The slope of CD is -3. Bc if it was 3 as in the answer above, then the so called "parallel" lines would intersect.
So you know that there are 51 states in the US. 49/51 are apart of the continental US.
To find that percentage, all we need to do is divide 49 by 51 and convert the decimal we get into a percentage.
49/51= 0.9607...
To convert this into a percentage, we multiply it by 100. This is the equivalent of moving the decimal point over two places to the right.
49/51= 96.07% of the states are part of the continental US
Does this make sense? Hope it helped!
Answer:
9 dollars
Step-by-step explanation:
Solve with a system of equations
Let adult tickets be a and student tickets be s
1. 8a + 13s = 176
2. 4a + 4s = 68
3. s = 17 - a
Equation 2 is friendlier, so let's divide all the numbers by 4.
a + s = 17
Equation is s = 17 - a
Substitute s in equation 1
8a + 13(17-a) = 176
8a + 221 - 13a = 176
221 - 5a = 176
5a = 45
a = 9
The price of an adult ticket is 9 dollars

Answer:
<h2>n < 43</h2>
Step-by-step explanation:
n + 19 < 62 <em>subtract 19 from both sides</em>
n + 19 - 19 < 62 - 19
n < 43
Answer:
3n
Step-by-step explanation:
Looking at other pairs, we know that the output is 3 times the input.
So, the output is 3n when the input is n
