To solve this, you must find the initial weight of the cucumber. To do this, you must divide the weight by the percentage of water and multiply it by 100.
(21/92)×100=22.83lbs.
Then, you multiply it by 85% and divide it by 100. Or simply multiply it by 0.85.
22.83×0.85=19.41lbs.
Answer:
4x^2 -5x -2
Step-by-step explanation:
= 5x^2 -3x -7 -x^2 -2x +5
= (5 -1)x^2 +(-3 -2)x +(-7 +5)
= 4x^2 -5x -2
4x-6= 22
Move -6 to the other side.
Sign changes from -6 to +6.
4x-6+6= 22+6
4x= 22+6
4x= 28
Divide by 4 for both sides
4x/4= 28/4
x= 7
Answer : x= 7
The domain of a function is defined as the set of values of x that will give out a real value of y, a "real" number is basically a number that can be expressed as itself instead of as a symbol or a calculation, for example -4 would be a real number as we can simply express it as -4, however √-4 would not be a real number as it would be expressed as 2i. For the function y=25-x all values of x will result in a real number therefore we say domain of f(x) is x∈R, or simply saying "the domain of the function y=25-x is all real values of x" will probably suffice.
