0.2x-8=0.4x-7
What is x?

so 75%of 20 is 15.00

and then we 20.00+15.00= 35.00

plus sales tax of 5%

so I got 36.75$ after taxs

Answer:

The second option

Step-by-step explanation:

First, simplify the bracket

[tex] \frac{4r {}^{3} s {}^{2} t {}^{4} }{2r {}^{4} st {}^{6} } [/tex]

Apply Quotient of Powers

[tex]2 {r}^{ - 1} s {t}^{ - 2} [/tex]

Which equals

[tex] \frac{2s}{rt {}^{2} } [/tex]

Raise this to the fifth power

[tex] \frac{32s {}^{5} }{ {r}^{5} t {}^{10} } [/tex]

Multiply by the outsides numbers(5^r^6 and t^4

[tex] \frac{160 {}^{} r {}^{6}s {}^{5} t {}^{4} }{r {}^{5} t {}^{10} } [/tex]

[tex]160r {}^{5} t {}^{ - 6} [/tex]

[tex] \frac{160r {}^{}s {}^{5} }{t {}^{6} } [/tex]

Answer:

B=107

Step-by-step explanation:

Foremost, D and B are equal measure which can be shown by proving that these two triangles are congruent. A+C+D=180, D=180-(32+41)=107

Big Mac has 550 calories

Chicken Nugget has 275 calories

Grilled Chicken Sandwich has 350 calories

Total number of calories = 1175

Let the number of calories in Big Mac = x

Since the 6-piece chicken nugget meal has half the calories of the Big Mac. Therefore, the number of calories in the chicken nugget = 1/2 × x = 0.5x

Since the Grilled Chicken Sandwich has 200 less calories than the Big Mac.  This will be: = x - 200

To calculate the number of calories in each food goes thus:

x + 0.5x + x - 200 = 1175

Collect like terms

x + 0.5x + x = 1175 + 200

2.5x = 1375

Divide by 2.5

2.5x/2.5 = 1375/2.5

x = 550

Big Mac has 550 calories

Chicken nugget will have:

= 0.5x = 0.5 × 550 = 275 calories

Grilled Chicken Sandwich will be:

= x - 200

= 550 - 200

= 350 calories

-4.

Step-by-step explanation:

There are 31 days in August.

1/2 * 31 - 1/2 * 39

= 15 1/2 - 19 1/2

= -4.

Answer:

Most likely yes... there is a problem in the way you asked your question ...

if the question is   [tex]y = ( \frac{-4}{5}) x[/tex] then the answer is yes and the constant is -4/5's

If by some chance the actual question is   [tex]y = \frac{-4}{(5x)}[/tex] (you can not tell by the way y0u presented tis problem.. then the answer would be NO it would be "inverse" relation

Step-by-step explanation:

Answer:

H) B= 13

Step-by-step explanation:

5 + b = 18

F) 5 + 5 = 10 so not equal to 18. It is not a solution

H) 5 + 13 = 18 it's equal . so it is the solution

G) 5 + 8 = 13  so not equal to 18. It is not a solution

J)  5 + 23 = 28  so not equal to 18. It is not a solution

13 is the answer

Step-by-step explanation:

5+b=18

b=18-5

b=13.

Answer:

Step-by-step explanation:

For a. the 14.7 represents the pressure that the air puts on you all the time.

For b. the d represents the depth you go under the surface of the water.

For c. we have to solve p(d) when d = 8:

p(8) = 14.7 + 0.445(8) so

p(8) = 14.7 + 3.56 and

p(8) = 18.26 psi

Answer: 76 mph

Step-by-step explanation: speed is distance divided by time so 475 : 6.25 = 76 (mph)

Answer:

76 mph

Step-by-step explanation:

To find the answer, you would divide the miles she drove: 475 by the amount of time it took to get there: 6 1/4 hours. Convert the fraction to a decimal: 1/4= .25 so your problem would look like this...

475 / 6.25 = 76
