Answer:
x = -5
Step-by-step explanation:
0.2x-8=0.4x-7
First, add 8 to both sides.
0.2x-8+8=0.4x-7+8
0.2x=0.4x-1
Next, subtract 0.4x from both sides.
0.2x-0.4x=0.4x-1-0.4x
-0.2x=1
Divide both sides by -0.2:
-0.2x/-0.2=1/-0.2
x=-5

There are 1175 calories total in a Big Mac, a Grilled Chicken Sandwich and a 6-piece chicken nugget meal.
A 6-piece chicken nugget meal has half the calories of the Big Mac. The Grilled Chicken Sandwich has 200 less
calories than the Big Mac. How many calories are in each of the three food items?
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

F b= 5
H b= 13
Gb=8
Jb= 23
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:

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:
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

What was Veronica's speed if she drove 475 miles in 6 1/4 hours?
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
