Answer & Step-by-step explanation:
7). C = 44
8). S = 40
9). S = 40
10). T = 118
You can write in the comments if you want an explanation.
Hope this help ;)
If you look at numbers 1 to 100, and matched up numbers, like this:
1+99
2+98
3+97
and so on, you would always get 100. So, when you add up all the numbers besides 100, you will get 100.
Hope I helped, sorry if I'm wrong.

Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180°
6p + 6p + 3 p = 180
15p = 180
p = 180/15
p = 12
Angles are:
6p = 6*12 = 72°
3p = 3*12 = 36°
Angles are: 72°, 72° , 36°
Answer:
L=$24.95 , G=$12.75
Step-by-step explanation:
This problem is a classic system of equations problem. There are several methods of solving these problems, because of the circumstances and values given I think it's best to use the elimination method. The elimination method attempts to cancel out a variable by subtracting one equation from another.
The first statement Marie received an order of 5 trays of lasagna and 3 trays of garlic bread for a total of $163. I'm going to use "L" for lasagna and "G" for garlic bread. Therefore, the equation for the scenario above is:
In the second statement Marie received an order of 4 trays of lasagna and 4 trays of garlic bread and so:
Now we cannot use the elimination method directly because equation 1 and equation 2 do not have any coefficients in common. However, we can eliminate "G" by first multiplying the top equation by 4 and the bottom equation by 3. We are doing this because those are the coefficients of the other equation, and thus will return a common value as such:
Equation 1:
Equation 2:
Now we can subtract equation 2 from equation 1 and eliminate the "G" variable as such:
By solving for L we obtain:
Therefore, one tray of lasagna is $24.95. Now that we know the value of "L" we can use any of our original equations to figure out what "G" is. I'll use the first equation and so:
And so the price of a tray of garlic bread is $12.75. So the answer is the price of lasagna = $24.95 and garlic bread = $12.75
