Answer:
37/9 pounds
Step-by-step explanation:
+ them together
Well since the only possible step to begin with is finding the square root of the entire equation, we are left with :
x+y-5 =√(30)
So from there we add 5 and subtract y to/from √30 and get :
x = √(30)-y+5
or
x = √(2)*√(3)*√(5)-y+5 (if the teacher or instructions preferred √(30) simplified)
One way of solving this is simply by substituting for each x in the table into each formula to see if you get the corresponding y in the table
so if x is 1,
then in the first equation -> y = 1-2(1) = y= 1-2 = -1
so right off the bat, we found the right equation
but essentially you should do it until you find the one that fits
Answer:
x= 2.5
Step-by-step explanation:
We can use ratios to solve
AB AD
------- = ----------
AC AE
X 5
------- = ----------
x+1 7
Using cross products
7x = 5(x+1)
Distribute
7x = 5x+5
subtract 5x
7x-5x = 5x-5x+5
2x= 5
Divide by 2
2x/2 = 5/2
x = 2.5
