An ice skater is skating at a speed of √64/5 miles per second. a) about what speed (to 2 decimal places) is the ice skater skating. b) if teh speed of the skater changes to 4 miles per second, is the skater skating at a speed greater than √64/5 miles per second. explain using a numberline

By 2.4 miles per hour

Step-by-step explanation:

Current Speed is given as

Hence

If the Speed is increased to 4 mph

This speed is greater by

4-1.6=2.4 mile per hour

∞ this is your sign

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
