Answer:
x = 2, y = 1
Step-by-step explanation:
x + 4y = 6 and y = 3 - x have to be rearranged: x + 4y = 6 and x + y = 3
You subtract the equations to eliminate one of the variables (x) so that the other can be found
So, it is asking for 150 is 23% of what
So, the answer is 652.17
I think
Hope this helps :D
Answer:
Step-by-step explanation:
If you are saving 25%, you are still paying 75%, right? So the cost of the TV with a discount of 25% is 192.74(.75) which is $144.56
That's the cost of the TV on sale. Now we need to find the sales tax amount, if the sales tax is .05 as a decimal. We are paying $144.56 for the TV, which is 100% of the cost. On top of that, we are paying another 5%. So altogether, for the TV, we are paying 105% of the TV. Therefore,
144.56(1.05) = $151.79
Answer:
31
Step-by-step explanation:
x+24+4x+1=180
5x+25=180
5x=155
x=155/5=31
Answer:

Step-by-step explanation:
We want to find the equation of the line that goes through: !6,-10) and is perpendicular to the line

Let's simplify the equation of the line to get:


The slope of this line is -5.
The perpendicular to this line has a slope of

The equation going through (6,-10) is

We substitute to get;

Expand;
