Simplifying

8x + -10 = 62

Reorder the terms:

-10 + 8x = 62

Solving

-10 + 8x = 62

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + 8x = 62 + 10

Combine like terms: -10 + 10 = 0

0 + 8x = 62 + 10

8x = 62 + 10

Combine like terms: 62 + 10 = 72

8x = 72

Divide each side by '8'.

x = 9

Simplifying

x = 9

Answer:

Your answer is 3x = 15

Step-by-step explanation:

3x = 15

Since 3 is being multiplied by x, we divide both sides by 3. 3x/3 cancels out, and you're left with x.

15/3 = 5

x = 5

This is my take using algebraic methods.

Answer:

The value is $\sigma = 8.5$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 9.7$

The proportion is $P(X >x) = 0.2245$

The value considered is $x = 11.6$

Generally given that the speed measurement is normally distributed we have that

$P(X > 11.6) = P(\frac{ X - \mu }{ \sigma } > \frac{11.6 - 9.7}{ \sigma } ) = 0.2245$

Generally

$\frac{X - \mu}{ \sigma } = Z(The \ z -score \ of \ X )$

$P(X > 11.6) = P(Z> \frac{11.6 - 9.7}{ \sigma } ) = 0.2245$

Hence

$\frac{ 11.6 - 9.7}{ \sigma} = 0.2245$

$\sigma = 8.5$

after two years on the job, an engineer salary was $60,000. after seven years on the job, her salary was $66,000. let y represen

galina1969 [7]

Answer: y = 1200m + 57,600

Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.

So, we have (2,60000) and (7,66000)

y = mx + b

66000 = 7m + b

60000 = 2m + b (-)

________________________

6000 = 5m

m = 6000/5 = 1200

60000 = 2m + b

60000 = 2.1200 + b

60000 = 2400 + b

b = 60000 - 2400

b = 57600

y = mx + b

y = 1200m + 57,600
