The tax rate is 7.5% What is the tax on 110?

Answers

Answer 1

Answer:
The answer is 8.25

110/x=100/7.5
(110/x)*x=(100/7.5)*x -
110=13.333333333333*x -
(13.333333333333) to get x
110/13.333333333333=x
8.25=x
x=8.25

Answer 2

Answer: 110 * .075 = 8.250
8.25 = 8.30
The tax on 110 is 8.30.

Complete the equation to show two equivalent expressions.

g2 – 4g – 21 = (g – )(g + )

Answers

Answer:

$g^2-4g-21=(g-7)(g+3)$

Step-by-step explanation:

To complete the left side of the equation, we need to bring it to the form

$(g-a)(g+b)$

expanding this expression we get:

$g^2+bg-ag-ab$

$g^2+(b-a)g-ab$

Thus we have

$g^2-4g-21=g^2+(b-a)g-ab$

from here we see that for both sides of the equation to be equal, it must be that

$b-a=-4$

$-ab=-21$ .

Getting rid of the negative signs we get:

$a-b=4$

$ab=21$

At this point we can either guess the solution to this system (that's how you usually solve these types of problems) or solve for $a$ and $b$ systematically.

The solutions to this set are $a=7$ and $b=3$ . (you have to guess on this—it's easier)

Therefore, we have

$(g-a)(g+b)=(g-7)(g+3)$

which completes our equation

$\boxed{ g^2-4g-21=(g-7)(g+3)}$

Can you help me solve and describe the steps used to find x for the equation 2(x + 4) – 10 = 12

Answers

for solving 1st degree equations (highest exponent on placeholder is 1) the rules are

1. isolate variable
2. divide by coeficient of variable
3. celebrate because you found the answer

remember you can do anything to an equation as long as you do it to both sides

distributive propoerty
a(b+c)=ab+ac

2(x+4)-10=12
distribute the 2 to (x+4)
2(x+4)=2x+8

now we have
2x+8-10=12
add
2x-2=12
add 2 to both sides
2x+2-2=12+2
2x+0=14
2x=14
divide both sides by 2
2/2x=14/2
1x=7
x=7

Hi there!

To solve, let's rewrite this equation.

$2 (x + 4) - 10 = 12$

Step 1) Simplify both sides of the equation.

$(2) (x) + (2) (4) + - 10 = 12 2x + 8 + - 10 = 12$ (Distribute)

$(2x) + (8 + - 10) = 12$ (Combine Like Terms)

$2x + - 2 = 12 2x - 2 = 12$

Step 2) Add 2 to both sides.

$2x - 2 + 2 = 12 + 2 2x = 14$

Step 3) Divide both sides by 2.

$(2x)/(2) = (14)/(2)$

$x = 7$

Final Answer -

$x = 7$

Hope this helps!

Answer:

2,300

Step-by-step explanation:

When we round to the hundreds place, we make sure the numbers behind the hundreds place are zero. Then we round. Here's the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. In this case we round the 2 in the hundreds place up to three because it is followed by a five.
