6 × 9 ÷ 18 + 100 - 11 + 4

Use the order of operations to simplify:

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

6 × 9 ÷ 18 + 100 - 11 + 4

There are no parentheses or exponents, so multiplication comes first. Multiply 6 and 9.

54 ÷ 18 + 100 - 11 + 4

Next is division. Divide 54 by 18.

3 + 100 - 11 + 4

Finally, add and subtract from left to right.

103 - 11 + 4

92 + 4

Translate to a system of equations:

omeli [17]

Answer:

m + n = 15

m - 3 = n

The numbers are 9 and 6

Step-by-step explanation:

From the question,

The sum of two numbers is fifteen; the first number is m and the second number is n. To translate to a system of equations, we can write that

m + n = 15 ..... (1)

Also, from the question,

One number is three less than the other,

Also, to translate to a system of equations, we can write that

m - 3 = n ...... (2)

If desired, we can determine m and n

From equation (1)

m + n = 15

Then,

m = 15 - n ...... (3)

Put the value of m in equation (3) into equation (2)

m - 3 = n

Then

15 - n - 3 = n

15 - 3 = n + n

12 = 2n

n = 12/2

∴ n = 6

For m, put the value of n into equation 3

m = 15 - n

m = 15 - 6

m = 9

∴ m = 9 and n = 6

Hence, the numbers are 9 and 6

(5x^5) - (80x^3)<br> factoring

elena55 [62]

Answer:

Factoring the term $(5x^5) - (80x^3)$ we get $\mathbf{5x^3(x-4)(x+4)}$

Step-by-step explanation:

We need to factor the term $(5x^5) - (80x^3)$

First we can see that $5x^3$ is common in both terms

So, taking $5x^3$ common:

$(5x^5) - (80x^3)\\=5x^3(x^2-16)$

We can write $x^2-16$ as $(x)^2-(4)^2$

$=5x^3((x)^2-(4)^2)$

Now we can solve $(x)^2-(4)^2$ using the formula: $a^2-b^2=(a+b)(a-b)$

We can write:

$=5x^3((x)^2-(4)^2)\\=5x^3(x-4)(x+4)$

So, factoring the term $(5x^5) - (80x^3)$ we get $\mathbf{5x^3(x-4)(x+4)}$

Compute<br><br> 8*4-4 divided by 2 +1

iragen [17]

Solution of 8 x 4 - 4 divided by 2 +1 is 9.33

<h3><u>Solution:</u></h3>

Given that,

8 x 4 - 4 divided by 2 +1

We have to compute the above equation

Let us write the given sentence mathematically:

$\rightarrow \frac{8 \times 4-4}{2 + 1}$

Let us BODMAS rule to solve the above expression

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.

So let us first perform multiplication of 8 and 4 in numerator

$\rightarrow \frac{32 - 4}{2 + 1}$

Now we can perform addition of 2 and 1 in denominator

$\rightarrow \frac{32-4}{3}$

Now we can perform subtraction of 4 from 32 in numerator

$\rightarrow \frac{28}{3}$

Now perform division of 28 by 3

$\rightarrow \frac{28}{3} = 9.33$

Thus solution of 8 x 4 - 4 divided by 2 +1 is 9.33
