The sum of 8 times a number and 7.....sum means add
8n + 7
is twice the number...is means equals
= 2n
so we have : 8n + 7 = 2n
Last ones in each row
Step-by-step explanation:
count which figure has 18 cubes
First has 12
2nd one has 24
3rd one has 27
4th one has 18
5th one has 18
The answer is 90%. You get this answer by multiplying both the numerator and denominator by 5 so 18x5=90 and 20x5=100 giving you a fraction of 90/100 and a percentage of 90%.
Only if the individual doing the calculation makes a substantial mistake.
Any fraction with the same quantity in the numerator and denominator
always has the value of ' 1 ', (provided only that the quantity is not zero).
Answer:
