help plz I dont remember how to solve these

Answer:

3( y - 2) + 2y =9

Step-by-step explanation:

It equals 3.

Answer:

y=3

Step-by-step explanation:

3(y-2)+2y=9

3y-6+2y=9

Isolate the variable y by transposing

3y+2y=6+9

5y=15

Simplify

y=3

The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Consider all positive integers that are multiples of 10 and are less than or equal to 200.

Let the number of the positive integer that are multiples of 10 be x. Then the equation will be

10x ≤ 200

Then the value of the x will be

x ≤ 20

The set of numbers is given below.

Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}

The set which is divisible by 15 will be

Set = 6 {30, 6,0 90, 120, 150, 180}

Then the fraction of those integers are multiples of 15 will be

⇒ 6 / 20

⇒ 3/10

The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

The altitude of the right triangle is the geometric mean of the 2 parts of the side it separates.

a. The answer would be sqrt(18*32)=24

The question to the second question can be answered by using the Pythagorean theorem.

32^2+24^2=1600=40^2

b. The answer would be sqrt40^2=40

The beach, the parking lot and the refreshment stand are illustrations of similar triangles.

(a) The distance between the spot and the parking lot

Represent this distance with d.

So, the equivalent ratio is:

[tex]\mathbf{32:d = d : 18}[/tex]

Express as fractions

[tex]\mathbf{\frac {32}d = \frac{d}{ 18}}[/tex]

Cross multiply

[tex]\mathbf{d \times d = 32 \times 18}[/tex]

[tex]\mathbf{d^2 = 576}[/tex]

Take square roots

[tex]\mathbf{d = 24}[/tex]

Hence, the distance between the spot and the parking lot is 24 m

(b) The distance between the refreshment stand and the parking lot

Represent this distance with d.

Using Pythagoras theorem we have:

[tex]\mathbf{d^2 = 32^2 + 24^2}[/tex]

[tex]\mathbf{d^2 = 1600}[/tex]

Take square roots

[tex]\mathbf{d = 40}[/tex]

Hence, the distance between the refreshment stand and the parking lot is 40 m

The solution to the inequality, 4x^2 - 25 < 0 is determined as x < 5/2.

The solution to the inequality is obtained by solving the inequality as shown below;

4x^2 - 25 < 0

add 25 to both sides of the equation;

4x² < 25

divide both sides by 4

x² < 25/4

take square root of both sides

x < 5/2

Thus, the solution to the inequality, 4x^2 - 25 < 0 is determined as x < 5/2.

Answer:

For right angle triangle,

we use Pythagoras theorem that is:

[tex]c^{2} =a^{2} +b^{2}[/tex]

c = [tex]\sqrt{a^{2} +b^{2} }[/tex]

For question 1:

c = ?

a = 40

b = 9

putting them in formula,

c = [tex]\sqrt{40^{2} + 9^{2} }[/tex]

c = 41

For question 2:

c = ?

a = 12

b = 13

putting them in formula,

c = [tex]\sqrt{12^{2} + 13^{2} }[/tex]

c = approximately 17.69181

For question 3:

c = 35

a = 20

b = ?

putting them in formula,

[tex]c^{2} =a^{2} +b^{2}[/tex]

[tex]35^{2} = 20^{2} + b^{2}[/tex]

1225 = 400 + [tex]b^{2}[/tex]

[tex]b^{2}[/tex] = 1225 - 400

[tex]b^{2}[/tex] = 825

[tex]\sqrt{b^{2} } = \sqrt{825}[/tex]

b = 5 [tex]\sqrt{33}[/tex]

For question 4:

c = 37

a = 20

b = ?

putting them in formula,

[tex]c^{2} =a^{2} +b^{2}[/tex]

[tex]37^{2} = 20^{2} + b^{2}[/tex]

1369 = 400 + [tex]b^{2}[/tex]

[tex]b^{2}[/tex] = 1369 - 400

[tex]b^{2}[/tex] = 969

Taking square root on both sides

b = 31.12

The computer will be worth $200.

Step-by-step explanation:

A quarter of $800 is $200, so the computer loses $200 dollars in value every two years. Since 6÷2 is 3, you multiple $200 by 3 to get $600. You then subtract $600 from $800 and get $200.

Answer: The value of the computer at time 0 is $800

The value of the computer at time 1 is $600

The value of the computer at time 2 is $450

The value of the computer at time 3 is $337.50

The value of the computer at time t is (n - 1) x 3/4

These triangles can be proven congruent through AAS, or angle, angle, side. This means that two angles and one nonincluded side are congruent. Two sides are marked as congruent through a tick mark, and one angle pair is marked by one arc on each angle. We also know that the middle angles, that are connected, are congruent because they are vertical angles. Therefore, they are congruent, which can be proven by AAS.
