Answer:
140
Step-by-step explanation:
Rewording the problem will make it easier to write the equation you need to solve this. Think of it in simpler terms: "7 is 5% of how many?". "7" is just a 7; the word "is" means =; "5%" is expressed as its decimal equivalency (.05); the word "of" means to multiply; and "how many" is our unknown (x). Putting that all together in one equation looks like this:
7 = .05x
Solve for x by dividing both sides by .05 to see that
x = 140
7(x+3)
= 7x+ 7*3 (distributive property)
= 7x+ 21.
The final answer is 7x+21~

Answer:
Equation: x+3<12 Answer: x<9
Step-by-step explanation:
SO bascially what you do is you find the equation based on the wording (The sum of a number and three is less than twelve) and after you find the equation (which is x+3<12), you subtract 3 from both sides, getting x<9
