B. Kayla walks 23 4/5 miles in 7 days, the reason is because there are 7 days in a week and it says, "Kayla walks 3 2/5miles each day! (KEY WORK. EACH DAY) so since there is only 7 days in a week than the answer is B. If I am wrong please correct me. Hopefully this helps!
Answer:
x + y ≥ 3
x + y ≤ 3
Step-by-step explanation:
In the picture attached, the problem is shown.
The solution to the system:
x + y ≥ 3
x + y ≤ 3
is the line x + y = 3
In order to get a solution to a system of inequalities that is a line, we need the same equation on the left (here, x + y), the same constant on the right (here, 3), and the ≥ sign in one inequality and the sign ≤ in the other one.
First, you know that 3/4 = .75. Now we can distribute. multipy -10*.75. Then multiply .75*2/5. Add those two answers together to get your final answer.
Calculate the lengths of the sides of the triangle:
The triangle has three different sides, so it's a scalene triangle.
Now if c is the longest side of the triangle, and a and b are the shorter sides, then:
- if , the triangle is right
- if , the triangle is acute
- if , the triangle is obtuse
The longest side is 5.
The square of the longest side is equal to the sum of the squares of the shorter sides, so it's a right triangle.
The triangle is a right scalene triangle.
