Answer:

21/25 = 84/100

17/20 = 85/100

21/25 < 17/20

Step-by-step explanation:

∵ The common multiple of 25 and 20 is 100

∵ 100 ÷ 25 = 4

∴ 21/25 = (21 × 4)/(25 × 4) = 84/100

∵ 100 ÷ 20 = 5

∴ 17/20 = (17 × 5)/(20 × 5) = 85/100

∵ 84 < 85

∴ 84/100 < 85/100

∴ 21/25 < 17/20

Which of the following shows the solution to the inequality

otez555 [7]

Answer:

I got x = 1

Step-by-step explanation:

First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:

$1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1$

And since -2.5 is less than -1 this statement is true. x does in fact equal 1
