6 times 5 equals 30 and 30 times 3 is 90 so 5 is your answer
Answer:
4n + 16
Step-by-step explanation:
Difference = +4 each time
20 - 4(1) = 16
Therefore nth term = 4n + 16
Proof:
4(2) + 16 = 24
4(3) + 16 = 28
Answer: 333 chemistry books and 111 biology textbooks
Step-by-step explanation:
444=x+y
x=3y
4y=444
y=111
x=chemistry
y=biology
Answer:
-83
Step-by-step explanation:
x+(x+1)=number
x+(x+1)=-165
2x+1=-165
-1 -1
2x=-166
/2 /2
x=-83
We can check our work by adding -83+-82=-165 because -83 would be the smaller number.
-83.
