1. A student lifts a box of books that weighs 200 N. The box is lifted 2.5 m. How much work

Angelina_Jolie [31]

The student does a work of 500 Newton meter on the box.

Step-by-step explanation:

Given,

Weight of box of books = force = 200 N

Distance the box is lifted = 2.5 m

Work done = Force * distance

Work done = $200*2.5$

Work done = 500 Newton-meter

Newton meter is same as Joule.

Work done = 500 Joules

The student does a work of 500 Newton meter on the box.

Twice x, plus 7, is the same as – 10.<br> The answer is N

sergij07 [2.7K]

Answer:

x=-8.5.

Step-by-step explanation:

First, write an equation. Twice x (2x) plus 7 (+7) is the same as (=) negative ten (-10), or 2x+7=-10. To solve, first subtract 7 from both sides to get 2x=-17. Then, divide both sides by 2 (x=-8.5).

10 - d = -34 - 5d show the work

Naddika [18.5K]

Answer:

d = 11

Step-by-step explanation:

10 - d = -34 - 5d

10 (- d + d) = -34 (- 5d + d)

10 = -34 - 4d

10 + 34 = (-34 + 34) - 4d

44 = 4d

44/4 = 4d/4

d = 11
