The answer is 113 degrees because it’s supplementary you know you have to subtract it from 180 so 180-67=113
Answer:
x = 4
y = 12
Step-by-step explanation:
-3x - y = -24
y = 3x
Substitute for y in the first equation
-3x - (3x) = -24
-6x = -24
Divide by -6
x = 4
y = 3(4)
y = 12
<span>180 square yards is the answer because 18x10=180</span>
Let x=volume of 18% solution.
Use formula c1v1+c2v2=cv
c1=18%
c2=40%
c=20%
v=10 L
v1=x L
v2=10-x L
Apply formula
0.18x+0.40(10-x)=0.20(10)
expand
0.18x+4-0.40x = 2
solve
4-2=0.22x
x=2/0.22
=100/11
=9.091 L (to 3 decimal places)
Answer: 9.091 L of 18%, and (10-9.091)=0.909 L of 40%
Check:
c1v1+c2v2=0.18(9.091)+0.40(0.909)=2
cv=0.2*10 = 2 ok
