Answer:
5 times
Step-by-step explanation:
Assume the height of the streetlamp to be x
If you make a diagram from the details given by the question you should find two pairs of similar sides, from which you can form the equation
Solving this gives the height of the streetlamp as 30 feet. Divide this length by the height of the man to get the number of times the streetlamp is taller.
Answer:
Her equation system is incorrect
Step-by-step explanation:
Remember that
1 dime=$0.10
1 quarter=$0.25
Let
x------> the number of quarters
y-----> the number of dimes
we know that
0.25x+0.10y=20.70 ------> equation A
x=10+y -----> equation B
Her equation system is incorrect, because in her second equation she exchanged the variables, using x instead of y and y instead of x.

We have been given a statement written by Galen which is
"If the sum of the digits in a number is divisible by 3, the original number is divisible by 3."
Now we need to select which statements are true regarding his work.
A: The hypothesis of the statement is "If the sum of the digits in a number is divisible by 3."
Answer:
TRUE
B: An equivalent statement is "If the sum of the digits in a number is divisible by 3, then the original number is divisible by 3."
Answer:
TRUE
C: The statement is not a conditional statement because it does not include both an "if" and a "then" clause.
Answer:
FALSE, I agree that it has not used the word "then" but meaning of the statement is in the form of if then clause.
D:The statement can be proven true or false.
Answer:
TRUE, As you can take some example of any random number to test that.
E:The conclusion of the statement is written before the hypothesis.
Answer:
FALSE.
