Answer:
$4.29
Step-by-step explanation:
An easy way to do this is to move the decimal point to the left one space.
So 42.87 would become 4.287
But since we are talking about currency, we only want two numbers to the right of the decimal point: 4.28.
And since we are rounding to the nearest cent, the 7 on the end means we round up by 1, making the final answer 4.29!
Answer:
BC = 34
Step-by-step explanation:
Given that ∠B = ∠C then the triangle is isosceles.
Thus AB and AC are congruent, that is
4x - 8 = 2x + 12 ( subtract 2x from both sides )
2x - 8 = 12 ( add 8 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
Hence
BC = 3x + 4 = (3 × 10) + 4 = 30 + 4 = 34
