Answer:
41
Step-by-step explanation:
x+(x+70)+28=180
x+x+70+28=180
2x+70+28=180
2x+98=180
2x=180-98
2x=82
x=82/2
x=41
Answer:
x and y = 66.5
Step-by-step explanation:
180-47=133
133/2=66.5
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
Answer:
DNE
Step-by-step explanation:
The the given table, we have;
As x approaches -14 from the left, at x = -14.001, p(x) = 1.96

As x approaches -14 from the right, at x = -13.999, p(x) = 1.97

The value of p(x) when x = -14 is
= Undefined, or is not definable, therefore, p(x) Does Not Exist (DNE) when x = -14, and we have;
Does Not Exist, DNE.
For this case we must represent the following expression algebraically:
"eight more than the product of a number and two"
Let "x" be the variable that represents the unknown number
We have to:
the product of a number and two is represented as: 
Then, the full expression will be:

Thus, we use multiplication and addition.
