I do believe that it is the second one I’m not 100% sure but I’m pretty sure it is
10/1 = 43.5/x
cross multiply
10x=43.5
divide by 10 on each side
x = 4.35
it will take 4.35 minutes
Answer:
w = x = 36
Step-by-step explanation:
In the largest triangle, the longest side is x
The shortest side = 18
In the smaller triangle the longest side is 6
The shortest side is 3
You can set up a ratio
x/18 = 6/3 Divide the right side by 3
x/18 = 2 Multiply both sides by 18
18 *x / 18 = 2 * 18
x = 36
-7 = 1 + 2/3n
Subtract 1 from both sides:
-8 = 2/3n
Multiply both sides by 3:
-24 = 2n
Divide both sides by 2:
N= -12
