combine like terms on opposite side of =
(-11x )+ (-1x) = (84) + (72)
-12x = 156
divide both sides by -12 to isolate x
-12/-12 = 156/-12
x = -13
insert (-13) for x
(-11 * -13) -72 = 84 + (-13)

Answers
If each kite measures 6 inches across and 12 inches long. The square inches of the wall will be: 864 square inches.
Square inches of the wal
Diagonals= d1 and d2
First step
Area =(1/2)×(d1×d2)
Area=(1/2)×(6×12)
Area =36 in²
Second step
1 feet = 12 inches
12 feet = 12×12
12 feet = 144 in
Third step
Number of square inches=(144/6)×36
Number of square inches=24×36
Number of square inches= 864 square inches
Therefore the square inches of the wall will be: 864 square inches.

Answer:
The mean is 80.875 or 81 rounded
Step-by-step explanation:
To find the mean of any set of numbers, you need to get the values added up together and the #values (how much numbers there are).
Formula setup: amountaddedup/#numbers
✔ When we plug in the values in the formula, you will get 80.875.
The mean of the given data is 80.75.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The given data is 95, 45, 37,82 ,90,100, 91 ,78 , 67 ,84 ,85 ,85 , 82 , 91 , 93 , 92,76, 84, 100, 59 , 92, 77 , 68 and 88
Mean = Sum of the observations/ Total number of observation.
Sum of the observations = 95+ 45+37+82+90+100+91+78+67+84+85+85 +82 +91+93+92+76+84+100+59+92+77+68+88

The cost of an order of 1 hamburger and 2 orders of fries cost which Nathaniel and Liam bought is $6.5.
What is system of equation?A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.
Let the cost of 1 hamburger is x dollar and 2 orders of fries is y dollars. Nathaniel bought 3 hamburgers and 2 orders of fries for $12.50. Thus,
[tex]3x+2y=12.5[/tex]
Solve this equation as,

Liam bought 2 hamburgers and 4 orders of fries for $13. Thus,
[tex]2x+4y=13[/tex]
Put the value of y in this equation and solve it further,
[tex]2x+4(\dfrac{12.5-3x}{2})=13\\2x+25-6x=13\\-4x=13-25\\-4x=12\\x=\dfrac{12}{4}\\x=3[/tex]
Put this value of x in equation 1,

Answers
Answer:
13. 3
Step-by-step explanation:
Given Points:
(x1= 4, y1 = 11), (x2= - 9, y2 = 8)
Distance Formula:
d² = (x2 -x1)² + (y2 -y1)²
Substitute and Calculate:
d² = ( -9 -4)² + ( 8 -11)²
d² = (-13)² + (-3)²
d = √(169+9)
d = √178
