Answer: y = 3
Step-by-step explanation:
4(-1)+8y=20
negative * positive = negative
-4+8y=20
add 4 on both sides to isolate 8y
8y = 24
divide each side by 8
y = 3
I don't see the recipe, but i would divide the number of quarts that the recipe shows it will make by 2, and it will give you the correct number, make sure that it is in the correct unit

Hey there!
x= # of gallons of the 35% acid solution
Equation- 0.5 gal (0.1) + x gal (0.35) = (0.5 + x)(0.15)
x= .125 gallons
Hope this helps!
A) Your primary concerns are the points B and E, so y> .5x+4 and y>or= x-4B) choose one or both points, and enter them into the equations. If the statements are true, then the equations work
for problem C So, any point in the shaded area, but not on the line, are valid points for Natalie's school
