The answer <span>5 was added to each side.
</span>
x² + 5x + 126 = x² + 17x + 66
____
Subtract x² from both sides:
x² + 5x + 126 - x² = x² + 17x + 66 - x²
5x + 126 = 17x + 66
126 - 66 = 17x - 5x
60 = 12x
x = 60/12
x = 5
Thus, <span>5 was added to each side.</span>
We have to find two fractions which have a sum of - 7 /36.
5/9 + ( - 3/4 ) =
= 5/9 - 3/4 =
= (5*4)/(9*4) - (3*9)/(4*9)=
= 20/36 - 27/36 = - 7/36
Answer:
C ) - 3/4 and F ) 5/9
Answer:
$12.95 is the final cost for the oranges
$12 is the cost for apple
Step-by-step explanation:
The final cost for the orange is
30/100 x 18.50
=5.55
18.50-5.55
=$12.95
Answer:
-22 ≤ temperature(F) ≤ 266
Step-by-step explanation:
Given that,
The label on the car's antifreeze container claims to protect the car between -30C and 130C.
Formula to convert Celsius temperature to Fahrenheit
<h3>C = 5/9 (F - 32)</h3><h3>9C/5 = (F - 32)</h3><h3>9C/5 + 32 = F</h3><h2>F = 9C/5 + 32 </h2><h3>1)</h3>
-30C = ?F
F =9(-30)/5 + 32
F = -22
<h3>2)</h3>
130C = ?F
F =9(130)/5 + 32
F = 266
The inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car is
<h3>-22 ≤
temperature(F) ≤ 266</h3>
