Gus started with a number he multiplied by 8 subtracted 12 divided by 4 and added 7 to get 50 show how to work backward to find the starting number

Answers

Answer 1

Answer:

23

Step-by-step explanation:

This equation can be derived from the question

let a represent the initial number Gus started with

{[(a x 8) - 12] / 4 } + 7 = 50

subtract 7 from both sides of the equation

[(a x 8) - 12] / 4 } = 43

Multiply both sides of the equation by 4

(a x 8) - 12] = 172

Add 12 to both sides

8a =184

Divide both sides by 8

a = 23.

What is a factor of a polynomial?

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, A cubic polynomial 9x³ - 21x² + 12x and being divided by 3x.

So, (9x³ - 21x² + 12x)/(3x).

= 9x³/3x - 21x²/3x + 12x/3x.

= 3x² - 7x + 4.

So, The quotient when 9x³ - 21x² + 12x and being divided by 3x is

3x² - 7x + 4.

Answers

Answer:

first option

Step-by-step explanation:

In a parallelogram consecutive angle are supplementary, sum to 180, so

2a + 122 = 180 ( subtract 122 from both sides )

2a = 58 ( divide both sides by 2 )

a = 29

In a parallelogram the opposite sides are congruent, then

b + 6 = 10 ( subtract 6 from both sides )

Answer: 127.5km

Step-by-step explanation:

We are informed that Ron cycled 510km last week and that he was under the rain for the 25percent of his journey.

The distance travelled did under the rain will be gotten by multiplying 25% by 510km. This will be:

= 25% × 510

= 0.25 × 510

= 127.5km

He was in the rain for 127.5km

To do this you will multiply 2×5, to find the front area of the cube, for the top of the cube you will multiply 5×4, and for the side of the cube you will multiply 2×4. once you get the answer you will multiply it by 2 since you have a 3 dimensional shape.

A line passes through the point (-6,9) and has a slope of -5/2 . Write an equation in point-slope form for this line.

Answers

Answer:

y-9=-5/2(x+6)

Step-by-step explanation:

y-y1=m(x-x1)

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

An equation in point-slope form for this line would be y-9=-5/2(x+6).

What is the Point-slope form?

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Which is the required equation of a line in a point-slope form.

Thus,

y-y1= m(x-x1)

A line passes through the point (-6,9) and has a slope of -5/2 So,

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

Hence, an equation in point-slope form for this line would be y-9=-5/2(x+6).

From the right triangle given in the picture,

By applying tangent rule,

tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(x) = [tex]\frac{9}{15}[/tex]
