Answer:
b. 3 = 3/1
c. -4 = -4/1
Step-by-step explanation:
An integer can be written as a rational number with a denominator of 1. The denominator can be anything else, too, in which case the numerator must be multiplied by that same value.
__
b. 3 = 3/1 = 6/2 = 27/9
__
c. -4 = -4/1 = 8/-2 = -12/3
Based on the definition of the diagonals of a rhombus, m∠AED = 90°.
<h3>What are the Diagonals of a Rhombus?</h3>
A rhombus has two diagonals that bisect each other at right angles, that is they are perpendicular to each other.
Angle 90 is formed at the intersection of the two diagonals of a rhombus.
In rhombus ABCD, ∠AED is formed at the intersection of the diagonals of the rhombus.
Therefore, based on the definition of the diagonals of a rhombus, m∠AED = 90°.

Step-by-step explanation:
210 ÷ [ 5 + 16 ÷ 2 { 6 - 18 ÷ ( 7 + 2 ) } ] - 15
210 ÷ [ 5 + 16 ÷ 2 { 6 - 18 ÷ 9 } ] - 15
210 ÷ [ 5 + 16 ÷ 2 { 6 - 2 } ] - 15
210 ÷ [ 5 + 16 ÷ 2 { 4 } ] - 15
210 ÷ [ 5 + 16 ÷ 8 ] - 15
210 ÷ [ 5 + 2 ] - 15
210 ÷ 7 - 15
30 - 15

Answer:
When we have a discount of X% of the original price, the new price is calculated as:
New price = (original price) - (original price)*(X%/100%)
In our case, let's define:
P = original price of the fishing pole
f = price of the fishing pole after the discount
X% = 20%
Then the equation for the price of the fishing pole is:
f = P - P*(20%/100%) = P - P*0.2 = P*(1 - 0.2) = P*0.8
f = 0.8*P
This means that the price after the discount is 0.8 times the original price.
