What’s x-2 = 3x-84
Licemer1 [7]

Answer:

x = 41

Step-by-step explanation:

<u>Subtract the lower term in both sides</u>

3x - x = 2x

2x - 84 = -2

<u>Add 84 in both sides</u>

84 -2 = 82

2x = 82

<u>Divide 2 in both sides</u>

2x/2 = x

82/2 = 41

<u>Simplify</u>

x = 41

<u>Answer</u>

x = 41

Which expressions are equivalent to (4⋅a)⋅2 Drag and drop the equivalent expressions into the box. A. 4 x (a x 2) B. 4x2xax2 C 8
aksik [14]

(4*a)*2

lets give a a number: a = 3 so (4*3)*2  = 12*2 = 24

 lets try the options:

A) 4 *(3*2) = 4*6 = 24 = the same

B) 4*2*3*2 = 8*3*2 = 24*2 = 48 = different

C) 8*3 = 24 = same

D) 4*2+3*2 = 8 +6 = 14 = different

E) 2*(4*3) = 2*12 = 24 = same


 so A, C & E would be the equivalent.

Answer:

  Team 3 Turtle, by 4 minutes

Step-by-step explanation:

The speeds of each of the turtles can be computed from ...

  speed = distance/time

Then for each of the turtles, the training pace is ...

  Team 1 Turtle: (18 ft)/(6 min) = 3 ft/min

  Team 2 Turtle: (12 ft)/(4 min) = 3 ft/min

  Team 3 Turtle: (10 ft)/(2 min) = 5 ft/min

The times required to cover the 30 ft distance at these paces are ...

  time = distance/speed

  3 ft/min ⇒ (30 ft)/(3 ft/min) = 10 min

  5 ft/min ⇒ (30 ft)/(5 ft/min) = 6 min

The 2nd-place finishers will take 10-6=4 minutes longer.

The expected winner is Team 3 Turtle by 4 minutes.
