Answer:
Step-by-step explanation:
-3x+10=21
-3x=21-10
-3x=11
x=11/-3
x=- 11/3
2 oranges cost $2 . $9 - $2 = $7
then 12 apply of Lisa and 6 apples of Jeremy
= 18 ÷ 7 = 2.57. $2.57 for 6 apples
2.57 ÷ 6 = 0.43 each apple
180 degrees - 115 degrees = 65 degrees
65 degrees + 90 degrees = 155 degrees
180 degrees - 155 degrees = y
Y= 25 degrees
4 I think is the right answer but I’m not sure so sorry if u get this wrong
Perimeter = 30 inches
Length = 3x
Width = X
P = 2L + 2W
30 = 2(3x) + 2(X)
30 = 6x + 2x
30 = 8x
30/8 = 8x/8
3 6/8 = 3 3/4 = X
X = 3.75 inches
The width is 3.75 inches and red length would be 3 times as much or 3(3.75) = 11.25 inches.
