How old would someone be if they were born on the 30th october 1992 ????

Answers

today is March, 19th 2016
so from 1992 have been: 2016 - 1992 = 24 years
but the date is from October 30th, so we are not at 24 years just yet, we are at 23 years and the months and days since last 30th October, that is:
November + December + January + February = 4 months
and some days more, 19 days because today is 19th, so the total is:
23 years, 4 months, 19 days
simple its 2016 and they are born on 1992 so 2016-1992 = 24. but there birthday is in October so they will be 23

How many times can 4500 go into 5 ?

Answers

since we have 2 zeros we can take them off and add them back on when we are done.

5 goes into 45 9 times.

now lets add the two zeros back on

900

5 goes into 4500 900 times
   
                                                    
1 way

(4500)/(5) = (45* 100)/(5) = (9 * 100)/(1) = 900

4500 = 4000 + 500

we share thousands (4 * 1000)
4000 : 5 = 800

we divide hundreds ( 5 * 100)
500 : 5 = 100

add quotients
800 + 100 = 900

What is y=2/3x-5 in standard form?

Answers

9514 1404 393

Answer:

  2x -3y = 15

Step-by-step explanation:

Add 5-y to put the variables on the same side of the equal sign. Then multiply by 3 to clear the fraction.

  5 = 2/3x -y

  15 = 2x -3y

  2x -3y = 15 . . . . standard form

Final answer:

The equation y = 2/3x - 5 can be converted to standard form (Ax + By = C) by clearing the fraction and rearranging terms, resulting in 2x - 3y = 15.

Explanation:

The equation y = 2/3x - 5

is currently in slope-intercept form (y = mx + b), where

m is the slope

and b is the y-intercept. To convert this equation to standard form (Ax + By = C), we want to get rid of any fractions and rearrange the terms.

Step 1: Clear the fraction by multiplying every term by 3, resulting in: 3y = 2x - 15.

Step 2: Rearrange the terms to get the x and y terms on one side and the constant on the other: 2x - 3y = 15.

Therefore, the standard form of y = 2/3x - 5 is 2x - 3y = 15.

Tanesha’s utility and telephone bills for the month totaled $150. The utility billwas 4 times as much as the telephone bill. How much was each bill?

Answers

X represents the cost of the phone bill

4x + x = 150
5x = 150
X = (150/5)
X = 30

Therefore the telephone is $30 and the utility bill is $120
