Answer:
(-5,-3)
Step-by-step explanation:
In this case to find the solution you could use substitution. This way you can solve without changing the equation over again.
(b - 2) - 3b = 4
b - 2 - 3b = 4
-2b - 2 = 4
-2b = 6
b = -3
Plug back in to find value a
a = (-3) - 2
a = -5
Check your answer before submitting
(-5) - 3(-3) = 4
-5 + 9 = 4
4 = 4
Hope this helps
Answer: $86.83 is the total amount and $11.33 is the total of added tip
Step-by-step explanation:
Use the sine theorem:
sin(angle A) / length of side a = sin (angle B) / lenght of side b
Here:
angle A = 32°
length of side a = length from school to library = x
angle B = 110°
length of side b = 2.2 mi
Then, sin(32°) / x = sin(110°) / 2.2 mi
=> x = 2.2 mi * sin (32) / sin (110)
x = 1.24 mi
Therefore the answer is the option B. 1.2 mi
Answer: 33 and 28
Step-by-step explanation:
so, all we know is ? + ? = 61
if the larger number is 5 more than the smaller number, we can assume that..
33 + 28 = 61
