Answer:
there are 13 of them brother from another mother
The total cost of the camera is $268.26
A down payment of $12 was paid so he now owes $256.26
Every 6 months Emil has to pay:
256.26 / 6 = 42.71
Therefore, each moth, Emil has to pay $42.71
The domain is the input values, which would be the numbers that have the arrows pointing away from them.
This would be the 4 numbers in the oval on the left side.
The answer is B. {1,2,3,4}
Answer:
5. B) 55
6. D) 15
Step-by-step explanation:

One of the properties of a triangle is that the sum of angles in a triangle will always equal (180) degrees. One can apply this here, form an equation and solve for (x). Remember, a box around an angle indicates that the measure of the angle is (90) degrees.
90 + x + 35 = 180
Simplify,
125 + x = 180
Inverse operations,
x = 55

This triangle is a right triangle, as mention earlier, a box around an angle indicates that the angle measure is (90) degrees. One of the criteria of a triangle to be considered a right triangle is that it must contain a (90) degree angle. One of the properties of a right triangle is that it follows the Pythagorean theorem, the Pythagorean theorem states the following,

Where (a) and (b) are the legs or sides adjacent to the right triangle, and (c) is the hypotenuse or side opposite the right angle.

Simplify,

Inverse operations,
c = 15
