Answer:
x = 1
Step-by-step explanation:
Given
5x - (4x - 1) = 2 ← distribute parenthesis by - 1 and simplify left side
5x - 4x + 1 = 2
x + 1 = 2 ( subtract 1 from both sides )
x = 1
The fraction of his farm which isn’t ruined is 11/18
<h3>Fractions and proportion</h3>
Fractions are written as a ratio of two integers. The given question will be solved using the method of proportion.
If Uncle Bill has planted fruits in the farm and 7/12 is watermelon, and 2/3 of the watermelon section is ruined from the storm, the fraction ruined from the storm is;
Fraction ruined from the storm = 2/3* (7/12)
Simplify to its lowest term to have:
Fraction ruined from the storm = 7/18
Determine the fraction of the firm that is not ruined
Fraction not ruined = 1 - 7/18
Fraction not ruined = 11/18
Hence the fraction of his farm which isn’t ruined is 11/18 if uncle Bill has planted fruits in the farm and 7/12 is watermelon.

Answer:
y = (10 * 0.2) ^ x
Y = (2)^x
Y = 2^x + 10
6.5 hours
Step-by-step explanation:
Y is the number of people at the school who have been infected with the flu. The 10 is the initial number of infected students which is a constant so it does not change. The 0.2 is the rate of increase, or 20%. The x exponent is the number of hours so that is a changing number. Your answer is 2 to the power of the number of hours which is x. Add ten after that to get your number. to get 100 people ill, it would take about 6.5 hours.
Answer:
{x,y,z} = {1,-1,-2}
Step-by-step explanation:
Problem 60) The only natural number is the number 62 (assuming the number is 62 and not some decimal value;it's impossible to tell because it appears to be cut off). Recall that the set of natural numbers is the set {1, 2, 3, 4, ...} which is synonymous with the set of counting numbers.
------------------------------------------------
Problem 62) Irrational numbers are numbers that we CANNOT write as fractions of whole numbers. In this case, pi is irrational and so is sqrt(17)
It is impossible to write pi as a ratio of two integers (in the form p/q where q is nonzero). The same applies to sqrt(17).
------------------------------------------------
Problem 64)
There are two nonnegative integers and they are: 0 and 62 (keeping with the same assumption made back in problem 60 above). All you do here is list whole numbers that aren't negative.
