Second one sorry if i’m wrong
Hey there!
5x - 50 + 2x + 80 - x = 180
COMBINE the LIKE TERMS
= 6x + 30 = 180
SUBTRACT 30 to BOTH SIDES
6x + 30 - 30 = 180 - 30
CANCEL out: -30 - 30 because that gives you 0
KEEP: 180 - 30 because it helps solve for the x-value
6x = 180 - 30
180 - 30 = 150
NEW EQUATION: 6x = 150
DIVIDE 6 to BOTH SIDES
6x/6 P 150/6
CANCEL out: 150/6 because that gives you the result of the x-value
x = 150/6
SIMPLIFY IT!
x = 25
Therefore, your answer is: x = 25
Good luck on your assignment and enjoy your day!

Answer:
Step-by-step explanation:
Given that :
μ1 = 39420 ; σ1 = 1659 ; s1 = 12
μ2 = 30215 ; σ2 = 4116 ; s2 = 26
df1 = 12 - 1 = 11
df2 = 26 - 1 = 25
98 % confidence interval of the difference in sample means :
Pooled Variance :
S²p = ((df1 * s1²) + (df2 * s2²)) / (df1 + df2)
((11×1659^2)+(25×4116^2))÷(11+25) = 12605874.75
Standard Error :
√(S²p/n1) + (S²p/n2)
√(12605874.75/12) + (12605874.75/26)
= 1239.0847
Answer:
t= 11.50h + 6
and
t= 11.50+6+h
Step-by-step explanation:
t= total amount of wages
11.50 x h =
11.50h + 6
t= 11.50h + 6
and
t= 11.50+6+h
Step-by-step explanation:
strange, because the way you typed it, it would be absolutely correct.
If a < b and if c is a positive number, then
a/c < b/c
Dividing each side of an inequality by a positive number does not change the direction of the inequality symbol.
that is one of the defined rules.
so, did you make a mistake with a sign ? maybe the division is meant to be by -3 ?
then indeed, suddenly
5 > 2
so, please check the problem definition precisely. if your correct answer is actually wrong, then the original problem must be different than what you typed here.
