Answer:
a=245 s=315
Step: Solve a+s=560 for a:
a+s=560
a+s=560(Add -s to both sides)
a=−s+560
Step: Substitute −s+560 for a in 8a+3s=2905:
8a+3s=2905
8(−s+560)+3s=2905
−5s+4480=2905(Simplify both sides of the equation)
−5s+4480=2905(Add -4480 to both sides)
−5s=−1575
−5s=−1575(Divide both sides by -5)
s=315
Step: Substitute 315 for s in a=−s+560:
a=−s+560
a=−315+560
a=245
The answer is 52
Cos0 = 16/26
Cos-1(16/26) = 0
0 = 52.02
Answer:
2.25 tons
Step-by-step explanation:
It is a conversion problem. The connection between ton and pound is in the following order:
1 pound = 0.0005 tons
By multiplying each side by 4500 we can easily find the answer of this problem:
4500 pounds = 2.25 tons

Answer: C) x = 13</h3>
====================================================
Work Shown:
We have a right triangle with legs a = 5 and b = 12. The hypotenuse is c = x which is unknown for now.
Use the pythagorean theorem to find x.
a^2 + b^2 = c^2
5^2 + 12^2 = x^2
25 + 144 = x^2
169 = x^2
x^2 = 169
x = sqrt(169) .... apply the square root to both sides
x = 13
