Answer:

7) First Circle

8)Also First Circle

Step-by-step explanation:

For the first one simplify the bottom expression to get (x-3)(x+7), then cancel out the numerator and x+7 to get 1/x-3. The restrictions are when you solve for x-3 and x+7

The second one is the same thing but this time we simplify the numerator to get (x+2)(x-5). Then, cancel out both x+2. Then you get x-5 as the answer and the restriction is -2 because x+2 is the denominator.

Hope this helps!

ALGEBRA 1 HELP!! Andrea buys 4 bags of granola and 3 bags of dried fruit. She spends $51.50. Carter buys 2 bags of granola and 4
timurjin [86]

Answer:

Granola is $6.95/bag and Dried Fruit is $7.90/bag.

Step-by-step explanation:

Let G and F stand for the cost of 1 bag Granola and 1 bag dried Fruit.

We learn that Andrea's total was $51.50.  Her purchase can be written as the sum of the cost of 4 bags granola (4G) and 3 bags fruit (3F):

   4G + 3F = $51.50

We can do the same for Carter:

   2G + 4F = $45.50

We have two equations and two unknowns, so we should be able to solve for both unknowns.  To do this, we need to find a way to eliminate one of the unknows in a single equation.  Let's rearrange Carter's equation to isolate G on one side:

2G + 4F = $45.50

2G  = $45.50 - 4F

G = ($45.50 - 4F)/2

Now use this expression for G in Andrea's equation:

4G + 3F = $51.50

4(($45.50 - 4F)/2) + 3F = $51.50

2($45.50 - 4F) + 3F = $51.50

($91.00 - 8F) + 3F = $51.50

-5F = - $39.5

F = $7.90  <u>One bag of dried fruit is $7.90.</u>

Now use this value for F in either equation for find G:

2G  = $45.50 - 4F

2G  = $45.50 - 4($7.90)

2G = $13.90

G = $6.95   <u>One bag of granola is $6.95</u>

---------------

Check to see if these values work:

<u>Andrea: </u>

4G + 3F = $51.50  :

4($6.95) + 3($7.90) = $51.50  ?

$51.50 = $51.50   <u>YES</u>

<u>Carter:</u>

2G + 4F = $45.50

2($6.95) + 4($7.90) = $45.50  ?

$45.50                     =  $45.50   <u>YES</u>

<u></u>

QRST is a rectangle. If RT = 4x – 16 and SQ = x + 5, find the value of x.
Vsevolod [243]
If you draw the figure, RT and SQ turn out to be the diagonals of the rectangle since diagonals of a rectangle are equal, so RT = SQ ==> 4x - 16 = x + 5 ==> 4x - x = 5 + 16 ==> x = 21/3 = 7
