3/5 (10x + 15) = +30 help me please
sergeinik [125]

Answer:

x = 3.5

Step-by-step explanation:

\frac{3}{5} (10x + 15) = 30

10x + 15  = 30 * \frac{5}{3}  

10x + 15   = 10 * 5

10x + 15   = 50           {Subtract 15 form both sides}

         10x = 50 -15

        10x = 35         {Divide both sides bt 10}

    10x/10 = 35/10  

          x = 3.5

An equation of the line that contains the origin and the point (1,2) is
Semmy [17]
(0,0)(1,2)......(0,0) is the origin
slope = (2-0) / (1-0) = 2/1 or just 2

y = mx + b
slope(m) = 2
(1,2)...x = 1 and y = 2
now we sub, we r looking for b, the y intercept
2 = 2(1) + b
2 = 2 + b
2 - 2 = b
0 = b

ur equation is : y = 2x + 0...or just y = 2x
