Answer:

Valid

Step-by-step explanation:

3(x-4)=x+4              Given

3x-12=x+4                Distribute

2x=16                      Subtract x from both sides and add 12 to both sides

x=8                           Divide each side by 2.

Hey there!

3(x - 4) = x + 4

3(x) + 3(-4) = x + 4

3x - 12 = x + 4

3(8) - 12 = 8 + 4

24 - 12 = 8 + 4

12 = 12

Therefore, this makes this statement TRUE

Good luck on your assignment and enjoy your day!

Answer:

x = 9

Step-by-step explanation:

4∣x−9∣+9 = −3∣x−9∣+9

cancel equal terms on both sides of the equation

the statement is true but only if both sides equal 0

solve the equation for x

divide both sides of the equation by 4

when the absolute value of x - 9 equals 0, then x - 9 = 0

move the constant to the right side and change it´s sign

so the answer would be x = 9

Answer: it's x=9

80+80=160  

80+80+80=240

240 >160

so no it is not equal

thank you for your time!

Step-by-step explanation:

In Mathematics, the order of operations (BOMDAS or BIDMAS) dictates that multiplication operations should be performed before addition. Hence, in the mathematical expression '80 + 80 equals 80 + 80 * 80 equals', the multiplication operation (80*80) is performed first, resulting in '80 + 6400 = 6480'. Therefore, 80 + 80 equals 6480.

In Mathematics, the operation order matters, this order is known by the acronym BOMDAS or BIDMAS, which stands for Brackets, Orders, Multiplication and Division, and Addition and Subtraction. it is used to clarify which procedures should be performed first in a given mathematical expression.

In your question, '80 + 80 equals 80 + 80 * 80 equals', we have both addition and multiplication operations. According to BIDMAS rules, we perform multiplication first before addition. Hence, the given expression is equivalent to 80 + 80 equals 80 + (80 * 80), where (80*80) should be calculated first.

Putting this into practice, we get: 80 + (80 * 80) = 80 + 6400 = 6480. Therefore, 80 + 80 equals 6480, based on the principles of BIDMAS or BOMDAS.

Answer:

50g/cm is equal to 5 kg/m

Step-by-step explanation:

as we know that:

10g/cm = 1 kg/m

so,

50g/cm = 5kg/m

The maximum number of parties the Center can host in a day is 12.

Given, the center is open for 11 hours each day and each party takes three hours. There are 4 rooms.

Therefore, 11 ÷ 3 = 3 (approx)

Each room can host 3 parties each day.

=3 × 4 = 12

The center can host up to 12 parties in a day.

Answer:

SORRY DONT KNOW

Step-by-step explanation:

the measure of angle ∠21 must be 55 degrees for line b to be parallel to line a.

In order for line b to be parallel to line a, the measure of angle ∠21  must be 125 degrees. Corresponding angles are angles that are in the same position relative to two intersecting lines. Since lines a and b are parallel, we know that corresponding angles ∠1 and ∠21 are congruent.  Therefore, we can set up the following equation to find the measure of ∠21:

∠1 + ∠21 = 180° (because they are supplementary angles)

Substituting 125° for the measure of ∠1, we get:

125° + ∠21 = 180°

Solving for ∠21, we get:

∠21 = 180° - 125°

∠21 = 55°

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Hello!

So, let's go over some information we know. We know that all the interior angles of a triangle add up to 180 degrees. We know that a line measures 180 degrees. We, therefore, know that angles which make up a line are supplementary, and must add up to 180 degrees.

So, first, we can find angle ABC. We can find this because angle ABC and ABT add up to 180 degrees, and we know the measure of ABT to be 125 degrees. Therefore:

ABC + 125 = 180

ABC = 55 degrees

Now, we can find angle ACB. We can find this as we have angle ABC and CAB, and angle ACB + ABC + CAB = 180 degrees (as they are the three interior angles of triangle ABC). ABC measures 55 degrees, and CAB 60 degrees. Therefore:

55 + 60 + ACB = 180

115 + ACB = 180

ACB = 65 degrees

Finally, we can find angle ACR based off of ACB, as ACB and ACR make up one line, and, therefore, add up to 180 degrees. ACB measures 65 degrees.

ACR + 65 = 180

ACR = 115 degrees

Therefore, your answer is choice 2, or 115 degrees.

Hope this helps!

Answer:

115°

Step-by-step explanation:

m∠ABC = 180° - 125° = 55° (angles in a straight line add up to 180°)

Given that m∠CAB = 60°,

Then m∠ACR = m∠CAB + m∠ABC (exterior angle is equal to the sum of opposite interior angles).

m∠ACR = 60° + 55° = 115°

Answer:

22.5 hours

Step-by-step explanation:

I am using "1 pond" to mean the volume of water that fits in the pond.

The inlet pipe fills the pond in 9 hours.

The filling rate is (1 pond)/(9 hours) = 1/9 pond/hour

The outlet pipe empties the pond in 15 hours.

The emptying rate is (1 pond)/(15 hours) = 1/15 pond per hour

The difference in rates is the net rate at which the pond is filling up.

1/9 pond/hour - 1/15 pond/hour =

= 5/45 pond/hour - 3/45 pond /hour

= 2/45 pond/hour

The pond is filling at a rate of 2/45 pond/hour.

To find the time it takes to fill the pond, we divide 1 pond by the rate.

(1 pond)/(2/45 pond/hour) = 45/2 hour = 22.5 hours

The number -5.41 can be classified as a Rational number because it can be expressed as a fraction where both the numerator (-541) and the denominator (100) are integers and it's not a whole number or an integer because it's negative and has a decimal part.

The number -5.41 is a type of number classified as a Rational number. Rational numbers are numbers that can be written as a fraction, where both the numerator and the denominator are integers (whole numbers), and the denominator is not zero. They can also be positive, negative, or zero, and they can be represented as decimals that terminate (like 0.2 or -1.75) or repeat (like 0.333... or -0.666...).

The number -5.41 is not a positive whole number nor an integer because it is negative and has a decimal part, which disqualifies it from both categories. An irrational number, on the other hand, is a number that cannot be expressed as a simple fraction, which clearly does not apply to -5.41 as it can be easily expressed by the fraction -541/100.
