Answer:
The answer is 8
Step-by-step explanation: Use the KCF method.
Keep the first number, change the second sign into multiplication, and flip the numbers on the third part, so 4/1. Now multiply 2 and 4.
Distance = speed * time
for curtis d = st = 6t (where t is the time that he walks)
sean walks 20 seconds longer than curtis so we have the equation
d = s(t+20) = 5(t+20)
as the distances are the same we have
So sean has walked 100+20 = 2
6t = 5(t+20)
6t = 5t + 100
t = 100
so Sean walks 120 seconds when they had both walked the same distance.
Answer:
Step-by-step explanation:
r+58
Let r=3
3+58
61
Answer:
x =
Step-by-step explanation:
The question states that it is the square root of the sum of both n and 6. That means n and 6 are added first before square rooted. Between B and C, choose the answer that has the parenthesis around x and 6, like (x + 6).
Answer:
15+2i
Step-by-step explanation:
Hi there!
We are given the following expression:
(7-4i) + (8+6i)
And we want to write it as a complex number in standard form
Standard form is <u>a+bi</u>, where a is the real part of the number and bi is the imaginary part of the number.
We can open up the parentheses on the expression
7-4i+8+6i
Now combine the like terms (add 8 and 7 together, then add -4i and 6i together)
<u>15+2i </u>
The complex number is now in standard form
Hope this helps!
