It is 7r-8 because you combine like terms


-r + 6+8r-14
You subtract r to 8r which is 7r

So now it is 7r + 6 - 14

Then you add 6 to -14 which is -8

And you get 7r -8

Arlecino [84]

Answer:

Let v = ml of 100% vinegar

Then 150-v = ml of dressing

v  + .05(150-v) = .24(150)

v + 7.5 - .05v = 36

.95v = 28.5

v = 28.5/.95

v = 30 ml of vinegar

dressing = 150-30 = 120 ml

Is my student correct?​
tino4ka555 [31]

Answer:

Yes

Step-by-step explanation:

There hasn't been a chemical change, rather, just a physical change. All that had happened was a liquid turning into a solid, which doesn't require a change in elements of the liquid itself.

Which of the following equations has no real solutions?
vovangra [49]

Answer:

D.

Step-by-step explanation:

A.

9 (x - 3) = 9x - 27 ➡ 0 = 0 (this has infinite solutions)

B.

9x - 3 = 9x - 3 ➡ 0 = 0 (has infinite solutions)

C.

9x - 3 = 27x - 3 ➡ x = 0 (has one solution)

D.

9 (x + 3) = 9(x + 10) ➡9x +27 = 9x +90➡ 9x -9x = 90 - 27 ➡ 0 = 63 (doesn't make sense so it has no solution)

Name the coordinates of the final image of the figure after the given sequence of
slega [8]

9514 1404 393

Answer:

  • S''(5, -3)
  • T''(1, 0)
  • U''(4, 1)
  • V''(4, 0)

Step-by-step explanation:

The end result after the final transformation is ...

  (x, y) ⇒ (-x, y)

so, each x-coordinate is negated. The transformed coordinates are ...

  S(-5, -3) ⇒ S''(5, -3)

  T(-1, 0) ⇒ T''(1, 0)

  U(-4, 1) ⇒ U''(4, 1)

  V(-4, 0) ⇒ V''(4, 0)
