Answer:
x=68
Step-by-step explanation:
We begin by setting up as a proportion. 99.2 and 112 ft are across from each other so we can put those as our numerators. Additionally 62 and (x+2) ft are across from each other so we can put those as denominators. Now we can set up our proportion and begin to cross multiply:
99.2/62 = 112/(x+2) is our equation. It might help you see it clearly to write it out as fractions. From here, we cross multiply.
When we do that, we get x=68
Answer:
59.11
Step-by-step explanation:
57.03 + 2.08=
59.11
Answer:
10 and 13
Step-by-step explanation:
Let the two numbers be p and q. p = (1/2)q + 8. p + q = 23. Substituting (1/2)q + 8 for p, we get (1/2)q + 8 + q = 23.
First, subtract 8 from both sides, obtaining (1/2)q + q = 15.
Next, mult. all terms by 2 to eliminate the fraction (1/2): q + 2q = 30.
Then 3q = 30, and q = 10. Then p = (1/2)(10) + 8 = 5 + 8 = 13.
The numbers are 10 and 13.
