Answer: 432 or 4368

Step-by-step explanation:

multiply base and height this case 24,18. 24x18=432 or 182 x 24=4368

if you using 24 x 18 =432

if you using 182x24=4368

Answer:

(-2,-1)

Step-by-step explanation:

Since this is a reflection over the y-axis you'll keep the x-coordinate Making it (-2,?) and then since 3 is two away from y=1 on the plane you'd just count downwards two more giving you -1, so the answer is (-2,-1)

simplified equation is -4+x

x=4

Step-by-step explanation:

-4+x=0

+4

x=4

Answer:

x-4

Step-by-step explanation:

1. Rearrange terms : −(4−x)  −(−+4)  Then Distribute the negative: −(−+4)   1−4

Multiply by 1: 1−4   so x-4

Answer:

0,4

Step-by-step explanation:

did on delta math rn and got it right. basically just divide 0,12 by 1/3

ex: 0 by 1/3 and 12 by 1/3

12/3 is 4 so 0,4

Answer:

2÷ 1/3 =6

3 ÷1/2=6

4÷2/3=6

4 ÷1/2=8

12÷3/2=8

Answer:

x = 40

Step-by-step explanation:

x + 100 +  x = 180 {Straight line angles}

2x   + 100 = 180      {subtract 100 from both sides}

         2x = 180 - 100

         2x = 80      {Divide both sides by 2)

           x = 80/2

          x = 40

Answer:

x=40

Step-by-step explanation:

2x+100=180

2x=180-100

2x=80

x=40

Answer:

the pythagoream theorem, a^2+b^2=c^2

1. 13in.

2. 31.6 yd.

3. 16.1 m.

Step-by-step explanation:

c is the hypotonus (the diagonal line on a right triangle)

if you are trying to find c, you square the two sides that are given and then add them up.

For example number 1:

So 5x5=25   and    12x12=144

add those two values together, 25+144=169

the last step is to find the square root of that last sum (169)

√169 = 13.

Answer:

EC = 8/9 ft

Step-by-step explanation:

ΔADE ≈ ΔABC

set up a proportion based on corresponding sides

AD/AE = AB/AC

9/4 = 11/(4 + EC)

9(4 + EC) = 44

36 + 9EC = 44

9EC = 8

EC = 8/9

Answer:

x > 7

Step-by-step explanation:

i dont know if this is right but i think so

The solution is x > 7

The value of x from the inequality equation 3 ( x - 2 ) > 15 is x > 7

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

3 ( x - 2 ) > 15   be equation (1)

On simplifying the equation , we get

3x - 3 ( 2 ) > 15

3x - 6 > 15

Adding 6 on both sides of the inequality equation , we get

3x > 21

Divide by 3 on both sides of the inequality equation , we get

x > 21/3

x > 7

Therefore , the value of x is greater than 7

Hence , the inequality equation is x > 7

Answer: x = 0.3

Step-by-step explanation:

The required solution of a given equation would be x = 1/3  as a fraction.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

We have been given the equation as

⇒ 1/x + 1/3x = 4

Take the LCM in the above equation

⇒ (3 + 1)/3x = 4

⇒ (4)/3x = 4

Rearrange the term of variable x, and we get

⇒ (4)/(4)(3) = x

⇒ 1/3 = x

⇒ x = 1/3

Therefore, the required solution of a given equation would be x = 1/3  as a fraction.
