The pesticide DDT is banned in most countries because of its long-lasting toxic effects on
humans and animals. The half-life of DDT is
approximately 15 years. A sample area of soil

step-by-step explanation:

step-by-step explanation:

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
