A = amount of adult shirts sold
c = amount of child shirts sold
140 = 4a + 2c
D & F
Step-by-step explanation:
D scale because all sides are different lengths
F obtuse because one angle is greater than 90 degrees
Look up definition of the other properties and you will see they don't apply
Answer:
to the nearest tenth
Step-by-step explanation:

Answer:
16 units
Step-by-step explanation:
volume of a rectangular prism formula: b*h=v
b=64
v=1024
so
64h=1024
divide both sides with 64:
h=16
Hope this helps!
Answer:
y=29
Step-by-step explanation:
Since the angles are across a vertex from one another, they are congruent and equal. You can also see this by reflecting or folding it in half through the vertex. They will be the same. This means we can write the following equation and solve using inverse operations:
4y-8=79+y
4y-y-8=79+y-y
3y-8=79
3y-8+8=79+8
3y=87
y=29
