PLEASE! An item costs 410 before tax, and the sales tax is 32.80.
Find the sales tax rate. Write your answer as a percentage.

Answer:

7

Step-by-step explanation:

-x+2+5x=10(x-4)

4x+2=10x-40

2+40=10x-4x

42=6x

42/6=6x/6

7=x

Answer:

x = 7

Step-by-step explanation:

-x + 2 + 5x = 10 (x - 4)

=> 4x + 2 = 10x - 40

=> 4x - 10x = -40 - 2

=> -6x = -42

=> 6x = 42

=> x = 42/6

=> x = 7

Answer:

0.07

Step-by-step explanation:

Answer:

7 x [tex]10^{-2}[/tex]

Step-by-step explanation:

1. Estimate 0.067238149 to the nearest hundredth.

In the decimal 0.067238149, 6 is in the hundredth position. So round decimal to 0.07, since the 7 in the original decimal 0.067238149, which is in the thousandths position, is 5 or more.

2, Express your answer as a single digit times a power of ten.

0.07 becomes 7.

Then, to get the power of ten, in the original decimal 0.067238149, place an imaginary decimal between the 6 and 7. Next, count to the left to find out how many places there are to the original decimal.  There are 2 spaces.

Therefore, the answer is 7 x [tex]10^{-2}[/tex] .

Answer: [tex]7\sqrt{2[/tex]

Step-by-step explanation:

a²+b²=c²

7²+7²=c²

49+49=c²

[tex]\sqrt{98}=\sqrt{c^2}\\\sqrt {49}\sqrt{2} =c\\ 7\sqrt{2} =c[/tex]

Answer:

7[tex]\sqrt{2}[/tex]

Step-by-step explanation:

To find the missing length of a right triangle use the Pythagorean theorem. This theorem is [tex]a^2+b^2=c^2[/tex]. The variables a and b are the legs (shorter sides) and c is the hypotenuse (longest side). In this case, the hypotenuse is the missing side. So, add and square 7. This looks like [tex]7^2+7^2=x^2[/tex]. So, [tex]98=x^2[/tex]. Finally, square root 98 to get the final answer, [tex]\sqrt{98}[/tex]. This can be simplified to [tex]7\sqrt{2}[/tex].

Additionally, this is a special right triangle because the legs are of equal length. If the legs are equal then the hypotenuse with be equal to x[tex]\sqrt{2}[/tex], where x is the length of the legs. So this problem can also be solved using this method.

Answer:

5x²-3x-14

Step-by-step explanation:

(3x-6)(2x+3)+(2-x)(2+x) = (6x²+9x-12x-18)+(2²-x²)

                                     = 6x²+9x-12x-18+4-x²

                                     = 6x²-x²+9x-12x-18+4

                                     = 5x²-3x-14

Answer:

(x - 2)(5x + 7)

Step-by-step explanation:

(3x - 6)(2x + 3) + (2 - x)(2 + x) ← expand factors using FOIL

= 6x² - 3x - 18 + 4 - x² ← collect like terms

= 5x² - 3x - 14

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × - 14 = - 70 and sum = - 3

The factors are - 10 and + 7

Use these factors to split the x- term

5x² - 10x + 7x - 14 ( factor the first/second and third/fourth terms

= 5x(x - 2) + 7(x - 2) ← factor out (x - 2) from each term

= (x - 2)(5x + 7) ← in factored form

✳︎ ✳︎ ✳︎ ✳︎ ✳︎ ✳︎ Hello There! :)

To determine whether the two expressions are equivalent, we take the second expression and distribute 2:

2(3x+1)

6x+2=2+6x

And now we know the two expressions are equivalent. If you look, you will remember the Commutative Property that states:

a+b=b+a

In this case, a=6x and b=2.

So we know that the two expressions are equivalent.

Hope this helps! :)

The cost of the Crayons will be $4 and the cost of the Pen will be $2.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Krishnan had $10. He had to purchase a box of pastels and a pen. A case of pastels costs two times as much as a pen. He got a $4 change.

Let c be the cost of crayons and p be the cost of a pen. Then the equations are given as,

c = 2p                       ...1

c + p = 10 - 4            ...2

From equations 1 and 2, then we have

2p + p = 10 - 4

3p = 6

p = 2

Then the cost of the crayons will be given as,

c = 2 x 2

c = 4

The cost of the Crayons will be $4 and the cost of the Pen will be $2.

Answer:

Step-by-step explanation:

5(5)-3x7+3 Due to parenthesis you need to multiply 5 to 13-8 (which is 5) first.

25-3x7+3 Now you need to multiply 3 and 7 before anything else

25-21+3 now since its just subtraction and addition you go from left to right

4+3

7

Answer:

7

Step-by-step explanation:

Using order of operations to solve the expression:

Step 1: any terms in parenthesis

(13-8)=5

The expression becomes 5(5)-3*7+3

Step 2: any exponents

There are no exponents so the expression doesn't change.

Step 3: multiplication or division

5(5)=25

3*7=21

The expression becomes 25-21+3

Step 4: addition or subtraction

25-21+3=7
