Answer:

each football cost $15.75

Step-by-step explanation:

Micheal bought 3 footballs with a $50 bill.

The cashier gave him $2.75 in change.

Each football cost the same amount

$50 - $2.75 = $47.25

$47.25  =  $15.75

3 balls

therefore, each football cost $15.75

Answer:

[tex] x = 9 [/tex]

Step-by-step explanation:

Given:

[tex] PQ = x - 5 [/tex]

[tex] QR = 2x - 1 [/tex]

[tex] PR = 21 [/tex]

Required:

Value of x

SOLUTION:

Point P, Q, and R are collinear, therefore:

[tex] PQ + QR = PR [/tex] (segment addition postulate)

[tex] (x - 5) + (2x - 1) = 21 [/tex] (substitution)

Solve for the value of x using the above equation.

[tex] x - 5 + 2x - 1 = 21 [/tex]

Combine like terms

[tex] x + 2x - 5 - 1 = 21 [/tex]

[tex] 3x - 6 = 21 [/tex]

Add 6 to each side of the equation

[tex] 3x - 6 + 6 = 21 + 6 [/tex]

[tex] 3x = 27 [/tex]

Divide each side by 3

[tex] \frac{3x}{3} = \frac{27}{3} [/tex]

[tex] x = 9 [/tex]

Answer:

9

Step-by-step explanation:

Let the two perfect cubes be x and y where x > y.

According to the given conditions:

[tex] {x}^{3} - {y}^{3} = 386...(1) \\ y = 7...(2) \\ plug \: y = 7 \: in \: equation \: (1) \\ {x}^{3} - {7}^{3} = 386 \\ {x}^{3} - 343 = 386 \\ {x}^{3} = 343 + 386 \\ {x}^{3} = 343 + 386 \\ {x}^{3} = 729 \\ x = \sqrt[3]{729} \\ x = 9[/tex]

Thus the cube root of the larger number is 9.

Building and solving an equation, it is found that the cube root of the larger number is 9.

-------------------------

[tex]x^3 - y^3 = 386[/tex]

[tex]x^3 - y^3 = 386[/tex]

[tex]x^3 - 7^3 = 386[/tex]

[tex]x^3 - 343 = 386[/tex]

[tex]x^3 = 386 + 343[/tex]

[tex]x^3 = 729[/tex]

[tex]x = \sqrt[3]{729}[/tex]

[tex]x = 9[/tex]

Thus, the cube root of the larger number is 9.

Answer: 15b+4=25 & 15b=21

Step-by-step explanation:0.6+15b+4=25.6

0.6+4= 4.6 , 4.6+15b=25.6 Subtract from both sides 25.6-4.6= 21 4.6-4.6=0 bring down 15b Now do 21÷15b= 1.4 . So now we know b represent 1.4. 15b+4=25 Subtract 4 from both sides 25-4=21 4-4=0 There's nothing left on that side but 15b so bring down 15b in order to get rid of your variable divide it 21÷15= 1.4 On this one b also represents 1.4 . 15b=21 this equation do not have an number so just divide 21 by 15 to get rid of your variable which equals 1.4 In this equation b= 1.4 So these to equations are equivalent which is another word for equal.

The equations which are equivalent to 0.6 + 15b + 4 = 25.6.

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in maths when you do not know the exact number in a calculation.

Given:

0.6 + 15b + 4 = 25.6.

On solving it further

15b + 4= 25.6-0.6

15b+4=25

15b= 25-4

15b= 21

3(0.6 + 15b + 4) = 76.8

On solving

0.6 + 15b + 4 = 76.8/3

0.6 + 15b + 4 = 25.6

So, the equivalent equations are:

Answer:

the last bubble

Step-by-step explanation:

Perpendicular lines have opposite reciprocal slopes

the original line: y = 5/2x + 5

The perpendicular line: y = -2/5x + b

To find b, we have to plug (-10, 5) into x and y for our perpendicular line

5 = -2/5(-10) + b

Simplify the right side

5 = 4 + b

Subtract 4 from both sides

1 = b

The final answer = y = -2/5x + 1

Answer:

a = cd + b / b

Explanation:

ba − cd = b

[ Step 1: Add cd to both sides ]

ab − cd + cd = b + cd

ab = cd + b

[ Step 2: Divide both sides by b ]

ab / b = cd + b / b

a = cd + b / b

Answer:

x = 2 log 2 / (log 5 − log 2)

x = log 4 / log(2.5)

Step-by-step explanation:

2ˣ⁺² = 5ˣ

Take log of both sides.

log(2ˣ⁺²) = log(5ˣ)

Use exponent property.

(x + 2) log 2 = x log 5

Distribute.

x log 2 + 2 log 2 = x log 5

Subtract x log 2 from both sides.

2 log 2 = x log 5 − x log 2

Factor out x.

2 log 2 = x (log 5 − log 2)

Solve for x.

x = 2 log 2 / (log 5 − log 2)

If you want, you can simplify further:

x = log 4 / log(2.5)

Let's plug in x = 2.

f(x) = x^2

f(2) = 2^2 ... replace every x with 2

f(2) = 4

----------

Now plug in x = 3.

f(x) = x^2

f(3) = 3^2 ... replace every x with 3

f(3) = 9

-----------

And x = 5 as well.

f(x) = x^2

f(5) = 5^2 .... replace every x with 5

f(5) = 25

-----------

We see that

f(2)+f(3) = 4+9 = 13

which is not equal to f(5) = 25.

So f(2)+f(3) = f(5) is false.

------------

Another way to phrase why it doesn't work is because (2,3,5) isn't a pythagorean triple. The equation 2^2+3^2 = 5^2 is false.

If it said f(3)+f(4) = f(5), then it would be correct because 3^2+4^2 = 5^2 is a true equation.

Answer:

Yes.

Step-by-step explanation:

Rational numbers can be represented as fractions with integers. The denominator must not equal 0.

[tex]\frac{7}{9}[/tex] is already in this form. This means that it's a rational number.

Hope this helps.

Yes, 7/9 is a rational number. A rational number is any number that can be expressed as a fraction of two integers, where the denominator is not zero.

In this case, 7/9 can be written as the fraction where the numerator (7) and denominator (9) are both integers. Since there is no division by zero, 7/9 qualifies as a rational number.

Rational numbers can be represented as terminating decimals or repeating decimals. When we divide 7 by 9, we get the decimal representation 0.777... where the digit 7 repeats infinitely. This is a repeating decimal, and it's still considered rational because it can be expressed as the fraction 7/9.

In conclusion, 7/9 is a rational number since it can be expressed as the fraction of two integers, and it can be represented as a repeating decimal.
