Answer:
Step-by-step explanation:
2.82191696 ounce in 80 grams.
N=3p and d=p-2 we are also told that:
p+n+d=110 using n and d from above we get:
p+3p+p-2=110
5p-2=110
5p=112
p=112/5
Which is not an integer...are we sure there is no typo in the question...
There are 3 times as many nickels as pennies
There are pennies-2 dimes
And the total is $1.10
Just checking, because something is off...
4x+3y=1 2x+5y=11
We'll need to use system of equations for this one.
4x+3y=1
3y=1-4x
y=-4/3x+1/3
2x+5y=1
5y=1-2x
y=-2x/5+1/5
Set these two equations equal to each other and solve for x.
-2x/5+1/5=-4/3x+1/3
x=1/7
Then plug x in to solve for y.
y=-2(1/7)/5+1/5
y=1/7
Answer:
Step-by-step explanation:
That's a complex expression, let's simplify it, step by step, off the start, we'll simplify the 55/11:
Then we'll simplify the x's and y's:
Let's split the square root in two and solve the bottom part:
The solution is then:
pretty sure its E
just substitute x and z for a and c
