1)A 2)B 3)B 4)A
not sure why the other person answer said that the answer to 1 is B. an equilateral triangle has all sides at the same length, so the statement is true.
Answer:
27.55
Step-by-step explanation:
The mean of a set of numbers is the sum divided by the number of terms.
So 49.7 + 15.8 + 22.7 + 15.1 + 32.2 + 39.1 +27.7 + 18.1 = 220.4
220.4 / 8 = 27.55
Answer:
15 years
Step-by-step explanation:
<u>Complete Question:</u>
<em>Ben is 4 times as old as Ishaan. 6 years ago, Ben was 6 times as old as Ishaan. How old is Ishaan now?</em>
<em />
Let Ben's age be "b" and Ishaan's age be "i"
Since Ben is 4 times as Ishaan, we can write:
b = 4i
Ben was 6 times as Ishaan, BUT 6 years ago, we setup the equation like shown below:
b - 6 = 6(i - 6)
Multiplying, we have:
Now, we replace b with "4i" and solve for i (Ishaan's age now):
Ishaan is now 15 years old
Step One: Plug in (x-1) for y in 2x-y = 0
Step Two: Distribute the negative
<u />
Step Three: Add like terms on one side of the equation
Step Four: Subtract 1 from both sides
Step Five: Plug x into one original equation (I chose y=x-1 but you can do either one)
That's the answer to the problem, x = -1, y = -2 (-1,-2)!
Hope this helps!
