Answer:

b=3in

Step-by-step explanation:

SO first of all, the formula for area is lxw (length x width)

And our question tells us that

l x w=24in^2

4 x w = 24 (question tells us that length is 4 inches as listed on side)

4 x (b+3) = 24 (b+3 is the total width of the postcard)

4b + 12 =24 (multiply by 4 inside the bracket)

4b=12 (subtract 12 from both sides)

b=3 (solve for b by dividing by 4)

if eight times a number is increased by 3 the result is 19 more than six times this digit. find the number
Verdich [7]

Answer:

8

Step-by-step explanation:

Even though we don't know the number yet, let's name this number "n".

8n + 3 = 6n + 19

8n + 3 - 6n = 6n + 19 - 6n

2n + 3 = 19

2n = 16

n = 16/2

n = 8

Our number is 8.

Note: This answer is 100% correct.

An acid is a substance that increases the concentration of H3O+ ions in solution. Look at the reaction below of phenol (C6H5OH)
Law Incorporation [45]

Answer:

The reactant that acts as an acid, by contributing an H⁺ ion to create H3O+ in the chemical equation is C₆H₅OH.

Step-by-step explanation:

According to Brønstend-Lowry, an acid is a substance that transfer a proton (hydrogen cation, H⁺) to a base, forming a base conjugate for the first and an acid conjugate for the second.      

From the following reaction:

C₆H₅OH(aq) + H₂O(l)  →  C₆H₅O⁻(aq) + H₃O⁺(aq)

   

We have that the C₆H₅OH transfer a proton to the water to form its conjugate base C₆H₅O⁻ and the conjugate acid of water H₃O⁺. Hence, the C₆H₅OH is the acid and the water is the base.

Therefore, the reactant that acts as an acid, by contributing an H⁺ ion to create H3O+ in the chemical equation is C₆H₅OH.

I hope it helps you!
