You can solve this quickly by finding the difference in prices first.

Now - multiply 4 shirts by .50 = $2

That is the SAVINGS for 4 shirts at the cheaper place

Complete the statement If x/7 = 5/3, then x+7/7 =?
lawyer [7]
Lets get started :)

\frac{x}{7} = \frac{5}{3}
We can cross multiply, to find the value of x
3x = 7 x 5
3x = 35
We have to divide by 3 on either sides to isolate x
\frac{3x}{3} =  \frac{35}{3}
3 and 3 cancels out

x = \frac{35}{3}

Then, x + \frac{7}{7}  ( 7 divided by 7 is 1)
\frac{35}{3} + 1   = \frac{38}{3}

Kelly has a rectangular fish aquarium that measures 18 inches long, 8 inches wide, and 12 inches tall.
BigorU [14]

Answer:

a) The maximum amount of water the aquarium can hold is 1728 in³.

b) The cover has to be 624 in² big.

Step-by-step explanation:

a) The maximum volume of water that the aquarium can have is the same as the volume of the aquarium:

V=L×W×H=18 in × 8 in × 12 in= 1728 in³

b) The protective covering is used on the four walls of the aquarium. We have to find the areas of the four walls:

One of them is given by the multiplication of the width and the height:

A₁= W×H= 8 in × 12 in=96 in²

The other area is given by the multiplication of the length and the height:

A₂= L×H= 18 in × 12 in= 216 in²

As the fish aquarium is rectangular the area of the walls is given by:

A_T=2A_1+2A_2=2×96 in²+2×216 in²=624 in²

How do you find the value for x? <br> Find the value of x ?
bogdanovich [222]

Answer:

x = 27

Step-by-step explanation:

Both angles together form 180 degree.

Set your formula up as

180 = (5x+2) + (x + 16)

180 = 5x + 2 + x + 16

180 = 6x  + 18

180 - 18 = 6x

162 = 6x

162/6 = x

27 = x
