When calculating absolute value (like those questions above) you do whatever is in the absolute value bars first (if its just a number then.... just make the number positive, even if it is negative or already positive) and whatever answer you get inside those absolute value bars will ALWAYS be positive unless it's like -[4} then it's a negative number bcz the positive outcome that comes out of the absolute value bars gets multiplied by -1 (or just turned negative). So, for the first one you do 22+48=70 and -7--20=13 and then make the outcome of both of those positive and then subtract them from each other 70-13=57. For the second one you do 7+-33=-26 and 4+16=20 and make the outcome of both of those positive and then you add 26+20=46 and so and so on for the other problems.
Answer:
Toni pays 84000
Step-by-step explanation:
Data :
Joni books = 35
Joni price = 122500
Toni books = 24
Find price of single book
122500/35 = 3500
Toni prices if 24 books is
24 × 3500 = 84000
Answer:
The given equation will have two roots as +5i and -5i
Step-by-step explanation:
Shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function
The given equation is 
This clearly shows it will have complex roots, and since it is a quadratic equation it will have 2 complex roots
x = ± 5i
It will be false to say that -5i will be the only complex root to this equation.
The given equation will have +5i and -5i as its roots.
Lets verify
x = +5i
x = -5i
Answer:
10
Step-by-step explanation:
Let "a number" = x
4(x - 4) = 24
Isolate the x. First, divide 4 from both sides
(4(x -4))/4 = (24)/4
x - 4 = 6
Add 4 to both sides
x - 4 (+4) = 6 (+4)
x = 6 + 4
x = 10
10 is your answer for "a number"
