The difference between two numbers is 8. the lesser number is a. write an expression for the greater number

x+x-2=8 or 2x-a=8

Step-by-step explanation:

X+x-a=8

2x-a=8

2x=a+8

2x/2=2/2+8/2

X= 1+4

X=5

5+5-a=8

10-a=8

-a=8-10

-a= -2

A= -2/-1

A=2

5+5-2=8

10-2=8

8=8 it checks

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

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
