Iteru [2.4K]

There are 5 boxes, where we have to put given numbers. Addition of 5 odd numbers always gives an odd number result. 30 is an even number. So there is no combination of given numbers which can give you 30 as a result.

2. Solve this equation for x: 0.17k - 0.43 = 0.25k + 0.05

stepan [7]

Answer:

k = 6

Step-by-step explanation:

im guessing you meant solve for k

0.17k - 0.43 = 0.25k + 0.05

-0.17k -0.17k

-0.43 = 0.08k + 0.05

-0.05 -0.05

-0.48 = 0.08k

divide both sides of the equal sign by 0.08

6 = k
