Answer:
x=4/3
Step-by-step explanation:
9x+8=12x+4
Subtract 8 from both sides;
9x+8-8=12x+4-8
Simplify;
9x=12x-4
Subtract 12x from both sides;
9x-12x=12x-4-12x
Simplify;
-3x=-4
Divide both sides by -3
-3x/-3=-4/-3
Simplify;
x=4/3

Answers
Answer:
1
Step-by-step explanation:
The answer is actually just positive 1.
Absolute value is the direct opposite of a number with a positive value on a number line. However, the absolute value is always answered in a positive form of the number meaning that no matter what the number is (even if it's a positive number) the answer will always be that same number, but in positive form.
Remember, if a number is in between two of these " | " then the answer will be that same number but in positive form.
Hope this helps and have a nice day.

Step-by-step explanation:

n1 = 10 ; n2 = 8 ; s1 = 0.5 ; s2 = 0.7 ; x1 = 3.1 ; x2 = 2.7
Confidence interval, two - sample, t procedure ;
μ1 - μ2 = (x1 - x2) ± Tcritical*S
S = sqrt[(s1²/n1) + (s2²/n2)]
S = sqrt[(0.5^2/10) + (0.7^2/8)]
S = sqrt[0.08625]
S = 0.2937

Hey there!
the exterior angles of a quadrilateral add up to equal 360
so 360=2x+40+4x+3x+x+50
step 1 combine like terms
2x+4x+3x+x=10x
50+40=90
now we have
360=10x+90
step 2 subtract each side by 90
360-90=270
90-90 cancels out
now we have 270=10x
step 3 divide each side by 10
270/10=27
we're left with
