Answer:
Let the number be n.
3n - 4= -15
3n= -15+4
3n= -11
n= -11/3
n= -3.67 or n= -3 2/3
Step-by-step explanation:
Bring over 4 to the RHS of the equation and divide the RHS by 3.
Answer:
The inequality would be $49 + g is less than $55
Step-by-step explanation:
I think that g would be 1 because that would make the bill $52 and it says that he wants to keep the bill under $55 not the same as $55
If it has real zeros at x=3 and 7, the factors of f(x) are:
(x-3)(x-7) so f(x) is
f(x)=x^2-10x+21
Answer:
The original cost was 20 dollars.
Step-by-step explanation:
$12 represents 60% of the original price.
Set up a proportion
Cross multiply Reduce 100/100 to 1
60/100 * x = 12 * 100/100
Multiply by 100
60/ 100 * x = 12
Divide by 60
60x = 12*100
60x = 1200
60x/60 = 1200/60
x = 20 dollars.
