Answer:
1)7 2/8
2) 4 1/2
3) 7 2/4
4) 4 3/5
5) 7 1/9
6) 3 2/8
I will add more answers once I add this answer.
Step-by-step explanation: 1) you divide the top number by 8 then you will get 7 with a remainder of 2. 7 is the whole number and 2 will be on top of the fraction. do the same with all other problems.
-2x^2 + 5x -3 =0
Find the discriminate:
In the given formula a = -2, b = 5 and c = -3
The discriminate is found using the formula b^2 - 4(ac)
Replace the letters with their values:
5^2 - 4(-2*-3)
25 - 4*6
25-24 = 1
When the discriminate is greater than or equal to 0, there are two real solutions.
The answer is c) 2
Let x = # of original members
Cost per person (originally) = 832/x
Cost per person after 6 more people = 832/(x+6)
Solve 832/x=832/(x+6) +6 (because the cost was reduced by 6
Solve for x.
x = 26 or -32 (but x is number of members, so it can't be negative)
# of original members is 26.
Original cost is 832/26 = $32 per person.

Step-by-step explanation:
This is not a question we need to at least know it’s equation.
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for A
A = 180° - (90 + 48)° = 180° - 138° = 42°
----------------------------------------------------------
tan48° = 
= 
Multiply both sides by a
a × tan48° = 18 ( divide both sides by tan48° )
a = 
≈ 16.2 ( to the nearest tenth )
-----------------------------------------------------------
sin48° = 
= 
Multiply both sides by c
c × sin48° = 18 ( divide both sides by sin48° )
c = 
≈ 24.2 ( to the nearest tenth )
