For No. 13 you need to calculate the distance each girl travels and compare to see whose distance is greater. The formula for distance is rate x time or d=rt. The rate is just how fast they consistently go.
Mia
d = r x t
d = 14 x 3/2
d = 21 miles
Chloe
d = r x t
d = 35 x 3/4 (btw 3/4 is just 45/60 simplified)
d = 105/4 = 26 1/4 miles
Final Answer: Chloe traveled further
For No. 14 we will recalculate Mia's distance but replace 1/5 hours with 2 hours because it says she will bike 30 minutes after Chloe had stopped. Afterwards we will compare Mia's new distance with Chloe's old distance.
Mia
d = r x t
d = 14 x 2
d = 28 miles
Final Answer: Yes Mia would be able to catch up to Chloe, and even surpass her in 30 minutes if Chloe stopped.
Answer:140
Step-by-step explanation: 7x+4=13x-8 SOLVE FOR X, x=2, SOLVE EACH SIDE, JH=18, HK=18, KI=IL, GL=GJ, JH=HK, SO LI IS 15 SINCE KI IS 15, 52-15=37, LG=37, GJ=37. 18+18+15+15+37+37=140
7. 10 times negative 1 is -10
4.5 times -10 is 4.50
The answer is B. If you write down the values of X and Y you’ll find out that the right answer is B.
