5X-50+2X+80-X=180..............
JulsSmile [24]

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!

A random sample of 12 chemists from Washington stats shows an average salary of $39,420 with a standard deviation of $1659. A ra
cestrela7 [59]

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

The inequality -15<-6 is given. Write the inequality you get when you perform the following operation:
Anna35 [415]

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.
