Answer:
66 notes of 5 riyal
76 notes of 10 riyal
Step-by-step explanation:
(10x + 10) +5x = 1000
15x = 990
x = 66
so there are 66 of 5 riyal notes and 66 + 10 ie 76 of 10 riyal notes
The inverse is b. If 4x+1 .NE. 61, then x-5 .NE.10
Answer:
414
Step-by-step explanation:
n is our variable, so substitute n for 26.
50 + (14*26)
264 + 50 = 414
Well first lets add up all the students to see how many there are to split.
22 + 26 = 48
Now, let's split that into four groups.
48/4 = 12
So there will be 12 people in each group.
If u work it out and both sides don't equal, then there is no solution.
Example :
2x + 4 = 2x + 6
2x - 2x = 6 - 4
0 = 2....this is incorrect...therefore, there is no solution
