-45 - 9n = -81
-9n = -81 + 45
-9n = -36
n = -36/-9
n = 4
Hope this helps you. :)
Answer:
4=n
Step-by-step explanation:
-81= -45-9n
+45 +45
-36= -9n
÷ -9 ÷-9
4= n
substitute:
-81= -45 -9 (4)
-81= -45 -36
-81= -81

Which of the following shapes are squares ? Please choose 2 correct answers !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!
Answer:
B,D
Step-by-step explanation:
Answer:
Hello again! Your answer would be B and D
Step-by-step explanation:
A square is a shape with 4 sides and all of them have to equal. Right away you can see that D is without needing to look at it. You might think that B is not because of its angle but if you turn your paper/computer to the side a bit you can there see that it is square. C and A are not because of their unequal sides. Yes, they do have four sides but they are non-equal.

x(x+1)-y(y+1)
Answer:
[tex](x - y)(x + y + 1)[/tex]
Step-by-step explanation:
[tex]x(x + 1) - y(y + 1)[/tex]
[tex]=> x^{2} + x - y^{2} - y[/tex]
Lets re-arrange it.
[tex]=> x^{2} - y^{2} + x - y[/tex]
Now , lets expand x² - y².
[tex]=> (x + y)(x - y) + (x - y)[/tex]
Taking ( x - y ) common ,
[tex]=> (x - y)(x + y + 1)[/tex]
Answer:
[tex]x(x + 1) - y(y + 1) \\ → {x}^{2} + x - {y}^{2} - y \\→( {x}^{2}- {y}^{2}) + (x - y) \\→ (x - y)(x + y) + (x - y) \\→ \boxed{ (x - y)(x + y + 1)}✓[/tex]

The ratio of money in Brian's wallet to Colin's wallet one day was 7:2.
Brian spent £39 that day.
Brian now had £4 less than Colin.
How much did they initially have altogether?
Answer:
£30
Step-by-step explanation:
Let Brian initially had money in his wallet = £x
and Colin had the money = £y
Since ratio of money in Brian's wallet to Colin's wallet was 5 : 1
Therefore,
⇒ x = 5y -------(1)
Brian spent £27 that day, so money left with him = £(x - 27)
After spending the money Brian had £3 less than Colin.
(x - 27) = (y - 3)
x = y + 27 - 3
x = y + 24 -------(2)
Now we equate the equations (1) and (2) for the value of x,
5y = y + 24
5y - y = 24
4y = 24
y = £6
From equation (2),
x = 6 + 24
x = £30
Therefore, Brian initially had £30.
i hope this helps

-4(3k-6)-4k = -8k+24-4k
can yall solve this plz I want to go to sleep but my mom won't let me until I get my homework done
Answer:
0 (undefined)
Step-by-step explanation:
distribute on the left side first:
-4(3k-6)-4k
so -12k+24-4k
combine like terms
-16k+24
now the right side
-8k+24-4k
combine like terms
-12k+24
so it'll look like this
-16k+24=-12k+24
add -12k to the left
-4k+24=24
so then subtract 24
that'll leave you with 0
3. What is the sum of the interior angles of a polygon with 32 sides?
Answer:
Step-by-step explanation:
To find the sum of an interior angle of a polygon, you have to follow these steps:
Interior angle= ( n - 2 ) ×180° all over n
So interior = ( 32 - 2 ) × 180° all over 32
Interior = 30 × 180 all over 32
Therefore your interior angle should be 168.75°

Answer:
x = 1
Step-by-step explanation:
1/2(8x-6) = -1/3(9x-12) distribute
4x-3 = -3x+4 add 3x to both sides
7x-3 = 4 add 3 to both sides
7x = 7 divide by 7 on both sides
x = 1

The answer is b becasue its subtraction
Step-by-step explanation:
Polynomials are closed under an operation if it produces a polynomial.
5x⁴, x² + 2x + 1 and x³ - 10x³ + 28x - 15
are all polynomials of x.
x - 3 + (-3)/(x - 2) is not a polynomial because x can be found in the denominator of a fractional term.
The answer is Option A.

Rykers’ regular pay rate is $11.97 an hour. He is paid time-and-a-half for hours worked over 40 hours in a week, including weekend work. He worked these hours from Monday through Saturday last week: 10.25, 6.25, 9.25, 12, 12.25, 6.25. What was his gross pay for the week?
Answer:
$770.65
Step-by-step explanation:
