Like terms are those terms that are having the same variables, also the variables are of the same order as well. The first step to solving an equation is to rearrange the like terms.

<h3>What are Like terms?</h3>

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

To solve an equation the first step is to rearrange the equation such that like terms are together.

Hence, the first step to solving an equation is to rearrange the like terms.

2 Dylan is part of a volunteer crew constructing houses for low-income families. Dylan is experienced at installing tile floors.
g100num [7]

Answer:

For the tiling Job; it takes the following for installing 100 tiles:

Dylan =2 hours

George = 4 hours

if they work together for the job, for 1 hour,

it would be the following no of tiles to be fixed:

Dylan + George =  total tiles

100/2  +  100/4  = 50 + 25 =  75 tiles

If it takes George 1hr to fix 50 tiles,

For 30 minutes, Dylan will fix 25 tiles

Therefore Total tiles fixed = Dylan(1hr work) + George(1hr work) + Dylan (30mins work)

= 50 tiles + 25 tiles + 25 tiles = 100 tiles

Therefore, it will take approximately 1 hour for them to install 75 tiles in the low-income house for the families or

1.30 hours (1 hr, 30 minutes) to fix 100 tiles for the same low income families.

Find the exact value of the slope of the line which is tangent to the curve given by the equation
Viktor [21]

Answer:

-2

Step-by-step explanation:

x = r cos θ

y = r sin θ

dx/dθ = -r sin θ + r' cos θ

dy/dθ = r cos θ + r' sin θ

dy/dx = (r cos θ + r' sin θ) / (-r sin θ + r' cos θ)

At θ = π/2, cos θ = 0, sin θ = 1, and r = 1.  So the derivative simplifies to:

dy/dx = (r') / (-1)

dy/dx = -r'

dy/dx = -2 sin θ

dy/dx = -2
