Answer:
Step-by-step explanation:
14.3 + 21.1 + x = 50
35.4 + x = 50
x = 50 - 35.4
x = 14.6 <=== she biked 14.6 miles on the 3rd day
Answer:
x = 1
Step-by-step explanation:
Add 4 from both sides which you add to the zero. Then, combine like terms, 5x - 1x which is 4x. Divide 4 from both sides and it equals 1.
Since area is length times width, it would be the factors of the equation for the area.
X2+11x+28 factors into...
Length is x+7 so...
Width is x+4
Answer:
8
Step-by-step explanation

5(3-1)-2
Then using PEMDAS you would simplify that:
5(2)-2
10-2
