Answer:
a. let x be the number of apples and let y be the number of oranges
x + y = 60
x = y + 12
b. Apples: 24 Oranges: 36

Step-by-step explanation:
just draw the triangle but flipped over the red line
sorry for the bad drawing
Answer:
16 ft
Step-by-step explanation:
If you connect points A and C with a straight line, you will have a right triangle with hypotenuse AC (radius), shorter leg 1/2 of CD and the longer leg 1/2 of AB.
AC = radius = 10 ft
1/2 CD = 1/2 of 12 = 6 ft
So we can use Pythagoras' Theorem to find the length of the longer leg of the right triangle:
6² + b² = 10²
36 + b² = 100
b² = 100 - 36
b² = 64
b = √64 = 8
As b = 1/2 AB, then AB = 2 x b = 2 x 8 = 16 ft
Answer: 26
Step-by-step explanation:
Let the tens digit=x
and units digit=y
Hence sum x+y=8…………(i)
Number =10x+y
Number formed by reversing the digits =10y+x
(10y+x)=(10x+y)+36 i . e. 9y-9x=36
Or y=x+4…………..(ii)
Adding (i) and (ii) gives 2y=12
Hence y=6
hence from (i)
x=8-y
8–6 = 2
hence Number =26
