A grocery store has 120 bottles of spring
notka56 [123]

Question:

A grocery store has 120 bottles of spring water in stock.  The store orders bottles of spring water in cases of 24.  The store wants to order enough cases of spring water so it has more than 500 bottles in stock.  Which inequality best models this situation?

A.  24x + 120 > 500

B.  24x - 120 > 500

C.  24x + 500 > 120

D.  24(x+120) > 500

Answer:

Option  A.  24x + 120 > 500  is the inequality that best models this situation.

Step-by-step explanation:

The Number of bottles of spring  water in the stock = 120

Each case of the spring water bottles contains 24 bottles

The store wants  to order enough cases of spring water so  that it has over 500 bottles in stock.

So there are already 120 bottles in stock .

The store will order

24x +120  > 500

where x  is the number of spring water bottle cases

Solve 4e^2x-3=12 please help
Anestetic [448]

4*e^{2x} -3 = 12

Step 1:

Here we have -3 in subtraction on the left side, so when we take it to the right we apply opposite operation of subtraction that is addition.

4*e^{2x} = 12+3

4*e^{2x} = 15

Step 2:

Next we have 4 in multiplication on left side, so dividing right side by 4,

e^{2x} = 15/4

e^{2x} = 3.75

Step 3:

taking log on both sides

ln ( e^{2x}) = ln(3.75)

{2x} =ln 3.75

Step 4:

Dividing right side by 2,

x= ln (3.75) /2 = 0.66088

Answer : x = 0.66088..

HELPPPPP NEEDED FIRST GETS BRAINLLEST !!!! Your dad is designing a new garden for your backyard. He has 26 feet of fencing to go
barxatty [35]

Answer:

D

Step-by-step explanation:

Let's call the width of the yard x and the length x + 3½. Since we know that perimeter = 2 * (width + length) and that the perimeter must be 26 we can write:

2 * (x + x + 3½) = 26

x + x + 3½ = 13

2x + 3½ = 13

2x = 9½

x = 4\frac{3}{4}
