Can i please get help with this question?

Answers

Answer 1

Answer:

The answer is 3.88888888889

Answer 2

Answer:

The answer is 35/9

You first would remove the parentheses

Next you see that there is a subtraction symbol and a negative symbol right beside each other. You cant have 2 negatives side by side, so you change the symbol to addition

The problem then looks like this: 5/9 + 3 1/3

To make the problem easier you change the mixed number (3 1/3) to an improper fraction which is 10/3

Because its 5/9 + 10/3 you multiply 10 and 3 and get 30, and you keep the LCD (least common denominator) which is 9

Finally you add 5 + 30 = 35 and have 9 as your denominator

35/9 or 3 8/9

What is the simplified form of the equation fraction 4 over 5 n minus fraction 3 over 5 equals fraction 1 over 5 n?n = 1
n = −3
n = fraction 3 over 4
n = fraction 1 over 4

Answers

Simple...

so you have...

$(4)/(5) n- (3)/(5) = (1)/(5) n$

You want to isolate the variable,n,....

so subtract....

$(4)/(5) n- (3)/(5) = (1)/(5) n$
$- (4)/(5)n$ $-(4)/(5) n$

Leaving you with.....

$-(3)/(5) = -(3)/(5) n$

Now, divide....

$(- (3)/(5) )/( -(3)/(5) ) = (- (3)/(5)n )/( -(3)/(5) )$

Making n=1

Thus, your answer.

The measures of exterior angles of a regular polygon with n numbers of sides ____ as n increases

Answers

decrease

The exterior angles of a polygon add up to 360 degrees, so the measure of each exterior angle of an n-sided regular polygon is given by 360/n. As n increases, 360/n will decrease.

Exterior angle = 360 / n

where n = number of sides of the regular polygon.

So when n increases, the exterior angle reduces.

So:

The measures of exterior angles of a regular polygon with n numbers of sides decreases as n increases

Hope this explains it.

Which unit of measurement would be the most appropriate to measure how much water is in a lake?A : Liter

B : Kiloliter

C : Gram

D : Kilometer

Answers

B would be most appropriate to measure a large volume of water such as in a lake- KILOLITER

Kiloliter since the volume of water is large.

Grams and kilometer are for mass and distance respectively

3x + 5y = 7
4x + 3y = 2

Both x and y have to be the same numbers!

Answers

Simultaneous Equations:
(3x + 5y = 7)×(-3)
(4x + 3y = 2)×(5)

-9x - 15y = -21
20x+15y =10 (-15y and and+15y cancels out)

11x = -11
$(11x)/(11)$ = $(-11)/(11)$ (11 and 11 cancels out)
x= -1
substitute the x we found into either original expressions

3(-1) + 5y = 7
-3 + 5y = 7
+3 -3+ 5y = 7+ 3
5y = 10
$(5y)/(5)$ = $(10)/(5)$ (5 and 5 cancels out)
y=2
Check it!
4(-1)+3(2) = 2
-4 + 6 = 2
2 = 2

3(-1) + 5(2) = 7
-3 + 10 = 7
7 = 7

x= -1
y= 2

i think there was a something wrong in you question because the answer does not be the same as you want
