In a group of 50 students 38 play chess and 24 play scrabble. How many plays both chess and scrabble.
Grace [21]

Answer:

12

Solve:

to solve, first add both partial numbers together

38 + 24 = 62

then subtract the whole number

62 - 50 = 12

Step-by-step explanation:

the way this works is the overflow when adding the two numbers, is the amount of students that do both, they count in both groups meaning their counted twice, this means that if each student dropped a coin for what they played (1 for chess and/or 1 for scrabble) the 12 students who played both would drop two coins

not a professional explanation but i hope it makes sense ^^

A $5000 loan was to be repaid with 8% simple annual interest. A total of $5350 was paid. How long was the loan outstanding?
Dovator [93]
<span>1.       </span><span>Loan = 5000 dollars
Every years = 8% interest
Paid a total of 5350 dollar
Find the term of the loan
=> 8% = 8/100
=> .08
=> 5000 x .08 = 400, but he only paid 350 as interest that means the term is less than 1 year
=> In a year, there are 12 months, so that’s equals
=> 12 months / 8% interest
=> 1.5, every month his loan is increasing 1.5%
=> 5000 x 0.07 = 350
=> 7 percent x 1.5 percent = 10.5
Thus, he paid 5350 dollars for his 10 months loan

True or false, y - 3 = -2 (x + 4) written in slope intercept form looks like y = -2x - 5
marysya [2.9K]

Answer:

The line you're looking for is parallel to y = 3x – 9, so it also has a slope of 3. Thus, you can rule out ... Here's what your work should look like: y = mx + b 0 = 3(–3) + b 0 = –9 + b 9 = b Now that you know both the slope and the y-intercept for this line, you can write the equation in the slope-intercept form: y = mx + b y = 3x + 9 The correct answer is Choice (C). What is the equation of a line that passes through the point (0, 3) and is perpendicular to y = 8x + 5? (F) y = 8x (G) y = 8x + 3 (H) (J)
