3/x = x/6
x^2 = 18
x = 3√2
answer
3√2 units
Answer:
8.39958×10(raised to power of eight)
First we have to know is that every number raised to zero is equal to one and every number raised to 1 is the same number.
So we solve the fractions.
When we divide by 1 we have the same number
16)
When we have numbers divided by 10 we run the decimal point to the left one position
20)
24)
Replace the informations you don't know with letters.
x = number of bags
y = number of sandwiches
7x + 3y = 22
3x + y = 8
Then solve the equations.
First, isolate the y in the second one like this :
y = 8 - 3x
then replace the y in the first equation with its worth from the second equation :
7x + 3(8 - 3x) = 22
solve for x, then replace the value in the equations to get the value of y
Answer:
-100-(-98)=-100+98=-2 then negative
