Answer: The height of building is 311 feet and the height of statue is 15.6 feet.
Step-by-step explanation:
Let the height of the building be 'b' and the height of the statue be 'g'.
Then according to the question, we get the following equation
Now, add both the equations, we get
Substitute the value of b in equation (2), we get
Hence, the height of building = 311 feet and the height of statue =15.6 feet.
m = the number of miles
30 + 0.18m ≤ 75
[They charge $30 plus $0.18 per mile(m), she can spend no more than $75. So $75 is the maximum/most she can spend, she can't spend over $75.]
Your answer is C
Now you need to find the solution of the inequality in order to graph it.
30 + 0.18m ≤ 75 Isolate "m". Subtract 30 on both sides
0.18m ≤ 45 Divide 0.18 on both sides
m ≤ 250 [this means that she can drive 250 miles on $75]
Next you need to graph it on a number line.
When the sign is ≤ or ≥, the dot is filled in
When the sign is < or >, the dot is an open circle/not filled in
m ≤ 250 [m is less than or equal to 250, so m can be 250 or any number less than 250]
The graph shows that she can only drive 250 miles or less on $75
