Hey there! :)
Answer:
A. x = 5.
Step-by-step explanation:
Starting with:
4x + 1 = 21
Subtract 1 from both sides:
4x + 1 - 1 = 21 - 1
4x = 20
Divide both sides by 4:
4x/4 = 20/4
x = 5.
A.X=5
4x+1=21
-1=-1
4x=20
4x/20 = 5
or just plug in five for x and you get 21
25+24= 49coins 49÷2.5 is 19.5 so there are 19.5 dimes in the bag I believe
Consider the intergers as, x and x+1
x+(x+1)=31
2x+1=31
2x=30
x=15
So, (x+1)=(15+1)=16 would be larger number.
10
