To write 25/4 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 25 by 4 what we write down as 25/4 and we get 6.25
And finally we have:
25/4 as a decimal equals <span>6.25</span>
Answer:
14
Step-by-step explanation:
We can make this and equation
x • y = 1260
x = 3y +48
Our equation is
(3y +48)y = 1260
We get y = 14
Answer:
21 AED
Step-by-step explanation:
W know the cost of each kind of meat
Chicken = 4 AED
Beef = 3 AED
We also know how much of each we will be buying
Chicken = 3.6 kg
Beef = 2.2 kg
Multiply each price of meat by its respective weight, then add the products together for you final answer.
4(3.6) + 3(2.2) = 21
Answer:
Step-by-step explanation:
Notice that the series: 1 - 3 + 9 - 27 +... clearly has powers of the factor 3 in its terms and it is also an alternate series (the terms alternate from positive to negative). The terms are positive for 
(even terms) , while the odd terms 
are negative. (so most likely there should be a factor (-1) in the common ratio.
We can then represent it with the following summation expression:
given that each of its first four terms are:
Answer:
(2,4).
Step-by-step explanation:
Graph of y = f(-x).
The values of x in f(-x) assume the values of -x in f(x).
For example, f(-2) in f(x) is f(2) in f(-x), and f(2) in f(x) is f(-2) in f(-x).
b) Write down the coordinates of the maximum point of the graph of y = f(-x).
In f(x), we have that x = -2. So in f(-x), it will be x = 2. y remains unchanged. So
(2,4).
