Answer:
i hope its correct
Step-by-step explanation:
11x + 2y=68 ------------1
5x+y=13 ------------2
y= 13-5x. ------------3
put 3 into 1
11x +2(13-5x) =68
11x +26 -10x =68
x=42
put x =42 into 2
5(42) +y =13
210+y=13
y=13-210
y=197
First, we will find the value of k
We can do this by sybstituting y=24, x=6 in;
y=kx and then solve for k
24= k(6)
divide both-side of the equation by 6
24/6 = k
4 = k
k=4
Then when x = 5, we will substitute x=5 and k=4 in; y=kx and then solve for y
y= (4)(5)
y = 20
Answer:
2.3 < x < 8.7
Step-by-step explanation:
Given 2 sides of a triangle then the 3rd side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
5.5 - 3.2 < x < 5.5 + 3.2
2.3 < x < 8.7
Your answer is true , it can be stated by putting it into simplest form
Answer:
12 _3/4
