a force of 2 pounds is needed to stretch a spring 8 inches.what force is required to stretch the spring 16 inches
Korvikt [17]

Answer:

Four (4) pounds

Step-by-step explanation:

Because we required two (2) pounds to stretch the spring eight (8) inches, we need double the force to stretch it sixteen (16) inches. Sixteen is just double the original amount, meaning we need four (4) pounds to stretch the spring sixteen inches.

Hope this helps!

What is the solution of the following equation? 2x-5+3x=35
harina [27]

<em>2x - 5 + 3x = 35 </em>

<em>simplify </em>

<em>5x - 5 = 35 </em>

<em>add 5 to both sides </em>

<em>5x - 5 + 5 = 35 + 5 </em>

<em>simplify </em>

<em>5x = 40 </em>

<em>divide both sides by 5 </em>

<em>5x/5 = 40/5 </em>

<em>simplify </em>

<em>x = 8 </em>

<em> </em>

Three more than twice a number is less than negative thirteen. Solve the inequality for the unknown number.
Goshia [24]

Answer:

Step-by-step explanation:

The number = x

Three more than the number = x + 3

twice the number = 2x

which means:

           

          2x + 3 < -13

          2x + 3 -3 < -13 -3                 (subtract 3 from both sides)

          2x < -16

          2x/2 < -16/2                       (divide 2 from both sides)

          x < -8
