It's basically 5,000*2=10,000
and 10,000/2=5,000. your answer would be either they multiplied 5,000 by 2 and 10,000 divided by 2, they increased the sales by 5,000
First, you add up the total number of students because we would base our percentage one this.
Total number of students = 1+4+5+10+20+10+5
Total number of students = 55
Now, let's count how many of them got a score of more than 70. For this, you would only count the students belonging to 70-under 80, 80-under 90 and 90-under 100.
Students who got more than 70 = 20+ 10 + 5 = 35
Therefore the percentage is equal to:
Percentage = 35/55 * 100 = 63.64%
Step-by-step explanation:
By substitution method
6x+3(2x)=12
6x+6x =12
12x=12
x=1
y=2x
y=2*1
y=2
The answer is C. Because if g equals 4 you multiply 11 times 4 to get 44 then it is a quite simple problem 44 + 5 = 49
Answer:
2n+7
Step-by-step explanation:
+2 +2 +2 +2
9 11 13 15 17 so we start with 2n
2 ➡ 9 = +7 6 ➡ 13 = +7
4 ➡ 11 = +7 8 ➡ 15 = +7
So the answer is 2n + 7
