Before getting to school, Keith has a few errands to run. Keith has to walk 5 blocks to the library, and 8 blocks to the store, before walking the final 4 blocks to arrive at school. If Keith has already walked 10 blocks, how many more blocks must he walk before arriving at school?

Joan had 228 bear stickers. Joan gave 57 stickers to Benny, 67 stickers to her sister and an additional 36 stickers to Mary. How many stickers does Joan still have?

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

d 600 because 15*10*2=300

300+300=600
