Answer:
$8
Step-by-step explanation:
$40:15 gallons
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>:3 gallons
So first you say what did you do to 15 to get three?
15÷3= 5
Now you divide forty by five since that is what you did to 15 to get three.
40÷5= 8
Number 1 is twenty and number two is fifty six
Answer:
im busy so i cant right now
Step-by-step explanation:
Distribute the 1/4:
1/4(16x) + 1/4(20) - 7x
Do the multiplication:
1/4(16x) = 16x/4 = 4x
1/4 (20) = 20/4 = 5
Now you have:
4x + 5 - 7x = 0
Combine like terms (4x and -7x):
-3x + 5 = 0
Subtract 5 from both sides:
-3x = -5
Divide by -3:
x = -5/-3 = 5/3
Answer:
x= 5/3
The solutions for the quadratic equation are given as follows:
x = -1, x = 7/5
<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:
y = ax^2 + bx + c
The solutions are:
In which:

For this problem, the equation is:
5x² - 2x - 7 = 0.
Hence the coefficients are a = 5, b = -2 and c = -7, and then the solutions are found as follows:
The solutions are:
x = -1, x = 7/5
