Answer:
Choice A ; Choice B
Step-by-step explanation:
x < 365
x ∈ ( -oo ; 365 )
Solutions :
x = 99
x = 361
Steps to my answer:
18x-9xy+12x
Add similar elements together, your answer comes out to be:
=30x-9xy

The distance is increasing at a rate that is the speed of the plane multiplied by the cosine of the angle between its flight path and the direct line to the radar station. That cosine is 4/√(3²+4²) = 4/5, so the distance is increasing at
440 mi/h × 4/5 = 352 mi/h
The answer is $45
Let's make the system of equations.
x - the cost of the car
y - the amount Matthew has
<span>Matthew currently has enough money to buy 45 toy cars:
y =45x
</span><span>If the cost of each car was 10 cents less, Matthew could buy 5 more cars:
y = (x - 10)*(45 + 5)
45x = (x - 0.10) * 50
45x = 50x - 5
5 = 50x - 45x
5 = 5x
x = 5 / 5
x = 1
y = 45x = 45 * 1 = $45</span>
Answer:
12
Step-by-step explanation:
The way to find the slope side of a traingle is
A^2+B^2=C^2 Next you substitute
5^2+B^2=13^2 Next simplify
25+B^2=169 Next use the subtraction property of equality
B^2=144 Next find the square root
B=12
Hope this helps :)
