Answer: The answer is 500,000.

Step-by-step explanation:

100% - 30%  = 70%

          x   =>    100%

350000   =>      70%

x = 350000*100% / 70%

x = 500000

-4x-2y=-12 <br>4x+8y=-24​
sweet [91]

Answer:

x = 6

y = -6

Step-by-step explanation:

By adding both equations :-

=》-4x -2y + 4x + 8y = -12 + (-24)

=》-4x + 4x + 8y - 2y = -12 - 24

=》6y = -36

=》y = -36 ÷ 6

=》y = -6

putting the value of y in equation 2

=》4x + 8y = -24

=》4x + (8 × -6) = -24

=》4x - 48= -24

=》4x = 48 - 24

=》x = 24 / 4

=》x = 6

Can someone plz help I do not know what I am doing
PolarNik [594]

the answer is D-n is greater then or equal to nine.

because the red dot starts on nine and goes up its greater than nine and because its on nine its also going to equal it. I had a problem getting the signs messed up when I learned it but I remember the sign always eats the greater number. I hope this answer could help and I'm sorry if the answer is incorrect.

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. B = 107°, a
Archy [21]

Answer:    105.19 \text{ square cm}      

Step-by-step explanation:

Since, by the SAS formula of finding the area of triangle,

The area of triangle, A = \frac{1}{2}\times s_1\times s_2\times sin\theta

Where, s_1 and  s_2 are adjacent sides and \theta  is the included angle of these sides

Here, s_1=22 s_2=10

And, \theta=107^{\circ}

Thus, the area of the triangle ABC,

A = \frac{1}{2}\times 22\times 10\times sin (107)^{\circ}

A = 110\times 0.95630475596

A = 105.193523156\approx 105.19\text { square cm}

Therefore, Third Option is correct.
