Answer:
t= -1
Step-by-step explanation:
where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
cross multiply:
1(t -6)= 7(-1)
t -6= -7
+6 on both sides:
t= -7 +6
t= -1
Answer:
3.25, I don't know, I'm in like 1st grade
Step-by-step explanation:
Number of females = f
Total number of people in audience = n
0.4n = f
f + (f+ 100) = n
2f + 100 = n
Find n:
f = 0.4n --> Replace f with 0.4n in the equation 2f +100 = n
2(0.4n) + 100 = n --> Multiply out the brackets
0.8n + 100 = n --> Subtract 0.8n from both sides
100 = 0.2n --> To get n, multiply both sides by 5
n = 500
There were 500 people in the audience.
7/8 of a cup. If you add 1+1 and then take away 1, you still have 1.
