Answer: x = 1
3x + 4 = 7
subtract 4 from both sides
3x = 3
x = 3/3 = 1
Answer:
Maggie
Step-by-step explanation:
So trevor drove 50.5mph bc 202/4
Maggie 330/6 = 55mph
Nev 412/8=51.5mph
Juanita 261/5= 52.2mph
First of all we will divide 8 by 2 to get the number of full practices in the morning, which is 4. Next divide 7 by 2 to get the number of practices in the afternoon. Although there is a remainder, that remainder is not a full practice session, so we only count the whole numbers which is 3.
4 + 3 = 7 full practice sessions.
Pythagorean theorem.
a^2+b^2=c^2
6^2+7^2=c^2
36 + 49 = c^2
85 = c^2
sqrt of 85 = 9.22
So the best answer would be C. 9
