Ben gets 5 more presents than his naughty little sister Gwen this holiday season. If together they receive 21 presents, how many
1 answer:
9514 1404 393
Answer:
Step-by-step explanation:
The given relations give rise to two equations:
b = g + 5
b + g = 21
Using the first to substitute for b in the second, we have ...
(g +5) +g = 21
2g = 16 . . . . . . . subtract 5
g = 8 . . . . . . . . . divide by 2
b = 8 +5 = 13
Ben got 13 presents; Gwen got 8.

c is the answer cuz a is a straight line of dots b is a no solution plot and d is a poitive plot
The product of 5 and n is written as 
.
Two less than this product is 
< ABC is a straight angle
no right angles
no complimentary angles
< ABD and < DBC are supplementary angles
(3,-1)? i believe that's what it would be
3/8 + 3/5 = <u>39/40</u> and 39/40 Can't be <em>simplified</em>
