Mathematics
1 answer:
Masja [62]2 years ago
7 0

Answer:

Step-by-step explanation:

It is hard to read but (5x - 2) + (7x - 9)  =  AC    also  5x - 2   =   7x - 9

    5x - 2 = 7x - 9         subtract 5x from both sides then add 9 to both sides

5x - 5x - 2 + 9  = 7x - 5x - 9 + 9

   -2 + 9 = 7x - 5x

          7  =  2x

        3.5  =  x

    5x - 2 = 7x - 9    

         3   ≠    -2                        when x = 1

         8   ≠     5                        when x = 2

        13   ≠    12                        when x = 3

     15.5   =    15.5                     when x = 3.5

        18   ≠    19                        when x = 4

LMN≅PQR
tresset_1 [31]
<span>LMN≅PQR means that point L is equal to P, point M is equal to Q, and point N is equal to R. All lines are the same.

Point Q has an angle of 72, which means that point M also has an angle of 72.

Now you have two angles to find x. All interior angles of a triangle add up to 180, so you can set up the following equation to find x:

72 + 36 + x = 180

Subtract 36 from both sides.

72 + x = 144

Subtract 72 from both sides.

x = 72

The angle of point L, x, is 72.

You went shopping last weekend and bought a new shirt. The shirt had an original price of $39.00 but it was on sale for 35% off
balandron [24]

Answer:

$26.87

Step-by-step explanation:

if the shirt was 35% off, then you paid 65% of the cost

that value can be found by:

39 x .65 = 25.35 (this is the amount paid for the shirt)

sales tax of 6% on 25.35 is:

.06 x 25.35 which equals 1.52

25.35 + 1.52 = 26.87
