Let you = y
Let your brother = b

y = 15
b = y + 3

Plug in 15 for y

b = 15 + 3
b = 18

Your brother picked up 18 shells.

Hope this helps

Let's put this into an equation.
You picked up 15. So that means you=15.
You brother = X
He picked up three more than you. Since you=15, the equation would look like:
15+3=X
Now add so that there is one number.
15+3=18=X
So, your brother picked up 18 shells.
Tell me if this helps!!!

A piece of paper is in the shape of a rectangle the piece of paper is 1 5/8 inches wide and 8 3/4 inches long a student cuts of
Helga [31]

Answer : The area of the 12 equal long pieces is, \frac{455}{6144}in^2

Step-by-step explanation :

As we are given that:

Width of rectangle = 1\frac{5}{8}in=\frac{13}{8}in

Length of rectangle = 8\frac{3}{4}in=\frac{35}{4}in

When student cuts of 3/4 from width and 3/4 from height then the new width and length of rectangle will be:

New width = \frac{13}{8}-(\frac{13}{8}\times \frac{3}{4})=\frac{13}{8}\times \frac{1}{4}=\frac{13}{32}in

New length = \frac{35}{4}-(\frac{35}{4}\times \frac{3}{4})=\frac{35}{4}\times \frac{1}{4}=\frac{35}{16}in

Now student cuts in 12 equal long pieces.

New length = \frac{\frac{35}{16}in}{12}=\frac{35}{192}in

New width = \frac{13}{32}in

Now we have to calculate the area of the 12 equal long pieces.

Area of rectangle = Length × Width

Area of rectangle = \frac{35}{192}in\times \frac{13}{32}in

Area of rectangle = \frac{455}{6144}in^2

Therefore, the area of the 12 equal long pieces is, \frac{455}{6144}in^2

A quart of paint covers 80 square feet. How many quarts should you buy to paint the ramp with two coats? (Assume you will not pa
Amanda [17]

Answer:

Step-by-step explanation:

Alright, lets get started.

We first need to find the surface area of the ramp without its base.

The ramp consists 4 sides two triangles and two rectangles.

Area of 1 triangle = \frac{1}{2}*14*6=42

Area of 2 triangle = 42

Area of top rectangle = 15.2*19.5=296.4

Area of back rectangle = 6*19.5=117

So total area =  42+42+296.4+117=497.4 square feet

We are asked to paint two coats of paint means we have to double the area.

So the double area is = 2*497.4=994.8

80 square feet requires = 1 quart of paint

994.8 square feet requires = \frac{994.8}{80}=12.435

12.4 quart can't be purchased so complete number of quart will be 13 quart.   :   Answer

Hope it will help :)
