Answer:
b = 4
r = 3
Step-by-step explanation:
r + b = 7
solve for 'r' to get r = 7-b
now substitute '7-b' for r in the second equation:
3.75(7-b) + 2.75b = 22.25
26.25 - 3.75b + 2.75b = 22.25
-b = -4
b = 4
r = 3
3(5 + 6)
15 + 18 is your answer
Distribute the 3 to both 5 and 6
3 x 5 = 15
6 x 3 = 18
15 + 18 is your expression
hope this helps
4 3/10 would be the answer

Answer:
.<em><u>O</u></em><em><u>P</u></em><em><u>T</u></em><em><u>I</u></em><em><u>O</u></em><em><u>N</u></em><em><u> </u></em><em><u>A</u></em><em><u>:</u></em><em><u>2</u></em><em><u>0</u></em><em><u>°</u></em>
SINCE THE BOTH SIDE OF LINE IS PERPENDICULAR
THEREFORE,90°
THEREFORE,
4X-10+X=90.
5X-10=90
5X=100
X=20°
So remember that (a/b)(c/d)=(ac)/(bd)
convert to imporoper number for easy
4 and 1/4=4+1/4=16/4+1/4=17/4
2 and 2/3=2+2/3=6/3+2/3=8/3
length times base=17/4 times 8/3=
(17 times 8)/(4 times 3)=
136/12=
34/3=
33/3+1/3=
10+1/3=
10 and 1/3 square yards
area is 10 and 1/3 square yards
