I believe your answer is -220w-22
2-3(2w+1)=7w-3(7+w)
+7w -7w
2-3(9w+1)=-3(7+w)
+w -w
2-3(10w+1)=-3(7)
2-3(10w+1)=-21
-1(10w+1=-21
-21 +21
-22(10w+1)
-220w-22
Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters
Hope this helped!!
Answer:
63.5 in
Step-by-step explanation:
y2-y1/x2-x1
28.5-21/2.5-1 = 5
y=mx+b
21=5(1)+b
21-5= 16
b=16
y=mx+b
y=5(9.5) + 16
=63.5
