Choose the equation that is equivalent to this statement: 4 is 80% of x Math item stem image CLEAR CHECK 4x=0.8 4=0.8x 4⋅0.8=x x4=80100

4=0.8x

Step-by-step explanation:

4 = 80% of x

4 = 80/100 × x

4 = 0.8x

4 = 0.8x

Step-by-step explanation:

We need to translate these into mathematical equations:

- "4 is"; "is" always means "=", so we have "4 = ..."

- "80%" is just 80/100 because remember that % means "out of 100"

- "of x"; "of" always means "×", so we use multiplication: "* x"

Put this altogether:

4 = (80/100) * x

80/100 = 8/10 = 0.8

4 = 0.8x

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

connie < felicia < stew

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
