Answer: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.
Step-by-step explanation: <em>Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.
</em>
<em>
</em>
<em>Then divide the total number of cookies by the number of guests: 84 21 = 4. Each person would get 4 cookies.</em>
<em>
</em>
<em>This process can be modeled by the expressions 28(3) ÷ 21 and </em>
<em>28(3)
</em>
<em>21
</em>
<em>. This is because the fraction bar represents division.</em>
You would have to multiply 0.500(0.5) to 45 and you would get 22.5
Area of circle = πr²
Area of circle = π(4÷2)² = 12.57 cm²
Step 1: x²-15=2x
step 2: x²-2x-15=0
step 3: (x-5)(x+3)=0
step 4: x-5=0 or x+3=0
step 5: x=5 of x=-3
0.8 times 1200 is 960, which is the number of people when the theatre is 80% full.
