Most real number arithmetic is pretty vacuous

That's about as good a way as possible to write this particular real number. But it's far from the only way.

so

Sometimes you can factor something out and you have a common radical:

But most of them are vacuous,

Answer:
76
Step-by-step explanation:
let the number be x
Then 16 + x/-4 = -3, so
x/-4 = -16-3 = -19 (add -16 on both sides)
x = -4*-19 = 76 (multiply by -4 on both sides)
Divide 108 and 72 by twelve and you get 9 and 6 which all you have to do it multiply together
Answer:
m = 55/8 = 6.875
Step-by-step explanation:
Step by step solution :
Step 1 :
7
Simplify —
8
Equation at the end of step 1 :
7
6 - (m - —) = 0
8
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 8 as the denominator :
m m • 8
m = — = —————
1 8
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Answer:
5 pounds of coffee
Step-by-step explanation:
Let the number of pounds of coffee bought be 'x'.
Given:
Value on gift card = $90
Value of coffee per pound = $8.09
Money left after buying coffee = $49.55
Now, using unitary method,
1 pound cost = $8.09
∴ 'x' pounds cost = 
Now, Money left = Total money on gift card - Cost of coffee.

Therefore, Lashonda bought 5 pounds of coffee.
