Answer:

$1 \frac{7}{8}$

Step-by-step explanation:

$\frac{3}{5} \ of \ 3\frac{1}{8}$

"Of" means multiplication:

$\frac{3}{5} \times 3\frac{1}{8} \\\\$

Convert whole fraction to improper:

$\frac{3}{5} \times \frac{25}{8} \\\\$

Reduce 25 and 5, by 5.

$\frac{3}{1} \times \frac{5}{8} \\\\$

Multiply the numbers in the numerator together:

$\frac{15}{8} \\\\$

Convert to mixed fraction:

$1 \frac{7}{8}$

Helen made a scale drawing of an office building. A desk, which is 6 feet long in real life, is 2 inches long in the drawing. Wh

frez [133]

Answer:

1 inch = 3 feet

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

6 /2 = 3

1 in = 3 feet

Find the area of the shaded region.

gulaghasi [49]

Answer:

SOLUTION,

HERE,

Area of whole fig= l×b

=5×15

=75 sq.in

Area of unshaaded part=l×b

=3×8

=24 sq.in

Area of shaded part=(Area of whole fig)-(Area of unshaded part)

=75-24

=51 sq.in

hope it helps u :)

X+6y=27 7x-3y=9 por metodo de igualacion

GalinKa [24]

Answer:

(3,4)

Step-by-step explanation:

The system of equations is:

x+6y=27

7x-3y=9.

I looked up "metodo de igualacion". It is basically American for doing substitution.

However, the only difference is you are asked to solve both equations for a variable.

The first equation looks easy to solve for x. So I'm going to solve both equations for x.

x+6y=27

Subtract 6y on both sides:

x =-6y+27

7x-3y=9

Add 3y on both sides:

7x =3y+9

Divide both sides by 7:

x =3/7 y +9/7

So both equations are solved for x. You want to find when the x's are the same because you are looking for a common amongst the lines given.

So we have

-6y+27=3/7 y +9/7

I hate the fractions honestly so I'm going to multiply both sides by 7 so they will no longer be for now:

-42y+189=3y + 9

Now add 42y on both sides:

189=45y+9

Subtract 9 on both sides:

180=45y

Divide both sides by 45:

4=y

If 4=y, then y=4.

So now once we have obtain 4 for y, we will use one of the equations given along with it to find x. Just choose one. Choose the easier looking one to you.

I like the x=-6y+27 with y=4.

So replace y with giving you:

x=-6(4)+27

x=-24+27

x=3

So the solution is (x,y)=(3,4).

x=3 and y=4.
