Answer:
Step-by-step explanation:
let the length of rectangle=l units
width=9
p=2(l+9)
area=9l
9l=2(l+9)
9l=2l+18
7l=18
l=18/7 units
Answer: x < 2
Step-by-step explanation:
Let's solve your inequality step-by-step.
6.2x+1<21−3.8x
Step 1: Simplify both sides of the inequality.
6.2x+1<−3.8x+21
Step 2: Add 3.8x to both sides.
6.2x+1+3.8x<−3.8x+21+3.8x
10x+1<21
Step 3: Subtract 1 from both sides.
10x+1−1<21−1
10x<20
Step 4: Divide both sides by 10.
10x/10 <20x/10
x < 2
Answer:
