All the possible values of t in the inequality - 3 < t < 2 is,

t = - 2, - 1, 0, 1

Used the concept of inequality that states,

A relation by which we can compare two or more mathematical expressions is called an inequality.

Given that;

The inequality is,

- 3 < t < 2

Here the given inequality means all the values of t are lies between - 3 and 2.

That is,

t = - 2, - 1, 0, 1

Therefore, the value of t are t = - 2, - 1, 0, 1

From the given figure, we can infer that ~

(by linear pair)

now, let's solve for x ~

And, we can see that 2x = y (by alternate interior angle pair)

So, let's find the value of y ~

Answer:

x = 40

3x - 20 = 100

2x = 80

y = 80

2x - 15 = 65

Step-by-step explanation:

The angles 3x - 20 and 2x are a linear pair, so they are supplementary. Their measures has a sum of 180°.

Angles 2x and y are alternate interior angles, so they are congruent.

Once we find the value of x, we can find the measure of angle 2x - 15.

3x - 20 + 2x = 180

5x = 200

x = 40

3x - 20 = 3(40) - 20 = 120 - 20 = 100

2x = 2(40) = 80

y = x = 80

2x - 15 = 2(40) - 15 = 80 - 15 = 65

Step-by-step explanation:

[tex]\frac{3x-3}{5}[/tex] = [tex]\frac{2x-2}{4}[/tex] ( cross- multiply )

4(3x - 3) = 5(2x - 2) ← distribute parenthesis on both sides

12x - 12 = 10x - 10 ( subtract 10x from both sides )

2x - 12 = - 10 ( add 12 to both sides )

2x = 2 ( divide both sides by 2 )

Answer:

16 pots

Step-by-step explanation:

Laura wants to place a pot every 3/4 (0.75)m

The length she wants to cover is 12m

So all we must do is divide

1) 12/0.75 (I converted the fraction to a decimal cause its easier)

2) 12/0.75 = 16

3) which means for each 3/4 there will be one pot so there is 16 pots in total

A) The monthly percentage rate of Felix is;

B) The monthly percentage rate of Oscar is;

C) The amount that Oscar will pay more than Felix is; $0.96

A) Felix was given a card with APR of 14%.

Thus;

Monthly percentage rate = 14%/12 = 1.63%

B) Oscar was given a card with an APR of 21%. Thus;

Monthly percentage rate = 21%/12 = 1.75%

C) We are told that each of them had an average daily balance of $800 for a specific month.

Thus;

Amount paid by Felix = 800 * 1.63%

Amount paid by Felix  = $13.04

Amount paid by Oscar = 800 * 1.75%

Amount paid by Oscar = $14

Difference in Payments = $14 - $13.04 = $0.96

Thus, Oscar pays $0.96 more than Felix.

a. felix: 14/12 = 1.167% (round to nearest hundredth = 1.17%)

b. oscar 21/12 = 1.75% (no need to round here)

c.

felix: (1.17/100) x 800 = 9.36

oscar: (1.75/100) x 800 = 14.00

14.00 - 9.36 = 4.64

oscar will pay $4.64 more than felix.

Answer:

x = -6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

9(x+5)=−9

(9)(x)+(9)(5)=−9(Distribute)

Step 2: Subtract 45 from both sides.

Step 3: Divide both sides by 9.

Hello there! :)

9(x+5)=-9

Use the Distributive Property:

9(x+5)=-9

9x+45=-9

9x=-9-45

9x=-54

Divide both sides by 9:

x=-6

Answer:

120° , 80° , 90°

Step-by-step explanation:

The sum of the inner angles of a triangle is one hundred and eighty degrees. and as the diagram shows, The AB is equal to AC so angle ABC is equal to angle ACB so Angle A is 180°-(30°×2)=120°

you can get the second follow the above steps

and the third one is 2x+x+x=180°

so 4x=180°

so x=45°

so 2x=90°

Q.17) Given info:- In ∆ABC , AB = AC where, angle A = x°, angle B = 30°and angle C = ?°. Find the value of X in triangle ABC ?

Explanation:

Given that

ABC is a triangle

angle A = x°

angle B = 30°

angle C = ?°

And

AB =AC

We know that

In a triangle Angles opposite to equal sides are equal.

⇛Opposite angle to AB = Opposite angle to AC

⇛angle B = angle C

⇛angle B & C = 30°

We know that

The sum of all angles in a triangle is 180°

⇛ angle A + angle B + angle C = 180°

⇛30° + x° + 30° = 180°

⇛60° + x° = 180°

⇛x° = 180°÷60 = 180°:60

⇛x° = 180°/60

⇛x° = 3°

Now,

⇛angle A = x = 3°

⇛angle B = 30°

⇛angle C = 30°

Answer: The value of x for the given problem is 3°

Q.18) Given info:- In ∆ABC , AB = AC where, angle A = x°, angle B = 50°and angle C = ?°. Find the value of X in triangle ABC ?

Explanation:

Given that

ABC is a triangle

angle A = x°

angle B = 50°

angle C = ?°

And

AB =AC

We know that

In a triangle Angles opposite to equal sides are equal.

⇛Opposite angle to AB = Opposite angle to AC

⇛angle B = angle C

⇛angle B & C = 50°

We know that

The sum of all angles in a triangle is 180°

⇛ angle A + angle B + angle C = 180°

⇛ x° + 50°+50° = 180°

⇛x° + 100 = 180°

⇛x° = 180°÷100° = 180°:100°

⇛x° = 180°/100

⇛x° = 18°

Now,

⇛angle A = x = 18°

⇛angle B = 50°

⇛angle C = 50°

Answer: The value of x for the given problem is 18°

Q.19) Given info:- In ∆ABC , AB = AC and angle A = 2x°, angle B = x°, angle C = x°. Find the value of X in triangle ABC ?

Explanation:

Given that

ABC is a triangle

angle A = 2x°

angle B = x°

angle C = x°

And

AB =AC

We know that

In a triangle Angles opposite to equal sides are equal.

⇛Opposite angle to AB = Opposite angle to AC

⇛angle B = angle C

⇛angle B & C = x°

We know that

The sum of all angles in a triangle is 180°

⇛ angle A + angle B + angle C = 180°

⇛x° + 2x° + x° = 180°

⇛2x° + 2x° = 180°

⇛4x° = 180°

⇛x° = 180°÷4 = 180°:4

⇛x° = 180°/4

⇛x° = 45°

Now,

⇛angle A = 2x = 2(45) = 90°

⇛angle B = 45°

⇛angle C = 45°

Answer: The value of x for the given problem is 45°
