A woman bought some large frames for $18 each and some small frames for $8 each at a closeout sale. If she bought 21 frames fo

IrinaVladis [17]

Answer:

8 large frames and 13 small frames

Step-by-step explanation:

Given:
$18 each = large frames

$8 each = small frames

To Find:

⇒ Bought 21 frames for $248, find how many of each type she bought

Solve:

1 Large frame costs = 18 $

Therefore, x large frames costs = 18x $

{where x is the number of large frames she bought}

1 Small frame costs = 8 $

Therefore, x Small frames costs = 8y $

{where y is the number of small frames she bought}

By the given condition :

18x + 8y = 248 {equation 1}

x + y = 21 {equation 2}

Solve these equations simultaneously, from second equation we get :

x = 21- y

18⋅(21−y)+8y= 248

378 - 18y+8y = 248

-10y = -130

y = 13

Put y = 13 in eq x = 21- y

x = 21 - y

x = 21 - 13

x = 8

So the woman bought 8 large frames and 13 small frames.

Choose any four consecutive even numbers. (For example: 6, 8, 10, 12). Multiply the two middle numbers together. (e.g. 8 x 10 =

Ludmilka [50]

Answer:

Step-by-step explanation:

let the consecutive even numbers be 2n-2,2n,2n+2,2n+4 where n>0 and n is an integer.

2n(2n+2)-(2n-2)(2n+4)

=4n²+4n-(4n²+8n-4n-8)

=4n²+4n-4n²-8n+4n+8

=8

Need help with math plz

marishachu [46]

Answer:

see below

Step-by-step explanation:

1). 8 radii are shown, there are 8 straight lines going from the center of the circle to the edge of the circle

2) diameter = d, radius = r. given radius r ,

d = 2r

d = 2(14.5) = 29

the diameter is 29 cm

3)using d = 2r

7x+5 = 2(13) = 26

7x = 21

x = 3

4)the length of the diameter is increased 3 times

d1 = 2r,

d2 = 2(3r) = 6r

we see that the diameter whose radius is 3 times longer is 3 times larger than the diameter whose radius is 1 times as long.

5) they can find the diameter of the circular path, then find the radius, go from one point on the circular path and go r distance
