The interior angle of C is 180 - 142 = 38
The three interior angles add up to 180°
(2x - 15) + (x - 5) + 38 = 180
3x - 20 + 38 = 180
3x + 18 = 180
3x = 162
x = 54
The measure of angle ABC = x - 5 = 54 - 5 = 49
For JKL:
The interior angle of L is 180 - 100 = 80°
The 3 interior angles add up to 180°
(2x + 27) + (2x - 11) + 80 = 180
4x + 16 + 80 = 180
4x + 96 = 180
4x = 84
x = 21
The measure of angle JKL is 2x - 11 = 2(21) - 11 = 42 - 11 = 31°

10.Step-by-step explanation:
Explanation:
[tex]12 - 6 + 4[/tex]
In order to solve this, we must use PEMDAS.
This is because there are more than one operations involved.
PEMDAS is the order in which you must solve the operations.
PEMDAS STANDS FOR:
ParenthesisExponential Notation (exponents)Multiplication/division (do whichever comes first)Addition/subtraction (do whichever comes first)Solve.
Now, using PEMDAS, I will solve.
There are no parenthesis.
There are no exponents.
There is no multiplication nor division.
There is addition and subtraction.
[tex]12-6+4[/tex]
[tex]12-6=6[/tex]
[tex]6+4[/tex]
Lastly, there is addition.
[tex]6+4=10[/tex]
Conclude:
I, therefore, believe [tex]12-6+4=10.[/tex]
You did not clarify the answers of Jagan nor Mithun.
So, whichever person got the answer of 10 is correct.

On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with the number a. For example b = 2; when a = -2 which equation represents this direct variation between a and b? O b= -a O-=-a Ob-a=0 Ob(-a) = 0
Answers
Answer:
b = -a
Step-by-step explanation:
If a and b are both positions from 0, we need to write an equation that relates both positions. The problem is explaining that the position of a is opposite to the position of b.
If a = 2; b = -2. If a = 1000; b = -1000.
If a = -x; b = x. Then:
-a = x
-a = x and b = x, that means:
b = -a

Pay attention to the behavior of the asymptotes. If the asymptotes are approaching a certain x-value or y-value, then that value is undefined for the function.

As x approaches ∞ and -∞, then y approaches 0, which is our horizontal asymptoteAs y approaches ∞ and -∞, then x approaches 0, which is our vertical asymptoteSee the graph for a visual.

What is the atmospheric pressure?
a. 4.7 pounds per square inch
b. 13.2 pounds per square inch
c. 1.7 pounds per square inch
d. 14.7 pounds per square inch
Answers
Answer:
D
Step-by-step explanation:
The atmospheric pressure is about 101325Pa.
Pascal is a unit for pressure and since pressure can be defined as force/ area, the pressure can also be written as 101325 N/m².
1 m² ----- 101325 N
Pounds is a unit for mass, so let's relate force (Newtons) to mass.
[tex]\boxed{F = ma}[/tex]
☆ where F= force, m= mass and a= acceleration due to gravity
Since the gravitational field strength is about 9.8 N/kg on earth, a= 9.8.
101325= m(9.8)
m= 10339 Kg (5 s.f.)
Since 1 kg is about 2.205 pounds,
m
= (10339 ×2.205) pounds
= 22797.495 pounds
= 22797 pound (5 s.f.)
1 m² ----- 22797 pounds
Now convert m² to in².
1 m² is about 1550 in², thus
1550 in² ----- 22797 pounds
1550 in² ----- 22797 pounds
1 in²----- 22797 ÷1550
1 in² ----- 14.708 pounds (5 s.f.)
1 in² ----- 14.7 pounds (3 s.f.)
Thus, 1 atm≈ 14.7 pounds per square inch.
