Add all of the numbers because they are like-terms (because they are all ounces)
he made 8 ounce servings, so 116/8 = 14.5 there are 4 ounces left
X-2 for x=-3
-3-2=-5, add dem negatives
Answer:
Step-by-step explanation:
The illustration is unclear. Is y the base of both triangles, or is it the base of the triangle on the right?
I'll assume that y is the base of the triangle on the right.
The triangle on the left is a 45-45-90 triangle. The lengths of the sides are in the ratio 1:1:√2, so the length of the vertical leg is 8/√2.
The triangle on the right is a 30-60-90 triangle. The lengths of the sides are in the ratio 1:√3:2.
The side opposite the 30° angle is 8/√2, so the side opposite the 60° angle is 8√3/√2 = 4√6, and the side opposite the 90° angle is 2×8/√2 = 8√2.
3x-(y/4)=11
subsitute
in (x,y) form
if (3,-8)
subsitute 3 for x and -8 for y
3(3)-(-8/4)=11
9-(-2)=11
9+2=11
11=11
(3,-8) is a valid soultion
try 4,4
subsittue 4 for x and 4 for y
3(4)-(4/4)=11
12-(1)=11
12-1=11
11=11
(4,4) is a valid solution
both are true so the answer choice is B, both are solutions
