Lets make x equal the the age of the younger man and y equal the age of the older man.
You are given x+y=76 and you can make the equation 2x+16=y since we are told that the older one is 16 more than twice the age of the younger one. Since we have 2 equations and with the same variable and one has y already written in terms of x (y=2x+16) i will use substitution and make the given equaton all in terms of x.
x+(2x+16)=76 (solve this for x)
3x+16=76
3x=60
x=20
Then you can solve for y using the equation the equaion x+y=76 since we now know x=20.
20+y=76
y=56
Second equation is y=2x+16 (can also be written as y-2x=16)
x=20
y=56
I hope this helps. If anything is unclear or you just want further explanation please let me know in the comments.
Multiply the 3 dimensions to find the volume, then find 4/5 of the volume by multiplying 4/5 by the volume.
12x5=60
60x20=1,200
I'm gunna convert the 4/5 to decimal to make it easier.
1,200x0.8=960
So there is a total liquid volume of 960(I'm assuming it's ounces).

Answer:
Option A
Annette picked 50 roses from the garden
Step-by-step explanation:
Let us understand the problem, designating letters to represent unknown quantities.
Let the total number of roses = x
20% of the roses were red means that 20% of x = red
Since the number of red roses = 10,
we will have that 20% of x = 10
mathematically, we will have
hence, Annette picked 50 roses from the garden
