Answer: z=6
Step-by-step explanation:
4(z-3)=2z
4z-12=2z subtract 2z from both sides
2z-12=0 add 12 to both sides
2z=12 divide 2 to both sides
z=6

Answer:
x=0
Step-by-step explanation:
Simplifying
8x + 5x = 0
Combine like terms: 8x + 5x = 13x
13x = 0
Solving
13x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '13'.
x = 0

Adam is d years old and Brandon is b
old and Brandon is b years older than Adam.
In how many years will Brandon be twice as old as Adam is now?
Answers
Answer:
-b years from now
Step-by-step explanation:
The age of Adam = d
The age of Brandon = b
The number of years Brandon is older than Adam = b
Therefore;
b = d + b
∴ d = 0
Therefore, Brandon will be twice as old as Adam is now when Brandon is 2 × 0 = 0 years
The number of years before Brandon will be twice as old as Adam is now = 0 - b = -b years from now

Lines m and n are drawn in the coordinate plane. The equation of line m is y=-3x+8 and line n goes through point (-4,-11). When a transversal of the two lines is constructed the alternate interior angles formed by the transversal are congruent. What is the equation of line n?
Answers
Answer:
The equation of line n is;
y = -3x - 23
Step-by-step explanation:
Here, we want to find the equation of line n
For the alternate interior angles to be congruent after drawing the transversal, then both lines must be parallel
If the two lines are parallel, then their slopes are equal
To get the slope of line m, we compare the equation of line m to the standard form
The equation of line m is y = -3x + 8
if we compare this with the standard form which is y = mx + c
Then the slope of line m is -3 and since they are parallel lines, the slope of line n is -3 too
So now, we need to get the equation of line n
It passes through (-4,-11)
What we have already is;
y = -3x + c
we need to get the y-intercept to write the complete equation
To get the y-intercept we simply substitute for (-4,-11)
Thus, we have
-11 = -3(-4) + c
-11 = 12 + c
c = -11-12 = -23
The equation of line n is;
y = -3x - 23

Plz help mee
Answers
Step 1:
The variable is the number of weeks needed to equalize Alexa and her sisters savings.
Step 2:
7x + 60 = 5x + 120
Step 3:
7x+60=5x+120
Subtract 60 from both sides.
7x+(60-60)=5x+(120-60)
7x=5x+60
Subtract 5x from both sides
7x-5x=5x+60-5x
2x=60
Divide both sides by 2.
2x/2 = 60/2
x=30
Step 4:
7(30) + 60 = 5(30)+ 120
210+60=150+120
270 = 270
Step 5:
To find the unknown amount of weeks, you need to rewrite the equation isolate x on the left-hand side of the equation. I just subtracting/simplified the equation until I could solve it.
