or

2585/417 lbs.

as a fraction

Step-by-step explanation:

8.34x+48.30=90

        -48.30    -48.30

8.34x=51.70

Yoko bought 4 pounds of coffee

Step-by-step explanation:

90.00 - 8.34 = 81.66

81.66 - 48.30

33.36 divided by 8.34

4

so Yoko bought 4 pounds of coffee

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
