Answer:
34 degrees
Step-by-step explanation:
supplementary Angles are pair of angles whose sum is 180 degrees.
Given
Angle 1 =
4x + 6 degrees
Angle 2 = 38 degrees
Condition : angles are supplementary Angles
therefore
Angle 1 + Angle 2 =180
4x+6+38 = 180
=>4x+44 = 180
=> 4x = 180-44
=> 4x= 136
=>x = 34
Thus value of x is 34 degrees.
We know that 40$ is a constant and the number of texts sent (t) will change the price therefire we can plug it in the basic linear equation (p being the total price):
p= 0.2t + 40
Let x represent the total amount litters of solutions for 60% alcohol
15-x represent the total amount of litters of solutions for 35% alcohol, so:
0.6(x)+0.35(15-x)=0.5(15)
0.6x+5.25-0.35x=7.5
0.25x+5.25=7.5
Subtract 5.25 to each side
0.25x+5.25-5.25=7.5-5.25
0.25x=2.25
Divided 0.25 to each side
0.25x/0.25=2.25/0.25
x=9 liters
15-x
=15-9
=6 litters. As a result, she must use 9 litters of 60% alcohol and 6 litters of 35% alcohol to make 50% alcohol. Hope it help!
