–2.5p – 20 = 9p + 37.5

Mathematics

Sever21 [200]3 years ago

Answer:

The answer is p = -5

Step-by-step explanation:

-2.5p - 20 = 9p + 37.5

(move constants to one side by adding 20 to both sides)

-2.5p = 9p + 57.5

(move all terms with the "p" variable to one side by subtracting 9 from both sides)

-11.5p = 57.5

(divide both sides by -11.5 to isolate the variable)

p = -5

Answer:

p = - 5

Step-by-step explanation:

–2.5p – 20 = 9p + 37.5

combine like terms:

- 2.5p - 9p = 37.5 + 20

simplify:

- 11.5p = 57.5

p = 57.5 / -11.5

p = - 5

Answer:

230 - 151 + 180 + (43 - 12) = 290

Step-by-step explanation:

Use PEMDAS.

Evaluate the expression in the parentheses:

230 - 151 + 180 + (43 - 12)

43 - 12 = 31

230 - 151 + 180 + 31

Add and Subtract From Left to Right:

230 - 151 + 180 + 31

79 + 180 + 31

259 + 31

290

HELP ASAP!!! WILL MARK BRAINLIEST A proportional relationship between the number of pounds of potatoes (x) and the price in doll
Snezhnost [94]

Answer:

with proportional relationships, you can simply divide the y coordinate by the x coordinate to find the unit rate: In this case, if (5,4) lies on the line then you have 5 lbs of potatoes for 4 dollars or .80 cents for 1lb of potatoes. The point (10,8) represents 10 lbs of potatoes for 8 dollars. Here you can see that dividing 8 by 10 we once again get the unit rate of .80 cents per 1 lb of potatoes.

x = lbs of potatoes and y = price(4,3)....this means 4 lbs of potatoes cost $ 33/4 = 0.75 cents per lb <== 1 lb of potatoes cost 0.75(8,6)...this means that 8 lbs of potatoes cost $ 6

Hope this helps

Create a system of linear equations that has one solution. Solve the system using substitution to prove your
bezimeni [28]

Answer:

y = -2x + 3

y = -1/2x + 5

Step-by-step explanation:

  • So the best way to solve is to come up with two slopes, I'd prefer 2 perpendicular slopes because perpendicular lines only cross once hence one solution guaranteed
  • so say we choose a slopeA = 2 and slopeB = -1/2, the slopes are perpendicular only if when you multiply them you get -1
  • then we use the slope intercept form of an equation y = mx + b
  • we make up two equations y = -2x + b and y = -1/2x + b , now we can just make up number for b so the two equations are
  • y = -2x + 3
  • y = -1/2x + 5
  • Then we solve them by substituting for y so
  • -1/2x + 5 = -2x + 3 and x = -4/3
  • and then we put this to get y in either equation
  • y = -2(-4/3) + 3
  • y = 17/3
  • So the equations work
