Mathematics

frez [133]4 years ago

Answer:

Write the equation as n + 31 = 113 and subtract 31 from both sides. The answer is 82.

Step-by-step explanation:

The sum of a number and 31 would be 'n + 31'. The sum equaling 113 would be '= 113'.

You would get 'n' by subtracting 31 for each side.

n+31 = 113\\n+31-31=113-31 \leftarrow \text{Subtraction Property of Equality} \\\boxed{n=82}

The statement: "Write the equation as n + 31 = 113 and subtract 31 from both sides. The answer is 82." should be the correct answer.

Find the real numbers x and y that make the equation true (x+6i)=(3-i)+(4-2yi)​
Ronch [10]

Answer:

x = 7

y = -7/2

Step-by-step explanation:

(x+6i)=(3-i)+(4-2yi)​

First look at the real parts

x = 3 +4

x = 7

Then look at the imaginary part

6i= -i -2yi

6 = -1-2y

Add 1 to each side

6+1 = -2y

7 = -2y

Divide by -2

7/-2 = y

How would I solve this
irinina [24]

Answer:

  • 570 mph
  • 610 mph

Step-by-step explanation:

Let x represent the speed of the slower plane. The faster plane's speed is then x+40. The sum of speeds is ...

   x + (x+40) = 1180

  2x = 1140 . . . . subtract 40

  x = 570 . . . . . .divide by 2

  x+40 = 610 . . . . the speed of the faster plane

The two speeds are 570 mph and 610 mph.
