Working 6 days, a worker earned 150000 LL a) How much will he earn by working 21 days?

Mila [183]

Answer:

525,000 LL

Step-by-step explanation:

6 x 3 = 18 (days)

150,000 x 3 = 450,000

21 - 18 = 3 so 6 * 2 = 3 ( 150,000 *(divide) 2 = 75,000)

so 450,000 + 75,000 = 525,000

The value of y varies directly with x, and y= -10 when x=40. Identify the value of y when x=-5

scoray [572]

Answer:

y = 1.25

Step-by-step explanation:

Use the direct variation equation y = kx, and solve for k:

y = kx

-10 = k(40)

-0.25 = k

So, the equation is y = -0.25x. Solve for y when x = -5

y = -0.25x

y = -0.25(-5)

y = 1.25

So, y = 1.25 when x = -5
