-18f - 34 - 14f = 11
-32f - 34 = 11
-32f = 45
f = -32/45
Simplify the fraction if needed!
Hope this helps, and please mark brainliest!
X is an exterior angle so it’s 35+58 which equals 93
<span>Dr. Graham currently has two acid solutions.
60% acid AND 20% acid </span>
Dr. Graham needs 30 L of a 50% acid solution
We set up 2 equations in which s = 60% acid and t = 20% acid
A) s + t = 30
B) .60s + .20t = (.50 * 30)
We multiply equation A by -.20
A) = -.20s -.20t = -6 then we add it to B)
B) .60s + .20t = 15
.40s = 9
s = 22.5
t = 7.5
So, she needs to mix 22.5 liters of 60% acid with 7.5 liters of 20% acid.

Answer:
Both leave at 4 pm . The next time they will leave at 5:20 pm
Step-by-step explanation:
Taking LCM of 16 and 10
16= 2*2*2*2
10= 2*5
LCM= 2*2*2*2*5= 80
1 hour = 60 mins
80/60= 1 hour 20 minutes
Both leave at 4 pm . The next time they will leave at 5:20 pm
Answer:
If he drove 3 more hours he would be driving 241 Miles for 11 hours
3 Hours = 81 Miles
Step-by-step explanation:
216 = 8 hours
216 / 8 = 27 Miles per hour
27 x 3 = 81 Miles in 3 hours
216 + 81 = 241 Miles for 11 hours
Hope this helped you :D
