Ok, so they are all balanced, so each side of the scale thing is equal to the other side.

A. 3 + x = 8
If we subtract 3 from 8, what’s left is 5 for x
x = 5

B. 2y = 12
Both y weights are equal, so dividing 12 by 2 says each y weight is 6.
y = 6

C. 4z = 11
All z weights are equal, so divide 11 by 4 to find the weight of z
z = 2.75

D. 3 4/5 + w = 13 4/5

Subtract 3 4/5 from 13 4/5 to find the weight of w
w = 10

Let me know if you have questions about this.

How would you graph (on a number line) (x-8)(x-8)<0??
Marta_Voda [28]

Answer:

  The graph is the empty number line (no solution)

Step-by-step explanation:

Your expression is (x-8)² < 0. There are no real numbers that give a negative value when squared. There is NO SOLUTION. The graph is empty.

_____

<em>Comment on quadratic inequalities</em>

In general the inequality (x-a)(x-b) < 0 will have a solution when one factor is negative and the other is positive. In general, that will be the case for values of x that are strictly between <em>a</em> and <em>b</em>. In your inequality, that would require you graph numbers that are between 8 and 8. There are none.

163 * 80 − 153 * 47 − 153 * 33 compute in the most rational way BRAINLIEST IF CORRECT
erik [133]

Answer:

820

Step-by-step explanation:

Some people may get confused and just calculate this question from left to right, but I was taught to use this formula:

Brackets

Exponents

Division

Multiplication

Addition

Subtraction

--------

So lets multiply first,

163 × 80 = 13,040

153 × 47 = 7,191

153 × 33 = 5,049

-------

Next, we subtract:

13,040 - 7,191 - 5,049 = 820

------

Have a good day :)
