Answer:
Step-by-step explanation:
both angles must add up to 180 so
6x+12+3x+63 must =180
= 9x+75
9x+75=180
-75 -75
9x=105
x=11.66
meaning A is approximately 81.96
The vertex of a parabola is its highest or lowest point. Here, it is the lowest point, which happens right at the bottom of the U-shape—at (1, –4). Therefore, the answer is C.
Answer:
27 stuffed bears
Step-by-step explanation:
Erin: 55 Su: 15
Erin: 55-7=48 ( 7 will be kept for herself)
Erin and her sisters: 48/4= 12
Each sister besides Erin and Su have 12
Su: 15+12=27
Thus, Su will have 27 stuffed bears
X= 0.95424250 so to four it would be x=0.9542
Answer:
126.4 (rounded to the nearest tenth)
Step-by-step explanation:
53,558/100 = 67739/x
67739*100=53558X
6773900=53558X
6773900/53558=x
126.4070314=X
Use Arizonia as a reference index point. Since it is set at 100, you can put the median income over 100 is equal to California median income over x. Then solve for X.
