Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for A
A = 180° - (90 + 48)° = 180° - 138° = 42°
----------------------------------------------------------
tan48° = 
= 
Multiply both sides by a
a × tan48° = 18 ( divide both sides by tan48° )
a = 
≈ 16.2 ( to the nearest tenth )
-----------------------------------------------------------
sin48° = 
= 
Multiply both sides by c
c × sin48° = 18 ( divide both sides by sin48° )
c = 
≈ 24.2 ( to the nearest tenth )
<span>step 1 :</span> 3 • (x - 9) - 30 = 0
<span>Step 2 :</span><span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
3x - 57 = 3 • (x - 19)
<span>Equation at the end of step 3 :</span> 3 • (x - 19) = 0
<span>Step 4 :</span>Equations which are never true :
<span> 4.1 </span> Solve : 3 = 0
<span>This equation has no solution.
</span>A a non-zero constant never equals zero.
Solving a Single Variable Equation :
<span> 4.2 </span> Solve : x-19 = 0<span>
</span>Add 19 to both sides of the equation :<span>
</span> x = 19
One solution was found : <span> x = 19</span>

This is because in order to keep the ordered pairs a function, x cannot repeat. 1 is the only x that has nor repeated. Hope this helps mate.
Answer:
24 + p = 56
Step-by-step explanation:
Eva baked 24 cookies. Jamir baked p cookies. The total amount of cookies baked is 56. Another equation could be 56 - p = 24 . Or 56 - 24 = p
