Answer:
x=10 n=18.5 s=6
Step-by-step explanation:
4x-10=30
Add 10 to both sides
4x-10+10=30+10
4x=40
Divide by 4 on both sides
(4x)/4=40/4
x=10
2n-7=30
Add 7 to both sides
2n-7+7=30+7
2n=37
Divide by 2 on both sides
(2n)/2=37/2
n=18.5
(s/3)+2=4
Subtract 2 from both sides
(s/3)+2-2=4-2
(s/3)=2
Multiply by 3 on both sides
3s/3=2*3
s=6
Answer:
The value of y is 48.
Step-by-step explanation:
You have to substitute the values into the equation :




Answer with Step-by-step explanation:

So in this sequence,
1st term = 7
2nd term = 10
3rd term = 13
4th term = 16
10th term = 34

In this sequence,
1st term = -1
2nd term = 3
3rd term = 7
4th term = 11
10th term =35
5 - substitute the numbers 1-10 for n in (3n-4) and add up all your answers. So (3(1)-4) + (3(2)-4)...
