Answer:
because M is the centroid of the triangle
=> PM = 2AM
<=> AM = PM/2 = 10 /2 = 5
=> AM = 5
Answer:
x = 1/3
Step-by-step explanation:
8x –3(5x–2)=7–10x
Distribute
8x - 15x +6 = 7-10x
Combine like terms
-7x + 6 = 7- 10x
Add 10x to each side
-7x +10x+ 6 = 7- 10x+10x
3x+6 = 7
Subtract 6 from each side
3x+6-6 =7-6
3x = 1
Divide each side by 3
3x/3 = 1/3
x = 1/3
Answer:
a)64
b)96
Step-by-step explanation:
For this we calculate the number of rows, 32, as 2+3 is 5, and 160/5 is 32. Then we know that there are 32 rows, and in each row are 2 left seats and 3 right seats, so we multiply 32 by both numbers for the answers.
Answer:
PQ = 16
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° = 
, then
cos60° = 
= 
= 
= ( cross- multiply )
PQ = 8 × 2 = 16
