3 0

Answer:

k= -0.2

Step-by-step explanation:

3+2(5k-3)=7 (original)

3+10k-6=7 (distribute 2 in (5k-3))

9+10k=7 (combine like terms 3+-6)

10k=-2 (subtract 9 on both sides to isolate k)

k=-0.2 (divide 10 on both sides to get you're answer/isolate k)

aleksklad [387]

Answer:

1/3

Step-by-step explanation:

when you change the mixed numbers to improper fractions, you get 4/5 * 10/9 ÷ 8/3. you can flip the 8/3 to 3/8 and change the division sign to multiplication, because dividing by a fraction is the same as multiplying by its reciprocal. you can cancel some things and ultimately you get 1/3
