write a phrase to represent each algebraic expression
2x-9
2(x-9)​

Answer:

So, you just end up plugging in your numbers.

y = 28 - 3(1)

y = 28-3

y = 25

Y = 28 - 3(3)

y = 28 - 9

y = 19

y = 28 - 3x

y = 28 - 3(4)

y = 28 - 12

y = 16

y = 28 - 3x

y = 28 - 3(6)

y = 28 - 18

y = 10

Step-by-step explanation:

The completed table is:

X   Y

1   25

3   19

4   16

6   10

To fill in the table using the function rule y = 28 - 3x, we can substitute the given values of x into the equation to find the corresponding values of y.

X Y

1 28 - 3(1) = 28 - 3 = 25

3 28 - 3(3) = 28 - 9 = 19

4 28 - 3(4) = 28 - 12 = 16

6 28 - 3(6) = 28 - 18 = 10

So, the completed table is:

X Y

1 25

3 19

4 16

6 10

For each value of x, we substituted it into the function rule and performed the necessary calculations to determine the corresponding value of y.

Answer: 11/24

Step-by-step explanation:

5/6 - 3/8 = 11/24

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

Answer:

27,9

Step-by-step explanation:

9x3=27

To do such problems we need to know the concept of multiple of a number.

A multiple is a number that is the result of multiplying a number by an integer (not a fraction).

Given options,

a.)  27, 9

We can write 27 as 9 x 3, therefore, we can see that 27 is a multiple of 9.

b.)  25, 6

We can write 25 as 5 x 5, we can see that 25 is not a multiple of 6.

c.) 8, 72

We can write 8 as 2 x 2 x 2, we can see that 8 is not a multiple of 72.

d.)  52, 3

We can write 52 as 2 x 2 x 13, we can see that 52 is not a multiple of 3.

Answer:

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:

- 6.2

Step-by-step explanation:

The product of - 2 (3.1) is - 6.2.

Brackets mean to multiply so we have to multiply the - 2 by 3.1 which gives a result of - 6.2.

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.

x= -30/-15 = 2

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:3.9

Step-by-step explanation:

Answer: 25 x 3 divided by 19 is 3.94736842105

Answer:

m<AFE​ =  128°.

Step-by-step explanation:

Step 1: Find the value of x

Angle EFD + Angle DFC = Angle EFC

5x + 6 + 19x - 15 = 17x + 19

24x - 9 = 17x + 19

7x = 28

x = 4

Step 2: Find all angles

Angle AFB=Angle EFD= 5x + 6

5(4) + 6 = 26°

Angle DFC = 19x - 15

19(4) - 15 = 61°

Step 3: Find angle AFE

Line BD is a straight line and all angles on a straight line are equal to 180°.

Angle AFB + Angle AFE + Angle EFD = 180°

26 + BFC + 26 = 180°

BFC = 180 - 52

BFC = 128°

Therefore, m<AFE​ is equal to 128°.

!!

The measure of m<AFE  if m<EFD = (5x+6)°, m<DFC = (19x-15)°, and m<EFC = (17x+19)° is 128degrees

Angle is the point where two or more lines meet. From the given diagram:

m<EFC = m<EFD + m<DFC

Given the following:

m<EFC = 17x + 19

m<EFD = 5x+6

m<DFC = 19x - 15

Substitute the given values into the expression

17x + 19 = 5x + 6 + 19x - 15

17x - 5x - 19x = -19 - 9

12x - 19x = -28

-7x = - 28

x = 28/7

x= 4

Get the angle m<AFE

m<AFE  + m<ABF + m<EFD = 180

Since  <AFB = <EFD

m<AFE  + m<EFD + m<EFD = 180

m<AFE + 2m<EFD = 180

m<AFE + 2(5x+6) = 180

m<AFE + 2(5(4) + 6) = 180

m<AFE +2(26) = 180

m<AFE + 52 = 180

m<AFE = 180 - 52

m<AFE = 128 degrees

Hence the measure of m<AFE is 128degrees

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
