Answer:
5. B) 55
6. D) 15
Step-by-step explanation:
5.
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
Answer:
3 galllon one is $8 because it is the only thing that you can multiply by 3 to get 24
The 4 gallon one is $9 because it is the only number that you can multiply by 4 to get 36
Step-by-step explanation:
Answer:
2 15/26
Step-by-step explanation:
Make them both fractions and find a common demoninator. 8 1/13 = 105/13 and 5 1/2 = 11/2. A common denominator is 26, so 105/13 * 2 = 210/26 and 11/2 * 13 = 143/26. You then subtract the fractions to find out how much is left to walk, 210-143 = 67/26, or 2 15/26.
Answer:
y = 10
Step-by-step explanation:
substitute x = - 3 into the equation
(4 × - 3) + 2y = 8
- 12 + 2y = 8 ( add 12 to both sides )
2y = 20 ( divide both sides by 2 )
y = 10
