Betty was making a new flag. She wanted the stripes to alternate colors. She needed a total of 13 stripes and wanted 1 more red stripe than she has white stripes.

w+w+1=13 or 2w = 12

Step-by-step explanation:

Total no. of strips = 13

Let there are w white stripes.

Red strips = w+1

ATQ,

Red strips +white strips = 13

w+w+1=13

2w+1=13

2w = 13-1

2w = 12

Hence, this is the required equation.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

to determine the unit cost your would divide the total cost by the number sold.
