We can solve x through simple algebra.
x + 5 = 2
x = 2 - 5
x = -3
x - 10 = 22
x = 22 + 10
x = 12
x - 27 = 8 + 10
x - 27 = 18
x = 18 + 27
x = 45
-11 + x + (-48) = 25
-11 + (-48) + x = 25
-59 + x = 25
x = 25 + 59
x = 84
x - (-16) = 12 + 13
x + 16 = 25
x = 25 - 16
x = 9
Tip: As you can see, the number sign changes as they shift from left to right (ex. -59 to +59).
Answer:
A = 41.41
Step-by-step explanation:
Since this is a right angle, we can use trig functions
cos A = adjacent/ hypotenuse
Cos A = 6/8
Taking the inverse cos of each side
cos ^ -1 ( cos A) = cos ^-1 ( 6/8)
A =41.40962211
Rounding to the nearest hundredth
A = 41.41
15 cards = 9$
1 card = (9/15)$
12 cards = 9/15 * 12
= 108/15
= 7.2$
They cross each other at (5,2)
