Answer:

A = (vf - vi) / t <== call this the "given equation "=====================================

For t :Multiply each side of the given equation by 't' : A t = (vf - vi)Divide each side by 'A' : t = (vf - vi) / A=====================================

For vi :Multiply each side of the given equation by 't' : A t = (vf - vi)Subtract ' vf ' from each side: A t - vf = -viMultiply each side by -1 : vf - A t = vi=====================================

For vf :Multiply each side of the given equation by 't' : A t = (vf - vi)Add ' vi ' to each side: A t + vi = vf

Hope it's correct :)

Are the two expressions in the equation 2b + 5 + 1b = 3b + 5 equal or equivalent? How do you know

vodka [1.7K]

Given:

The expression is

$2b+5+1b=3b+5$

To find:

Whether the two expression in the equation are equal or equivalent.

Solution:

If two expression are exactly the same, then they are equal and if the two expressions are different but the after simplification both are same, then they are called equivalent expressions.

We have,

$2b+5+1b=3b+5$

Taking LHS, we get

$LHS=2b+5+1b$

On combining liker terms, we get

$LHS=(2b+1b)+5$

$LHS=3b+5$

$LHS=RHS$

In the given equation both expression are different but after simplification LHS = RHS, therefore the expression are equivalent not equal.

A realtor sold a home for $341,100 The commission was 4% of the sale price; however, the realtor receives only 60% of the com

Pepsi [2]

Answer:

The relator recived $8,186.4

Step-by-step explanation:

What you have to do is find the 60% of the commission. Commission is 4% of $341,100 (100%)

First do a cross multiplication to find 4% of $341,100

100% ___ $341,100

4%______x:

$x=(4*341,100)/100=13,644$

So, the 4% of $341,100 is $13,466

Now you have to find the 60% of $13,466

100% ___ $13,466

60%______x:

$x=(60*13,466)/100=8,186.4$

The answer is: $8,186.4
