She can buy 20 $1 items or 10 $2 items or a mixture of both.
Answer:

Step-by-step explanation:

M< 6 = m< 7 (vertical angles)
11x + 8 = <span>12x – 4
12x - 11x = 8 + 4
x = 12
so
m< 6 = </span>11x + 8
m< 6 = 11(12) + 8
m< 6 = 132 + 8
m< 6 = 140
m<4 = 180 - m<6
m<4 = 180 - 140
m<4 = 40
answer
<span>m<4 = 40</span>
Unfortunately, there's no diagram here! But the prism is described as "rectangular." Thus, the volume is simply (length)(width)(height) cubic inches. Multiply: (8 inches)(9 inches)(12 inches).
