Answer:
the first one is 1/2(53+47) = 1/2(100)=50
the second one 1/2(360 - 53 - 47) = 1/2(260) = 130
Step-by-step explanation:
THIS IS GOES FOR THE CIRCLE DIAGRAM
25x² + 4y² + 50x - 24y - 39 = 0
25x² + 50x + 4y² - 24y - 39 = 0
25x² + 50x - 39 = 0 4y² - 24y - 39 = 0
x = <u>-b + √b² - 4ac</u> y<u> </u>= <u>-b + √b² - 4ac</u>
2a 2a
x = <u>-50 + √(-50)² - 4(25)(-39)</u> y =<u> -(-24) + √-(-24)² - 4(4)(-39)</u>
2(25) 2(4)
x = <u>-50 + √2500 + 3900</u> y = <u>24 + √-576 + 624</u>

x = <u>-50 + 80 </u> y =<u> 24 + √16 × 3</u>

He answer is 7 because 6.974 take away the 7 and the 4 yhe 9 is higher than the 6 so the 9 makes the 6 round up to 7
Answer:
x +24= 59
$35
Step-by-step explanation:
Let $x be the amount Owen earned on Saturday afternoon.
Amount earned in the morning +amount earned in the afternoon= $59
Given that he earned $24 in the morning,
$24 +$x= $59
x +24= 59
x= 59 -24 <em>(</em><em>-24</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x= 35
Thus, Owen earned $35 on Saturday afternoon.
147 because 21 times 7 is 147
