Answer:

unknown number is [tex]\frac{1}{9}[/tex]

Step-by-step explanation:

let x = unknown number

Therefore,  [tex]\frac{1}{3} x=\frac{1}{27}[/tex]

Multiply both sides by 27:  [tex]9x=1[/tex]

Divide both sides by 9:  [tex]x=\frac{1}{9}[/tex]

Answer: 9y + 7 = y

Explanation:

The phrase, "nine times a number y" is "9y" in the form of an equation. When any term is by a number, they are meant to be multiplied together. So, "9y" means "9 times y".

The phrase, "plus seven" simply means to add seven.

The phrase, "equal to number y" is "= y" because "number y" refers to that term.

And so, all together, you get 9y + 7 = y.

Answer:

A = 120

B = 102

Step-by-step explanation:

Assume A had x runs

So B had [tex]x-18[/tex] runs {the total runs is 222}

A + B = 222

2x = 240

x = 120

B: x - 18 = 120 - 18 = 102

Answer:

80

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle:

30 + 4x + 2 = 8 + 6x add like terms

32 + 4x = 8 + 6x move like terms to the same side of the equation:

32 - 8 = 6x - 4x

24 = 2x divide both sides by 2

12 = x now to find the angle replace x with 12

8 + 6*12 = 80

Answer:

C)   y = 5

Step-by-step explanation:

Equation of a line in slope-intercept form:  y = mx + b

(where m is the slope (gradient) and b is the y-intercept)

If the line is perpendicular to the y-axis, the line will be parallel to the x-axis (horiztonal) and so the slope is zero.

Therefore, y = (0)x + b

⇒ y = b

We are told that the line passes through point (-4, 5).  Therefore, the y-intercept is 5.

So the equation of the line is:  y = 5

Answer:

kilograms

Step-by-step explanation:

theoretically, a bus cant be measured in grams, because its too light and unrealistic.

The school bus has a mass of about 8000 kilograms.

"Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration (change of velocity) when a net force is applied."

"The kilogram is the base unit of mass in the International System of Units (SI), the metric system, having the unit symbol kg."

Theoretically, a bus can't be measured in grams. Because its not too light to lift and heavy in weight.

∴ The school bus has a mass of about 8000 kilograms.
