Answer:

If you wanted to simplify the equation:

9y - 30 = 6

If you wanted to solve for y:

y = 4

Step-by-step explanation:

3(3y - 10) = 6

9y - 30 = 6

Add 30 to both sides of the equation:

9y - 30 + 30 = 6 + 30

Simplify:

9y = 6 + 30

9y = 36

Divide both sides of the equation by 9:

9y ÷ 9 = 36 ÷ 9

Cancel terms that are in both the numerator and denominator:

y = 36 ÷ 9

y = 4

The manufacturer of a laser printer reports the mean number of pages a cartridge will print before it needs replacing is 12,200.

Svetllana [295]

Answer:

14110

Step-by-step explanation:

Let x = number of pages ;

μ = 12200 ; σ = 820

Zscore = (x - μ) / s

Zscore = (x - 12200) / 820

Zcritical at 99% confidence, for a 1 - tail test is 2.33

Hence, Z at 99% = 2.33

Put Zscore = 2.33

Zscore = (x - 12200) / 820

2.33 = (x - 12200) / 820

2.33 * 820 = x - 12200

1910.6 = x - 12200

1910.6 + 12200 = x

x = 14110.6

x = 14111

The number of pages the manufacturer should advertise is 14,110

Write and solve an equation that represents the following:<br> Twenty more than a number is eighteen

ArbitrLikvidat [17]

Salutations!

Let the number be $x$

The equation would be: $x+20=18$

Lets solve this!

We need to always keep the variables aside, and the numbers aside.

$x=20-18$

$x=2$

Hope I helped (:
