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
18 is 6+n. The other one is 60 because n=60 and 60+6=66. 66 represents Chang's height.
Answer:
x° = 131°
Step-by-step explanation:
The two marked angles are on opposite sides of the transversal, so they are called "alternate" angles. They are both between the parallel lines, so they are called "interior" angles.
In this geometry, <em>alternate interior</em> angles are congruent. They have the same measure. x° = 131°.
