Answer:

n = 1

Step-by-step explanation:

So the first step is to simplify the top equation:

(3v + 7) - (8v + 6)

distribute the negative sign to get rid of the second parentheses:

3v + 7 - 8v - 6

now, combine like terms

-5v + 1

Since it says it needs to be equivalent to (-5v + n), n is 1

2/9

Step-by-step explanation:

log2x = 1 - log(x+4)

log2x = log10 - log(x+4)

log2x = log[10/(x+4)]

2x = 10/(x+4)

2x(x+4) = 10

2x² + 8x - 10 = 0

÷2 both sides of equation

x² + 4x - 5 = 0

(x+5)(x-1) = 0

x = -5, 1

x isn't be -5 because logA, A need to be > 0

So, x value is 1

Answer:

$4.80

Step-by-step explanation:

$32 × 0.15 = $4.80

Answer:

Frequently, we know the new amount and the percent change and need to know the original amount. We found that a $600 TV on sale for 30% off, cost $420 on sale. We might think, that to find the original cost of the TV that has a sale price of $420 after a sale of 30% off, we could just take 30% of the $420 cost and add it back to the $420 to find the original cost.

30% of $420 is 0.30($420) = $126 and $420 + $126 = $546.

Or, 130% of $420 is 1.3($420) = $546.

Notice that this is not the $600 original list price with which we started.

Answer:

-2/3 is the right answer

Answer:

the simplified version of 3/9 would be 1/3 but other equivalent fractions of 3/9 would include but are not exclusive to: 2/6, 4/12, 5/15, and etc.

The required fraction 3/9 is equivalent to 1/3.

Given that the fraction is 3/9.

Equivalent fractions are the fractions are same at their simplest form.

Let a/b be the fraction, then the equivalent fractions are

2a/2b, 3a/3b, 4a/4b, 5a/5b,   etc

To find an equivalent fraction, we simplify the given fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).

In this case, the GCD of 3 and 9 is 3.

Dividing both 3 and 9 by 3, we get:

3 ÷ 3 = 1

9 ÷ 3 = 3

Therefore, the fraction 3/9 simplifies to 1/3, which is an equivalent fraction.

Answer:

16%

Step-by-step explanation:

To calculate this we first need to calculate the probability of Mario scoring for every individual shot that he takes. Since he makes 2 goals for every 5 shots on average, we simply divide these numbers to get the probability of a goal per shot.

2 / 5 = 0.4  ...multiply by 100 to get percentage value

0.40 * 100 = 40%

We see that the probability of scoring a goal per shot is 40%. Now we need to multiply this probability twice to get the probability of scoring 2 consecutive goals in two shots.

0.40 * 0.40 = 0.16  ... multiply by 100 to get percentage value

0.16 * 100 = 16%

Answer:

16%

Step-by-step explanation:

I know that 2/5 = 0.4 or 40%

and 0.4 x 0.4 = 0.16

or 16%

Answer:

x = - 3 and x = 1

Step-by-step explanation:

4x - 2 - 2x = x - 5, that is

2x - 2 = x - 5 ( subtract x from both sides )

x - 2 = - 5 ( add 2 to both sides )

x = - 3

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

- (x + 3) = 2x - 6 ← distribute left side

- x - 3 = 2x - 6 ( subtract 2x from both sides )

- 3x - 3 = - 6 ( add 3 to both sides )

- 3x = - 3 ( divide both sides by - 3 )

x = 1

Given:

The length of a rectangle is 3 inches less than three times its width.

The perimeter of the rectangle is 34 inches.

To find:

The dimensions of the rectangle.

Solution:

Let x be the width of the rectangle. Then, the length of a rectangle is 3 inches less than three times its width.

Length of the rectangle = 3x-3

Now, perimeter of the rectangle is

[tex]Perimeter=2(Length + Width)[/tex]

[tex]Perimeter=2(3x-3+x)[/tex]

The perimeter of the rectangle is 34 inches.

[tex]34=2(4x-3)[/tex]

[tex]34=8x-6[/tex]

[tex]34+6=8x[/tex]

[tex]40=8x[/tex]

Divide both sides by 8.

[tex]\dfrac{40}{8}=x[/tex]

[tex]5=x[/tex]

The value of x is 5. So, width of the rectangle is 5 inches.

[tex]Length=3x-3[/tex]

[tex]Length=3(5)-3[/tex]

[tex]Length=15-3[/tex]

[tex]Length=12[/tex]

Therefore, the length of the rectangle is 12 inches and the width of the rectangle is 5 inches.
