Answer:

x=-1

Step-by-step explanation:

6x(1/3)-15(1/3)=10x(1/2)-4(1/2)

6/3x-15/3=10/2x-4/2

2x-5=5x-2

-5+2=5x-2x

-3=3x

-3/3=x

-1=x

Urgent please help..
Strike441 [17]

Answer:

b = 7√3

Step-by-step explanation:

This 30°- 60°- 90° triangle has the proportions:

side opposite of the 30° angle = x

side opposite of the 60° angle = x√3

side opposite of the 90° angle = 2x

____________________________

Given the side opposite of the 30° angle which is 7 units long, this can be thought of as x. Knowing the proportions of the other sides, we can find b knowing that this is the side opposite of the 60° angle which is x√3.

Since x = 7, x√3 = 7√3, and therefore

b = 7√3.

Find all real numbers s such that -2(s - 7) &gt; 4s + 8. Give your answer as an interval.
aev [14]
   If    -2 (s - 7) > 4s + 8
then  -2s + 14 > 4s + 8
           14 - 8 > 4s + 2s
                  6 > 6s
         
∴ <span>all real numbers s such that -2(s - 7) > 4s + 8  are   s < 1</span>
