Answer:
B.
Step-by-step explanation:
x = small box
(small box + 5 ounces) = large box.
B shows:
x + (x + 5) = 27
Small box + (small box + 5 ounces) = 27 ounces.
Small box + large box = 27 ounces.

Why A and C are incorrect.
A describes:
x + 5x = 27
Small box + 5 multiplied by small box = 27
(5 multiplied by small box is equivalent to 5 small boxes.)
Small box + 5 small boxes = 27
C describes:
x + 5 = 27
small box + 5 ounces = 27
Large box = 27
(We know that a small box + 5 ounces is a large box)
The triangle is acute. Since all triangles have 180 degrees, you can find the third angle by subtracting the sum of the other angles from 180.
180 - (25 + 87) = third angle
180 - 112 = third angle
68 = third angle
Since all three angles are less than 90 degrees, it is an acute triangle.
The answer is c because you only need student three and one only
Im not an expert or anything, but i think for the innequality, i would say

as far as the amount of people she can invite, do 500-100=400 because of the setup fee, then, to find how many people she can invite. 400÷6.50 which leaves you with the highest amount of people she can invite without going over budget, as 61.
