How do you do this problem X98=98,000

Butoxors [25]

Answer: The value of X is 1000

Step-by-step explanation:

X98 = 98,000 means a variable 'X' multiplied by 98 is equal to 98000

ie X x 98=98,000

To get the value of X, divide both sides by 98

X98/98 = 98,000/ 98

X = 1000

Thus, 1000 x 98 is truly equal to 98000

Left to Right

Algebra I

Coordinates (x, y)

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (21, 13)

Point (3, 13)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(3-21)^2+(13-13)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-18)^2+(0)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{324+0}$
[√Radical] Add: $\displaystyle d = \sqrt{324}$
[√Radical] Evaluate: $\displaystyle d = 18$
