Simplify.

x = 2

= (2000*7)-12780-26=1194

12)  Profit = Selling price - purchase price - other expenses

=52.25(550)-28275-32=430.50=430(after rounding off)

13) Annual interest on bond

=INterest rate on face value of bond for 1 year

=2000(6%)=120

14)Cost of bond

= quoted value (rate)

=3500(80.5)

=2817.50

= quoted value (rate)

=4250(83.5)

=3548.75

Can you please help me? Thanks!!!!
ss7ja [257]
The answer is 25 degrees.

This is how you solve the equation, first you must know that the straight like ABC=180, DBC is 130, so the remaining amount is 50 degrees, BE is a bisector of ABD which means it splits ABD right down the middle. So ABE+EBD=50 degrees, 25+25=50 since both sides MUST be equal in order for BE to be a bisector of ABD.
