An is a mathematical statement that shows two expressions are equal using an equal sign.

Ok so what you need to do is you need to get all the numbers and see which one is the right number so...

A. y = 11.2 that is wrong

B. y = 25 is wrong

C. y = 5 is right

D. y = 15 is wrong.

C is right because it would be 5 times 5 times 5. SO 5 times 5 is 25, and then u times it by 5 and you get 125!

C is correct

Hope this helps!!

Answer:

This is actually a cube root, since you need a cube root to cancel out the cube.

C, y = 5

Step-by-step explanation:

125 = 5 × 5 × 5 = 5^3

5 × 5 × 5 = 25 × 5 = 125.

Therefore the cube root of 125 = 5.

It REALLY helps when you break these into factors.

[tex] \sqrt[3]{125} = 5 , \: as \: {5}^{3} \: = 125 [/tex]

This is essentially asking what multiplied by itself three times is equal to 125.

Process of elimination can be used for any number cubed that is ≠ 125

i.e : 11.2^3 ≠ 125

11.2^3 = 11.2 × 11.2 × 11.2 = (11.2-1.2)(11.2+1.2)(11.2) = (11.2)((10)(12.4) + 1.2^2) = 124 + 1.44 = (125.44)(11.2) = 125.44(10+1+(2/10)) = 1254.4 + 125.44 + 25.088 = 1404.928 ≠ 125, y ≠ 11.2

I.e : 25^3 = 25 × 25 × 25 = 625 × 25 = (600+25)(25) = 625 + 6(25)(100) = 15000 + 625 = 15625 ≠ 125, y ≠ 25.

And i.e: 15^3 = 15 × 15 × 15 = 225 × 15 = (225)(10+5) = 225(10) + 225(10/2) = 2250 + 2250/2 = 2250 + 1125 = 3375 ≠ 125, y ≠ 15.

Answer:

tn=9+3(n-1)

Step-by-step explanation:

Formula: tn=t1+d(n-1)

AKA: term n=term 1 plus common difference times n minus 1

For this sequence: tn=tn; t1=9; common difference=3; n-1=n-1

Plug in the answer: tn=9+3(n-1)

45x6=270.270 is the total for the friends.However instead you have to do 45x7=315.Because its Leahs friends and LEAH.So now the car.315+10=325.So your answer is 325

Step-by-step explanation:

-2 = y + 5

- y -2 = 5

- y = 5 + 2

- y = 7

y = -7

-2x + 3x – 5 = 6 – 21

x – 5 = 6 – 21

x – 5 = -15

x = -15 + 5

x = -10

70 = 7m

7m = 70

m = 10

4 – 14 = 5x

-10 = 5x

5x = -10

x = -2

2y + 3y = 4 – 6 – 13

5y = 4 – 6 – 13

5y = -15

y = -3

Answer:

x=7

Step-by-step explanation:

first, add 12 to both sides so it would look like: 6x-12+12=30+12

so, ya get 6x=42

then you divide 6 from both sides, and that is: 6x/6=42/6

so x=7

Step-by-step explanation:

let the other leg be x

Then using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 3² = 4²

x² + 9 = 16 ( subtract 9 from both sides )

x² = 7 ( take the square root of both sides )

x = 7

Answer:

144

Step-by-step explanation:

Since a is 6 and b is 24 we would have to multiply both of those numbers which would give you 144.

Hope this helps and good luck!!

When a = 6 and b = 24, the value of the equation ab will be 144.

Algebra is the study of mathematical symbols, while logic is the manipulation of those signifiers.

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction is referred to as the PEMDAS rule. To answer the problem properly and accurately, this rule should be followed.

The expression is given below.

⇒ ab

If the values of "a" and "b" are 6 and 24, respectively. The expression's value is then provided as,

⇒ a × b

⇒ 6 × 24

⇒ 144

When a = 6 and b = 24, the value of the equation ab will be 144.

Answer:

74 adult tickets and 106 children tickets

Step-by-step explanation:

let x be the number of adults tickets sold out

and y the number of chlidrens tickets that sold out for the 7:15 pm show

The equations that determine our problem are

x+y=180

12.50x+8.50y=1826

lets separate x from first equation x=180-y and replace at the second equation

12.50(180-y)+8.50y=1826

12.50*180-12.50y+8.50y=1826

2250-4y=1826

4y=2250-1826

y=424/4=106

so x=180-y=180-106=74

Answer:9

Step-by-step explanation:

Answer:

number of large year book sold = 380

number of small year book sold =520

Step-by-step explanation:

Let the no. of large year book pages be x

given that

cost of 1 large year book = $4

cost of x large year book = x*cost of 1 large year book = $4x

Let the no. of small year book pages be y

given that

cost of 1 small year book = $2.5

cost of y small year book = y*cost of 1 large year book = $2.5y

also,

total year books sold were 900

no. of small year book + no. of small year book = 900

x + y = 900

y = 900 - x  ------------------>1

also total money made by selling large and small year book = $2820

cost of x small year book + cost of x large year book = 2820

4x + 2.5y = 2820

using y = 900 - x in above equation

4x + 2.5(900-x) = 2820

4x + 2250 - 2.5x = 2820

1.5x = 2820-2250 = 570

x = 570/1.5 = 380

Thus,

number of large year book sold = 380

number of small year book sold = 900-380 = 520
