How to solve a coefficient

Answer:

3 (m^2 - 16)

Step-by-step explanation:

factoring means taking out a common multiple of all the terms in the expression

in this case, if you multiply 3 and m^2, 3 and -16, you would get 3m^2-48​

so you take the three and put it outside of the parenthesis that contains the factored terms

this leaves you with 3 (m^2 - 16)

Answer:

b. 5x + 4y = 80

Step-by-step explanation:

Let us assume the remaining balance left be Y

and, the number of songs purchased be X

Given that

Wins a gift card of $20

And, the songs purchased is 16

Now if we take the fraction

= 20 ÷ 16

= 5 ÷ 4

So if we reverse this fraction

So it could be 5x and 4y

And, the amount that would come is

= $20 × 16 ÷ 4

= 80

So, the equation is 5x + 4y = 80

Hence, the correct option is b.

Answer:

[tex]P(x)=(x-2i)(x-3i)[/tex]

Step-by-step explanation:

Build a Polynomial Knowing its Roots

If we know a polynomial has roots x1, x2, ..., xn, then it can be expressed as:

[tex]P(x)=a(x-x1)(x-x2)...(x-xn)[/tex]

Where a is the leading coefficient.

Note the roots appear with their signs changed in the polynomial.

If the polynomial has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1, then:

[tex]P(x)=1(x-2i)(x-3i)[/tex]

[tex]\mathbf{P(x)=(x-2i)(x-3i)}[/tex]

Given:

Initial amount = $8600

The amount in the account had decreased by 23.5%.

To find:

Decrease in amount and amount at the end of last year.

Solution:

The amount in the account had decreased by 23.5%. So,

Decreased amount = 23.5% of 8600

[tex]=\dfrac{23.5}{100}\times 8600[/tex]

[tex]=23.5\times 86[/tex]

[tex]=2021[/tex]

Now, the amount at the end of the last year is

Amount = Initial value - Decreased value

[tex]Amount=8600-2021[/tex]

[tex]Amount=6579[/tex]

Therefore, the decreased value is $2021 and the amount at the end of last year is $6579.

Answer:

t = 4

Step-by-step explanation:

Solve for t:

8 - (7 t)/10 = 6 - t/5

Hint: | Put the fractions in 8 - (7 t)/10 over a common denominator.

Put each term in 8 - (7 t)/10 over the common denominator 10: 8 - (7 t)/10 = 80/10 - (7 t)/10:

80/10 - (7 t)/10 = 6 - t/5

Hint: | Combine 80/10 - (7 t)/10 into a single fraction.

80/10 - (7 t)/10 = (80 - 7 t)/10:

1/10 (80 - 7 t) = 6 - t/5

Hint: | Put the fractions in 6 - t/5 over a common denominator.

Put each term in 6 - t/5 over the common denominator 5: 6 - t/5 = 30/5 - t/5:

(80 - 7 t)/10 = 30/5 - t/5

Hint: | Combine 30/5 - t/5 into a single fraction.

30/5 - t/5 = (30 - t)/5:

(80 - 7 t)/10 = (30 - t)/5

Hint: | Make (80 - 7 t)/10 = (30 - t)/5 simpler by multiplying both sides by a constant.

Multiply both sides by 10:

(10 (80 - 7 t))/10 = (10 (30 - t))/5

Hint: | Cancel common terms in the numerator and denominator of (10 (80 - 7 t))/10.

(10 (80 - 7 t))/10 = 10/10×(80 - 7 t) = 80 - 7 t:

80 - 7 t = (10 (30 - t))/5

Hint: | In (10 (30 - t))/5, divide 10 in the numerator by 5 in the denominator.

10/5 = (5×2)/5 = 2:

80 - 7 t = 2 (30 - t)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the right hand side:

80 - 7 t = 60 - 2 t

Hint: | Move terms with t to the left hand side.

Add 2 t to both sides:

2 t - 7 t + 80 = (2 t - 2 t) + 60

Hint: | Look for the difference of two identical terms.

2 t - 2 t = 0:

2 t - 7 t + 80 = 60

Hint: | Group like terms in 2 t - 7 t + 80.

Grouping like terms, 2 t - 7 t + 80 = 80 + (2 t - 7 t):

80 + (2 t - 7 t) = 60

Hint: | Combine like terms in 2 t - 7 t.

2 t - 7 t = -5 t:

-5 t + 80 = 60

Hint: | Isolate terms with t to the left hand side.

Subtract 80 from both sides:

(80 - 80) - 5 t = 60 - 80

Hint: | Look for the difference of two identical terms.

80 - 80 = 0:

-5 t = 60 - 80

Hint: | Evaluate 60 - 80.

60 - 80 = -20:

-5 t = -20

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -5 t = -20 by -5:

(-5 t)/(-5) = (-20)/(-5)

Hint: | Any nonzero number divided by itself is one.

(-5)/(-5) = 1:

t = (-20)/(-5)

Hint: | Reduce (-20)/(-5) to lowest terms. Start by finding the GCD of -20 and -5.

The gcd of -20 and -5 is -5, so (-20)/(-5) = (-5×4)/(-5×1) = (-5)/(-5)×4 = 4:

Answer: t = 4

Answer:

0 = 7m

0 = m

m = 0

It is 0 because first you would have to cancel -10 on both of the sides then divide both of the sides by 7 then switch the sides which is 0

The result of the equation -10 = -10 + 7m is m = 0

The given equation is:

-10  =  -10   +  7m

Add 10 to both sides of the equation

-10  +  10   =  -10  +  10  +  7m

0   =   7m

Rewrite the equation as:

7m   =  0

Divide both sides of the equation

7m/7   =  0/7

m  =  0

This is because 0 divided by any number is 0

Therefore, the result of the equation -10 = -10 + 7m is m = 0

Answer:

If the perimeter is 200feet (two lengths and two widths) then one width+one length equals 100feet.

If the length is 10 feet longer than the width, then length = 55 feet, and width =45 feet

Therefore the area of the rectangle is 45x55 feet, which equals 2475 sq.ft

Step-by-step explanation:

Let the shortest side of the triangle be 5x, the middle side be 6x, and the longest side be 8x.

5x+6x+8x = 159.6

19x = 159.6

x = 159.6 ÷ 19

x = 8.4

Shortest side of triangle (5x) = 8.4 × 5
