Answer:

As far as I can tell, the answer's the second one! (-2+)!

Step-by-step explanation:

(+3+3) AKA 3+3=6. Not -2

(-2+) AKA -2. Is -2!

(-2+ ) AKA -2+?. Could answer -2 but the space after the positive sign concerned me enough to cross it as not -2...

-3 +15 AKA -3+15=12. Not -2.

-2 +15 AKA -2+15=13. Not -2.

-2 - 15 - 2 AKA -2-15-2=13. Not -2.

There's my answer but since it has weird options with how each is given, I could be wrong? Not 100% sure but it's worth the try! Please mark me brainliest if I'm correct!

|7x-7|+3 = 4x+1 ⇒⇒⇒ add (-3) to both sides

∴ |7x-7| = 4x - 2

According to the absolute rule
∴ 7x - 7 = 4x - 2 OR -(7x - 7) = 4x - 2
7x - 4x = 7 - 2 l 7x - 7 = -4x + 2
 3x = 5 l 7x + 4x = 2 + 7
x = 5/3 l 11 x = 9 ⇒⇒⇒ x = 9/11

∴ x = 5/3 and 9/11

So, the correct answer is option B. 5/3 and 9/11

If 3 quarts of paint are needed for 50 ft of fence, how many quarts are needed for 300 ft of fence?

Zina [86]

Answer:

Step-by-step explanation:

First, you would do a proportion

$\frac{3}{50}$ = $\frac{x}{300}$

Then you would cross multiply, getting 50x=900.

After that, you would do 900/50, which is 18.
