Answer:
It is 5. I got it right on khan academy! Thanks for the answer!
Step-by-step explanation:
Let's do this in steps, show your work!
<u>#1. We need to move all terms to one side.</u>
<u>x^2 - 7x = 0</u>
<u>#2. Then factor out the common term x.</u>
<u>x(x - 7) = 0.</u>
<u>#3. Simplify to get..</u>
<u>x = 0, 7.</u>

Answer:
Step-by-step explanation:
Set up an equation, where x is the number of gallons of 60% antifreeze solution.
Represent the percentages of antifreeze with decimal values.
0.6x + 0.3(80) = 0.5(x + 80)
Simplify and solve for x:
0.6x + 24 = 0.5x + 40
0.1x = 16
x = 160
So, you have to mix 160 gallons of a 60% antifreeze solution
Answer:
the answer is a. 147
Explaination:
A triangle always has a sum of 180°.
We already have the angle of two sides give.
10° and 23°
To find the last missing side, you add 10° and 23°, and minus the result from 180°.
10+23= 33
180-33 = 147
