Answer:
<h2>∠DBE = 105°</h2>
Step-by-step explanation:
Angles on one side of a straight line always add to 180°.
Therefore we have the equation:
<em>combine like terms</em>
<em>subtract 20 from both sides</em>
<em>divide both sides by 4</em>
∠DBE = 3x - 15. Substitute:
Answer:
x = the flat fee = $1.5
y = fee per each letter sent = $0.7
Step-by-step explanation:
Let
x = the flat fee
y = fee per each letter sent
The equations
x + 35y = 26 (1)
x + 18y = 14.10 (2)
Subtract (2) from (1) to eliminate x
35y - 18y = 26 - 14.10
17y = 11.9
y = 11.9/17
y = 0.7
Substitute y = 0.7 into (1)
x + 35y = 26 (1)
x + 35(0.7) = 26
x + 24.5 = 26
x = 26 - 24.5
x = 1.5
x = the flat fee = $1.5
y = fee per each letter sent = $0.7
