Answer:

15x+20y

Step-by-step explanation:

first you would add 10x and 5x to get 15x

then you will have 20y on its own

after that just put in numerical order whith "x" first before "y"

Answer:

15x + 20y

Step-by-step explanation:

First, we need to combine like terms,

10x + 20y + 5x

15x + 20y

Since x and y are different variables, we cannot combine them, meaning that the answer is,

15x + 20y

Force of 55 pounds. How much work is done in moving the cart 30 feet if the cart's handle makes an angle of 19° with the ground?
Oksi-84 [34.3K]
<h3>Answer:  approximately 1560.1 foot-pounds</h3>

Explanation:

Refer to the diagram below. The angle theta is the angle of elevation formed between the horizontal line and the diagonal force being applied (the pulling force). Let x be the horizontal component pulling force, which is the horizontal portion of the right triangle. We know the hypotenuse of this triangle is 55 pounds as it is the force applied.

Use the cosine ratio to help solve for x. Make sure your calculator is in degree mode.

cos(angle) = adjacent/hypotenuse

cos(19) = x/55

x/55 = cos(19)

x = 55*cos(19)

x = 52.0035216579624 which is approximate

Roughly 52.0035216579624 pounds of force is being applied in a pure horizontal direction. The cart moves 30 feet, so,

work = (force)*(displacement)

work = (52.0035216579624)*(30)

work = 1560.10564973888

work = 1560.1 foot-pounds

A foot-pound is a unit of work, similar to how a joule is as well (though a joule measures in kilograms and meters)

What is -10x+9x+14-1=4
ch4aika [34]

-10x+9x+14-1=4

then you add similar elements which gives you -x+14-1=4

next you subtract the numbers 14-1=13

then subtract 13 from each side -x+13-13=4-13

then you simplify -x = -9

divide both sides my negative 1 -x/-1 = -9/-1

and then you get the answer: x=9
