Hey there!
Let's create a systems of equations using x and y.
4x+3y=15
3x-2y=7
We need to solve this using elimination. First, we need to multiply the first equation by 2/3 so that we can cancel out the y's when combining our equations.
2 2/3x+2y=10
3x-2y=7
Now we combine the equations...
5 2/3x=17
x=3
Now we can plug our x into the first equation to find y.
12+3y=15
y=1
Our numbers are 3 and 1.
I hope this helps!
8
Because 16 ounces is a pound half of 16 is 8, 8 ounces is half a pound. :)
The answer is A 18 inches
8<-5x+20 is one possible answer. it depends on how they are writing it. you need to do the distributed property.
