Answer:
S = 1.25
B = 3.50
Step-by-step explanation:
I assume you need to know how much a burger and how much a soda is.
Basically it's a system of equations.
5B + 9S = 28.75
10B + 10S = 47.5
There are a few ways to do this, if you like I can show another, but this is how I usually solve a normal system of equations.
First solve for one variable in one equation. I am going to choose to solve for B in 10B + 10S = 47.5
10B + 10S = 47.5 (divide the whole thing by 10)
B + S = 4.75 (subtract S from both sides)
B = 4.75 - S
Now plug this B into the other equation.
5B + 9S = 28.75
5(4.75 - S) + 9S = 28.75
23.75 - 5S + 9S = 28.75 (Now just solve for S
4S = 5
S = 5/4
S = 1.25
Now plug THIS back into the first one.
B = 4.75 - S
B = 4.75 - 1.25
B = 3.50

Answer:
h=55
Step-by-step explanation:
1. Determine that the two unknown interior angles of the triangle are congruent. This is true because they are both equal to (180-2h) degrees. You know this because straight lines at to 180 degrees, so (2h) degrees plus the unkown angle is 180 degrees.
2. Solve for triangle's interior angles. Triangles' angles add up to 180 degrees, and you are given that one angle is 40 degrees and you just determined that the other two angles are congruent. Set up the equation 180=40+2x, in which x=the degrees in each of the unkown angles.
2x+40=180, 2x=140, x=70. Each of the unknown interior angles is 70 degrees.
3. Use the straight angle theorem to solve for h. In step 1, we determined that the interior angles were each equal to 180-2h, so the equation was x=180-2h. You know know x, so plug it in and solve for h.
180-2h=70
-2h=-110
2h=110
h=55
Answer:
The explanation is given below:
Step-by-step explanation:
The computation is shown below:
If we add 7 and 2 then it provides 9 and then subtract 2 from 9 it provides 7 and then subtract 7 from 9 it provides 2 and like this way it follows for others two
7 + 2 = 9
9 - 2 = 7
9 - 7 = 2
8 - 3 = 5
5 + 3 = 8
8 - 5 = 3
3 + 7 = 10
10 - 7 = 3
10 - 3 = 7
