6x + 2x - 9 = 7
Solve the equation and simplify the answer

Answers

Answer:

x=2

Step-by-step explanation:

6x+2x-9=7

Combine like terms on each side of the equation

8x-9=7

Add 9 to each side

8x=16

Divide by 8 on each side

x=2

Simplifying

6x + -2x + -9 = 7

Reorder the terms:

-9 + 6x + -2x = 7

Combine like terms: 6x + -2x = 4x

-9 + 4x = 7

Solving

-9 + 4x = 7

Solving for variable 'x'.

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

Add '9' to each side of the equation.

-9 + 9 + 4x = 7 + 9

Combine like terms: -9 + 9 = 0

0 + 4x = 7 + 9

4x = 7 + 9

Combine like terms: 7 + 9 = 16

4x = 16

Divide each side by '4'.

x = 4

Simplifying

x = 4

A boy moves down the hall at 1.2 m/s. When he sees his arch nemesis coming, he begins to run. After 3.2 s, he is moving at 4.4 m/s. What is his acceleration?

Answers

Answer:

1m/s²

Step-by-step explanation:

Acceleration is the change in velocity of a body with respect to time.

Acceleration = Change in velocity/time

Acceleration (a) = final velocity(v)-initial velocity(u)/time(t)

Given parameters:

final velocity v = 4.4m/s

initial velocity u = 1.2m/s

time taken = 3.2s

Required

Acceleration

Substitute the given parameters into the formula to get the acceleration

Acceleration = 4.4 - 1.2/3.2

Acceleration = 3.2/3.2

Acceleration = 1m/s²

Therefore the boy acceleration is 1m/s²

The gravitational potential energy, ‘G’ of an object is directly proportional to its height, ‘h’ above

potential energy is 2200 joules. Find
I. An equation connecting G and h.
II. The gravitational potential energy of the object when it is at a height of 22 meters above the
surface of Earth.
III. The height of the object above the surface of Earth when it has a gravitational potential
energy of 3025 joules.

Answers

Answer:

see explanation

Step-by-step explanation:

Given that G is directly proportional to h then the equation relating them is

G = kh ← k is the constant of proportion

To find k use the condition h = 40 when G = 2200, then

2200 = 40k ( divide both sides by 40 )

55 = k

1

G = 55h ← equation of proportion

11

When h = 22, then

G = 55 × 22 = 1210 joules

111

When G = 3025, then

3025 = 55h ( divide both sides by 55 )

h = 55 m

A cone of radius 10 cm and height 16 cm is divided into two parts by a plane through the midpoint of its
axis parallel to its base. Find the ratio of the volumes of the two parts?

Answers

Answer:

The ratio of their volumes (the top to bottom half) is 1/7

Step-by-step explanation:

The given parameters are;

The radius, r, of the cone = 10 cm

The height of the cone = 16 cm

The point at which the cone is divided = The midpoint of the its axis and parallel to its base

The ratio of the of the volume of the two parts is given as follows;

The volume, V of the entire cone = 1/3 × Base area (π·r²) × Height, h

Therefore;

V = 1/3 × π × 10² × 16 =1600·π/3 =  1675.52 cm³

The height at which the cone is divided = 16/2 = 8 cm

The height, h₁ of the uppermost divided cone = 8 cm

The ratio of the radius to the height of the cone = 10/16 = 5/8

The radius r₁, of the uppermost divided cone = The height of the uppermost divided cone × The ratio of the radius to the height of the cone

∴ r₁ = 8 × 5/8 = 5 cm

The volume, V₁, of the uppermost divided cone = 1/3 × (π·r₁²) × h₁

∴ V₁ = 1/3 × π × 5² × 8 = 200·π/3 = 209.44 cm³

Which gives;

The volume of the lower cone, V₂ =  V - V₁

V₂ =  1675.52 cm³ - 209.44 cm³ = 1400·π/3 = 1466.1 cm³

The ratio of their volumes V₁ : V₂ = V₁/V₂ = (200·π/3)/(1400·π/3) = 209.44/1466.1 = 1/7.

7) Tom is deciding whether or not he should become a member of the gymſto use their basketball courts. The
membership cost is $135. Members pay $2 to rent out the basketball courts. Non-members can rent the court also, but
they have to pay $11 each time. How many times would Tom need to rent the court in order for it be cheaper to be a
member than a non member?

Answers

Answer:

15 times for it to be equal, 15+ to be cheaper

Step-by-step explanation:

135+2x=11x

135=9x

135/9=x

15=x

135+2(15)=165$

11(15)=165$

Answer:

16 times

Step-by-step explanation:

Create an inequality where x represents the number of times he rents out the court:

2x + 135 < 11x

Solve for x:

135 < 9x

15 < x

So, Tom would have to rent the court out 16 times for it to be cheaper

Sherie bought a beach towel that normally costs $44 but was on sale for half price. She also bought a beach hat that was on sale for $12 off. Before tax, her total cost was $38. What was the regular price of the beach hat?
$22
$28
$48
$56

Answers

Answer:

$28

Step-by-step explanation:

The towel was $44 but at 1/2 off would be $22.

Her total cost was $38 so we subtract $22 from $38 to find how much she paid for the beach hat.

$38-$22 = $16

We add $12 to $16 to find the original price of the hat.

$16+$12 = $28

Solve by factoring:

5x^2 + 19x + 12 = 0

Answers

When solving polynomial equations, first set the equation

equal to zero, then check for a Greatest Common Factor.

Since there is no greatest common factor, this will make life a

little bit more difficult because we will have to factor the trinomial.

First, find all possible factors for constant term.

I have listed these in red below.

Make sure to reverse the factors since in each binomial,

the first term is different so we need to reverse the factors.

The factors of 5x² will just be 5x and z.

After finding factors for the constant and the leading

coefficient for your trinomial, we can eliminate some factors.

If you have an odd coefficient on the middle term,

you can eliminate any pairs of even factors.

So the group I crossed out in purple below will be eliminated.

Another strategy is to use factors a little closer together.

So I would go with the 4 and 3 group.

Surely enough, our trinomial does factor with the 4 and 3.

Now set the factored trinomial equal to 0.

Then use zero product property and you have your answer.

Answer:

-0.27

Step-by-step explanation:

5x^2=25x

25x+19x=44x

Answer:

Step-by-step explanation:

Let it be:

30% solution = x5% solution  = y

then

10% solution = x + y

----------

Amount of acid:

0.3x + 0.05y = 0.1(x+y)0.3x + 0.05y = 0.1x + 0.1y0.2x = 0.05y20x = 5y4x = yx/y = 1/4

So the ratio of 30% solution to the 5% solution is 1:4

Answer:

  1 : 4

Step-by-step explanation:

For a problem of this nature, a simple diagram makes the solution trivially easy. In the attached, the constituent concentrations are listed on the left, the solution concentration is in the middle, and the numbers on the right are the differences along the diagonals. These are the ratios of the respective solutions on the left.

That is, the ratio of 30% solution to 5% solution is 5 : 20 or 1 : 4.
