Answer:
19 bears, 38 boxes of candy.
Step-by-step explanation:
We can use a system of equations (b = # of bears, c = # of candy boxes):
<em>b + c = 57, 8b + 6c = 380</em>.
We can use substitution by isolating b in the first eq.: <em>b = 57 - c</em>, then substitution b with 57 - c in the second eq.: <em>8(57 - c) + 6c = 380</em>.
Then, we solve: 456 - 8c + 6c = 380, 76 = 2c, c = 38 candy boxes.
Finally we plug in 38 for c in the first eq.: b + 38 = 57, b = 19 bears.
If x is the amount of time Gillian takes,
1/10 - 1/x = 1/25
Therefore, the answer is A
Answer:
13.
<S=½(arc TQ- arc TR)=½(143-71)=36°
14.
<E=½(arc DG- arc DF)=½(169-59)=55°
15.
arc PR=180-62=118°{sum of opposite angle of quadrilateral in circle is supplementary)
16.
arc TR =180-47=133°
again
arc T?R=360-133=227°
17.
62+38x+4=180
38x=180-66
x=114/38
x=3
