Answer:

32n = 100 - 20

n = 2.5

he purchased 2 sweaters

Step-by-step explanation:

32n = 100 - 20

If Favian originally had $100 but spent $20 on a belt, he only had 80 left, meaning that 80 = 32n which means that he was able to but 2 sweaters and got $16 back. Therefore the formula would be 32n = 100 - 20

The formula for the number of sweaters will be 32n = 100 – 20.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Favian received a $100 gift card to a clothing store.

Using only the gift card, he was able to purchase n sweaters that cost $32 each and 1 belt for $20.

If there was no tax on the sweaters and belt,

Then the equation will be

32n + 1 x 20 = 100

    32n + 20 = 100

             32n = 80

                 n = 2.5 ≈ 2

If Favian originally had $100 but spent $20 on a belt, he only had 80 left, meaning that 80 = 32n, which means that he was able to but 2 sweaters and got $16 back.

Therefore, the formula would be 32n = 100 – 20.

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

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:

80%

Step-by-step explanation:

4 divided by 5 = 0.8

0.8 x 100 = 80%

The percentage Larry ran around the track = 80%  

He ran 4/5 of the way around the track before slowing down for a walk.

This means he ran 4 parts of the whole 5 parts of the track. He walks the remaining 1 part around the track.

Therefore, the percentage he ran can be calculated below

% he ran the track = 4 / 5 of 100

% he ran the track = 4 / 5 × 100 = 400 / 5 =  80%

The percentage he ran around the track  = 80%

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)

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:

- 340

Step-by-step explanation:

The sum to n terms of an AP is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] ( a + l ) → a is the first term and l the last term

Here a = - 76 and [tex]S_{45}[/tex] = - 9360 , thus

[tex]\frac{45}{2}[/tex] ( - 76 + l ) = - 9360

22.5(- 76 + l) = - 9360 ( divide both sides by 22.5 )

- 76 + l = - 416 ( add 76 to both sides )

l = - 340 ← the last term in the sequence

Answer:  True

Step-by-step explanation:

quantative is numbers and stats

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: 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
