Answer: B) a + c = 10
8a + 5c = 59
Step-by-step explanation:
We know that 10 total people went, so the first equation has to be equal to 10. The total was $59, so the second equation should be set equal to $59. Now that the second equation is for cost, we must make it 8a + 5c to represent the cost of the adult and child tickets which are $8 and $5, respectively.

Circumference of the circle:
- C = 2πr
- C = 2*3.14*3² = 56.52 km
<u>The length of the 75° arc:</u>
Answer:
36 cm²
Step-by-step explanation:
- cos A= (`sqrt(b)` + `sqrt(c)` - `sqrt(a)`)/(2bc)
⇒c ≈ 5 cm
Sabc= (1/2)bcsin A ≈ 36 cm²
Answer is 10
Scale factor is 2.5 (30/12)
So you have to do 4 multiplied by 2.5 to get x on the bigger shape.
Answer:
Step-by-step explanation:
1.Rewrite the equation as
(x−h)^2 = f(x)
2. Take the square root of both sides of the equation to eliminate the exponent on the left side.
x − h = ± √f(x)
3. The complete solution is the result of both the positive and negative portions of the solution.
