Answer:
n+18=7(n-3)
Step-by-step explanation:
Lets replace "A number" with the variable n because we do not know its value!
1) Rewrite the problem as an equation
n+18=7(n-3)
<u>If we want to solve the equation, do the following:</u>
1) Distribute 7 to n and -3:
n+18=7n-21
2) Add 21 to both sides:
n+39=7n
3) Subtract n from both sides:
39=6n
4) Divide both sides by 6:
n=6.5
Answer:
C. I > 4 (or x > 4)
Step-by-step explanation:
first multiply 8 and (x - 5)
8(x– 5) – 3x > -20 -----> (8 * x) - (8 * 5) = 8x - 40 - 3x > -20
add like terms
8x - 40 - 3x > -20 -----> 8x + -3x = 5x - 40 > -20
combine -40 and - 20
5x - 40 > -20 ----> -20 + 40 = 5x > 20
Then finally divide
5x > 20 -----> (5x/5) > (20/5) = x > 4
Hi there! I don’t see any answer choices listed, however this function takes place in the First and Third quadrants of an xy plane. This means that the values will either be at the origin (0,0) or equal numbers with the same sign. For example, (2,2), (-8,-8), and (1.38,1.38) would all be possible points. When looking at points that are given, plug x and y into your equation and see if they give the right answer. If you come across a value with different signs, such as (-4,4) or (9.3,-9.3), that will be excluded from the equation or line on a graph. PS. x-y=0 simplifies to x=y, which might make it a bit easier to look at, and on a graph y=x is simply a diagonal line across quadrants I and III. Let me know if you need any extra help!
I guess that Z is more consistent
