Answer:

x=10

Step-by-step explanation:

For number 19.

The equation you get is:

X+2=6(2) this is because 5x2=10, so you have to do the same here.

so, X+2=12

-2 from both sides and you get

x=10

Write an equation of the line that passes through the given points. (0,−3),(3,3)

Delicious77 [7]

I find it easiest to use slope-intercept form, or y=mx+b, to do this.

First, find the slope. 6/3 = 2/1 = 2. m = 2.

Next, find the y-intercept. In this case they gave it to you directly. b = -3.

So, the equation would be y = 2x - 3.

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.
