Use y=mx+b , it will will help u!
Hi there, to solve this problem we have to do this, Add -4 on both sides, 4+-4+-3x=-8+-4. Now you should have, -3x=-12. Lastly, we divide each side by -3, which gives us x=4. Therefore, the answer is x=4. Hoped I helped. :)
Answer:
Y=3
Step-by-step explanation:
-8 times 3 equals -24
Answer:
75 miles
Step-by-step explanation:
Distance Traveled at first 60 min.
let distance be d1, speed be d1 and time be t1
d1 = ?
t1 = 60 min = 1 hr
s1 = 40mil/hr.
d1 = t1 * s1
d1 = 1 * 40
d1 = 40 miles
Part 2
distance = d2 = ?
speed = s2 = 70 mil/hr
time = t2 = 30 min = 0.5 hr
d2 = t2 * s2
d2 = 0.5 * 70
d2 = 35 miles
Total distance Traveled = d1 + d2
40 + 35 = 75 miles
