First, lets comprehend the question.

A complement of a number is a number in which added to the number, it will be measure 90.
The phrase: "More than" means you gotta add it
The phrase: "twice the complement of the number" means you gotta multiply the complement by 2.

Next step, solving.
To get the complement of 42° we must subtract it by 90°.
So 90-42=48. So the complement of 42 is 48 since they both add up to 90.
Now it says here to multiply the complement twice. So multiply 48 by 2

iogann1982 [59]
Answer: The word "ensures" implies that it is certain.

In the case of the study, they simply found that the average salary is greater for college graduates. This doesn't mean that in every case the college graduate makes more money.

The problem is the word "ensures". Our study doesn't show certainty only a general pattern.

26. A book costs sh. (x - 300) and a pen costs sh (x + 100). If Ndagire pad sh. 3300 for 3 books and 2 pens, how much did she pa
saul85 [17]

Answer:

500 and 900

Step-by-step explanation:

3(x - 300) + 2(x + 100) = 3300 ← distribute parenthesis

3x - 900 + 2x + 200 = 3300

5x - 700 = 3300 ( add 700 to both sides )

5x = 4000 ( divide both sides by 5 )

x = 800

Then

cost of book = x - 300 = 800 - 300 = 500

cost of pen = x + 100 = 800 + 100 = 900
