Answer:
n=16
Step-by-step explanation:
Let's solve your equation step-by-step.
1/
2
n−3=5
Step 1: Add 3 to both sides.
1/
2
n−3+3=5+3
1/
2
n=8
Step 2: Multiply both sides by 2.
2*(
1/
2
n)=(2)*(8)
n=16
Answer:
n=16
Answer:
middle brother = x
older brother = x+1
younger brother = x-1
x-1+x+x+1=129
3x+0=129
3x=129
x = 43(middle brother)
43-1 = 42(younger brother)
43+1 = 44(elder brother)
Check:
43-1+43+43+1=129
42+43+44=129
129=129
Answer:
2/3
Step-by-step explanation:
The slope is simply the number that is multiplied to x.
In this case, it is 2/3. So, that is the slope.
The other number, -7, is the y-intercept of the line, which is where the line intersects the y axis.
First, you factor the expression.
x (x - 54/125)
