Lets use O to represent Merideth's age and X to represent Miles's age,
So what do we know? we know that miles is 3 years younger than twice merideth's age so 2(O)=X+3 and we also know that the sum of their ages is 24 O+X=24 using these equations we can input values until we find the values that work so if miles is 15 and meridith is 9 than 2(9)=15+3. 18=18
9+15=24 these values work for both equations so merideth is 9 and miles is 15
Answer:
How do you find the angle of a right triangle with 3 sides?
Step-by-step explanation:
Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).
Step 2 SOHCAHTOA tells us we must use Cosine.
Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.
Step 4 Find the angle from your calculator using cos-1 of 0.8333:
0.8km = 800m
On Sunday, Li ran farther. 80m farther
800m - 720m = 80m
Answer:
1/4
Step-by-step explanation:
C+a=166
a=166-c
5.3c+9.2a=1254.2
5.3c+9.2(166-c)=1254.2
5.3c+1527.2-9.2c=1254.2
5.3c-9.2c=1254.2-1527.2
-3.9c=-273
c=-273/-3.9
c=70
Hope this helps!
