Answer:
x=2/5
or
x=-22/5
Step-by-step explanation:
If Ciro's expression is equal to Gunther's expression x is equal to 2/5.
If Gerard's expression is equal to Gunther's expression x is equal to -22/5.
Your welcome!
6500 + 125.25t = 5292 + 200.75t
6500 - 5292 = 200.75t - 125.25t
1208 = 75.50t
1208 / 75.50 = t
16 = t
they both charge the same when using 16 tons
they both cost $ 8504
Answer:
<h2>radius = 8</h2>
Step-by-step explanation:
NOTE ================================
EQUATION OF A CIRCLE with center (a , b) and radius r :
(x - a)² + (y-b)² = r²
……………………………………………
x² − 14x + y² = 15
⇔ x² − 2×7x + 7² − 7² + y² = 15
⇔ x² − 2×7x + 49 − 49 + y² = 15
⇔ (x - 7)² − 49 + y² = 15
⇔ (x - 7)² + y² = 15 + 49
⇔ (x - 7)² + y² = 64
⇔ (x - 7)² + y² = 8²
Then radius of the circle is 8.
Angle 2 is congruent to angle 5 because they are vertical angles. Angle 5 is congruent to angle 9 because they are same-side interior angles. Angle 9 is congruent to angle 14 because they are vertical angles. Lastly, angle 14 is congruent to angle 15 because they are same-side interior angles. Therefore, angle 2 is congruent to angle 15.
