Answer:
Hiro should have divided both sides of the equation by b
Step-by-step explanation:
Given the formula for area of a triangle (A) = ½bh, Hiro was expected to solve for h.
To find out where Hiro made a mistake, let's solve for h step by step as it ought to be solved.
Thus,
A = ½ bh
==>Multiply both sides by 2:
2*A = 2 * [½bh]
2A = bh
==>Divide both sides by b:
(2A)/b = (bh)/b
(2A)/b = h
h = (2A)/b
The mistake Hiro made was that he subtracted b from both sides of the equation instead if dividing both sides by b.
Hiro should have divided both sides of the equation by b
Answer:
see explanation
Step-by-step explanation:
Given
A = bh
a. substitute b = 6 and h = 5 into the formula
A = × 6 × 5 = × 30 = 15 units²
b.
Multiply both sides of the formula by 2
2A = bh, that is
bh = 2A ← divide both sides by b
h = = = = 8
c
Using
bh = 2A ← divide both sides by h
b = = = = 6
15% of 38.75 is approximately 5.81.
A 15% tip would be $5.81.
