Answer:
The decimal of 4/7, when rounded to the hundredths, is 0.57. The percentage of 4/7, when rounded to the nearest hundredths, is 57.14%
Step-by-step explanation:
To get the decimal, you have to divide 4 by and you'll get your answer.
For the percentage, when rounded to the hundredths, you place the decimal two spots to the right (.57 turns into 57.14).
Ok so i would do 4x7x3 which equals 84

Answer:
x = 1/2 y = -1/3
Step-by-step explanation:
Split it into 2 equations:
10x-9y=8
and
21y+15x=0.5
10x - 9y = 8
Step 1: Divide both sides by 10:
x = (8+9y)/(10)
Substitute x = (8+9y)/(10) into 21y+15x=0.5 :
21y + (3(8+9))/(2) = 0.5
Solve for y
<u>y= -1/3</u>
Substitute y= -1/3 into x = (8+9y)/(10)
<u>x = 1/2</u>

Answer:
9:00pm
Step-by-step explanation:
If now is 5:00 am
After 1000hrs
24hrs makes a day
1000hrs = 1000/24 = 41 days remainder 16hrs
Therefore 5:00 + 16 hrs = 2100 hr
= 9:00pm

A system of equations for this would be
19x + 11y = 273
and
12x + 17y = 283.
X is the amount of minutes to solve one long division problem and y is the amount of minutes to solve a graphing problem.
How To Solve This System of Equations.
Multiply both by 17 and 11 respectively for them to have the greatest common factor for y. So now both equations are:
323x + 187y= 4641
132x + 187y= 3113.
Subtract both equations and you have left:
191x = 1528.
Divide both sides by 191 and you find x.
X = 8.
Answer
It takes Sally 8 minutes to do one Long Division Problem.
Hope this helped. ;)
