The original price of the car stereo before any discounts or taxes was approximately $187.14.

We have,

Gina paid $131 for the car stereo after it was discounted by 30%.

Let's represent the original price of the stereo as "x" dollars.

The discounted price would be 70% (100% - 30%) of the original price:

Discounted price = 0.70 * x

Given that Gina paid $131, we can set up the equation:

0.70 * x = 131

Now, solve for "x" by dividing both sides of the expression by 0.70:

x = 131 / 0.70

x ≈ 187.14

So, the original price of the stereo before the discount was approximately $187.14.

There was also 7% sales tax on the purchase.

To find the sales tax amount, we calculate 7% of the original price:

Sales tax = 0.07 * 187.14 ≈ 13.10

Now, to find the total original cost before the sales tax, we add the original price and the sales tax:

Total original cost = Original price + Sales tax

Total original cost ≈ 187.14 + 13.10 ≈ 200.24

Therefore,

The original price of the car stereo before any discounts or taxes was approximately $187.14.

Step-by-step explanation:

2a^2+5/7+b

a= -6

b= -2

solution

2(-6 x -6 )+5/7 +-2

2(36)+5/7+( -2 )

2x36=72

so it will be

72+5/7+ (-2)

72+5=77

77/7+(-2)

= 11+(-2)

9 is the answer.

Answer:

$43.75

Step-by-step explanation:

(35/8)x10=43.75

Answer:

Yes this statement is true because 0/3 is 0

Answer:

False.

Step-by-step explanation:

x = 0 would be the only solution to make the statement true. Anything other than x = 0 will make the statement false.

First, let's create two variables to express the girls' ages.

x=age of girl 1

y = age of girl 2

Now, let's create our expressions

x+y = 24

x-y=6

Let's solve by elimination

2x = 30

Divide both sides by 2

x=15

We can plug 15 in for x into one of our expressions

15 + y = 24

Subtract both sides by 15

y = 9

The older girl is 15 years old and the younger girl is 9 years old.

Yes

Step-by-step explanation:

[tex] \frac{16}{24} = \frac{2}{3} [/tex]

if we divide 16 ÷ 8 = 2

if we divide 24 ÷ 8 = 3

[tex] \frac{28}{42} = \frac{4}{6} = \frac{2}{ 3} [/tex]

if we divide 28 ÷ 7 = 4

if we divide 42 ÷7 = 6

we divide both 6 and 4 ÷2

2/3

[tex] \frac{16}{24} = \frac{28}{42} [/tex]

Answer:

(3a + b) : (4a +2b) = 5 : 8

Step-by-step explanation:

For:

[tex]a : b = 1 : 2[/tex]

Express these ratios into fractions:

[tex] \frac{a}{b} = \frac{1}{2} [/tex]

Simplify:

[tex]2a = b - - - \{eqn \: (n) \}[/tex]

For:

[tex](3a + b) : (4a +2 b)[/tex]

Express into fractions:

[tex] = \frac{(3a + b)}{(4a + 2b)} \\ [/tex]

substitute for b as 2a from equation (n):

The distance between the pair of points is 12.0 (to the nearest tenth)

Step-by-step explanation:

The distance between a pair of points in a coordinate system is found by the formula:

d =[tex]\sqrt({x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where, the points are:

[tex](x_1,y_1)\ and\ (x_2,y_2)[/tex]

From the graph,

[tex](x_1,y_1)=(-6,-2)\\(x_2,y_2)=(2,7)[/tex]

Substitute the points into the formula:

[tex]d=\sqrt{(2-(-6)^2+(7-(-2)^2} \\d=\sqrt{(2+6)^2+(7+2)^2} \\d=\sqrt{8^2+9^2} \\d=\sqrt{64+81} \\d=\sqrt{145} \\\d=12.0[/tex]

Answer:

  t = 4

Step-by-step explanation:

It can be useful to convert the numbers to ratios of integers.

  0.0625 = (0.5)^t

  1/16 = (1/2)^t

  1/2^4 = 1/2^t

  4 = t . . . . . . . match exponents

__

If you like, you can solve this using logarithms.

  0.0625 = 0.5^t

  log(0.0625) = t×log(0.5)

  t = log(0.0625)/log(0.5)

  t = 4
