I just know that 2 is X = 6

Answer:

for the first one, it's x=11. first, you have to subtract 6 from both sides (-2x+6-6=-16-6) then you simplify that so you get -2x=-22, and from there you divide both sides by -2

getting -2x/-2=-22/-2 then you simplify that and get x=11

and for the second one x=-7. first, you have to add 10 to both sides

(-10+5x+10=-45+10) then simplify that down to 5x=-35 then divide both sides by 5 (5x/5=-35/5) then simplify that down to x=-7

Let's resolve the powers of 10 to make them comparable

47000

45000

5000

280000

125000

Now you can see the largest is 280000 and the smallest is 5000

Their difference is 280000 - 5000 = 275000

Given the vectors w = <-5, 3> and z = <1, 4>, find the results of the vector subtractions. -w − z = z − w = w − z =
Elodia [21]

Answer:

Concept: Linear Algebra

  1. Given two linearly independent vectors w and z
  2. We want -w-z
  3. Hence apply a negative gradient to w
  4. w=-<-5,3> =<5,-3>
  5. So <5,-3>-<1,4> = (<5-1>,<-3-4>)
  6. The answer is <4,-7>

Find the mean and range.<br><br> 26 19 23 39 31 34 23 25
sveticcg [70]
Range: largest number minus the smallest number
39 - 19 = 20
your range is 20

Mean: add all of the numbers and divide by the amount of numbers there are.

26+19+23+39+31+34+23+25= 220
220/8 = 27.5

your mean is 27.5

hope this helps

natta225 [31]

Answer:

12.5(x  + 20) = 460 \\ x + 20 = 460 \div 12.5 \\ x + 20 = 36.8 \\ x = 36.8 - 20 \\ x = 16.8

Hence, 16.8 miles is your answer
