4 bowls of pasta would be served for twelve people.
4×3=12
12'000×1.5 I think might need to multiple your answer by 4 yet
Answer:
Step-by-step explanation:
The difference of two squares may be represented by the formula: a^2-b^2,
which can be factored as (a+b)(a-b)
A perfect square trinomial may be represented by the formula: a^(2)-2ab+b^2 or a^(2)+2ab+b^2, depending on the sign of b
if b is negative: use the formula a^(2)-2ab+b^2, which can be factored as (a-b)*(a-b) or (a-b)^(2)
if b is positive: use the formula a^(2)+2ab+b^2, which can be factored as (a+b)*(a+b) or (a+b)^(2)
<span>4x+7y=51
Plug in </span><span>y=5::
4x+7(5)=51
Simplify:
4x+35=51
</span>
<span>4x+35-35=51-35
4x=16 (÷4)
x=4
Done :)
