Answer:
x=6
Step-by-step explanation:
To solve, we need to get the variable, x, by itself. To do this, first, move all the variables to one side of the equation, and the numbers to the other
2/3(15x-6)=8(x+1)
First, distribute the 2/3 on the left
2/3*15x + 2/3*-6=8(x+1)
10x-4=8(x+1)
Next, distribute the 8 on the right
10x-4=8*x + 8*1
10x-4=8x+8
Subtract 8x from both sides
10x-8x-4=8x-8x+8
2x-4=8
Add 4 to both sides
2x-4+4=8+4
2x=12
Now all the numbers are on one side, and the variables are on the other. x is not by itself though, it is being multiplied by 2. To undo this, divide both sides by 2
2x/2=12/2
x=6
Answer:
x=4
Step-by-step explanation:
3(x+2) = 2(x+5)
Distribute
3x+6 = 2x+10
Subtract 2x from each side
3x-2x+6 = 2x-2x+10
x +6 = 10
Subtract 6 from each side
x+6-6 = 10-6
x = 4
Answer:
-243
Step-by-step explanation:
Since your finding the 36th term and you know the equation plugin 36(as n) into the arithmetic sequence.
-7(36)+9 = -243
Answer:
A variable (such as x) - 3
105$
Because she drove 5 miles which is 60$ then the truck was 45$ so 45$ + 65$ = 105$
