Answer:

I really don't know I just wanna know to

Answer:

x = -7

Step-by-step explanation:

-2x - 10 = 4

-2x = 14 | Add 10 to both sides

x = -7 | Divide both sides by -2

Answer:

3 hours x 8 meters = 24 meters + 28 meters = 52 meters

52 / 3 = 17 and 1/3 hours.

Answer:

c=110+5x

Step-by-step explanation:

The equation that represents the total cost is C = 5x + 110.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The expense of leasing a bowling alley for a party is $110, in addition to $5 an individual for food.

Let 'C' be the total cost and 'x' be the number of friends. Then the equation is written as,

C = 5x + 110

The equation that represents the total cost is C = 5x + 110.

Answer: No,   He will need $22 to add to his money to  buy jacket.

Step-by-step explanation:

Normal price  of jacket =$120,

New price = 40% off  which means 40% Less than the Normal price

 = 40/ 100 x 120

=0.4 x 120 = 48; 120 -48= $72

New Price = $72

Therefore Roberto with $50 to spend does not have enough to buy the jacket

He will need $72- $50 =$22  to add to his money to  buy jacket.

Standard form of given expanded form of a number is 16518.

The expanded form of the number is the splitting of numbers based on the place value, such as ones, tens, hundreds, thousands, ten thousand, and so on. The number that is represented by the sum of each digit multiplied by its place value is called the expanded form of the number.

Given

Expanded form = (5×1,000)+(7×10)+(8×1)+(4×110)+(1×11,000)

We have to convert the expanded form into standard form

= 5000 + 70 + 8 + 440 + 11000

= 16518

Thus, standard form of given number is 16518.

Answer:

16,518

(or  1.6518 x 10⁴)

Step-by-step explanation:

Expanded form:  The digits of a number are split into individual digits based on their place value.  Each digit of a number can be written in  multiple of 1, 10, 100, 1000, etc.

Standard form:  The combination of digits written together as a single number.

The given number is not quite, but almost, written in expanded form:

(5 × 1,000) + (7 × 10) + (8 × 1) + (4 × 110) + (1 × 11,000)

For it to truly be written in expanded form, the (4 × 110) would be written as (4 × 10) + (4 × 100) and the (1 × 11,000) would be written as either (11 × 1,000) or (1 × 10,000) + (1 × 1,000).

If the number should be written in standard form as defined above, carry out the operations in the parentheses, then add them together:

[tex]\large\begin{array}{l c r}8 \times 1 & = & 8\\7 \times 10 & = & 70\\4 \times 110 & = & 440\\5 \times 1000 & = & 5000\\1 \times 11000 & = & 11000\\\cline{3-3}& & 16518\end{array}[/tex]

-----------------------------------------------------------------------------------------------------

However, in math there is another type of Standard Form (also called "Scientific notation") that is written in the form of [tex]a \times 10^n[/tex], where  [tex]1\leq a < 10[/tex]  and  [tex]n[/tex] is any positive or negative whole number.

To convert a number into standard form, move the decimal point to the left or right until there is one digit to the left of the decimal point.

The number of times you have moved the decimal point is the power of 10 ([tex]n[/tex]).

If the decimal point has moved to the left, the power is positive.

If the decimal point has moved to the right, the power is negative.

To convert 16518 into standard form:

Move the decimal point 4 places to the left and multiply by 10 to the power of the number of places the decimal was moved (4):

⇒ 1.6518 x 10⁴

Step-by-step explanation:

By Basic Proportionality Theorem:
