<span>The answer is:  [C]:  
__________________________________________________________
Multiply each side by −8, subtract 35 from each side.

___________________________________________________________
Explanation:
___________________________
Given: You have (-1/8)*(x + 35) = -7
________________________________________
Note that all the answer choices given start with: "Multiply each side by...."; 
</span>____________________
Given the choices, multiplying EACH SIDE of the equation by "(-8)" would make sense, since doing would cancel the "(-1/8)" on the "right-hand side" of the equation above to a "1" (i.e "cancel out" that ("-1/8") value); and would result in making the "right side" of the equation above ("-7") a positive integer number. 
 Then you would be left with:  x + 35 = 56 ; so the next step would be to:
__________
Subtract: "(35)" from each side of the question [hence the answer choice] to isolate "x" on one side of the equation; and to solve for "x".

2t+5v=37 and 4t+3v=39 

Solve the first for t

t=18.5-2.5v and use this t in the second equation...

4(18.5-2.5v)+3v=39

74-10v+3v=39

-7v=-35

v=$5.00  and since t=18.5-2.5v

t=$6.00

So tuna sandwiches cost $6.00 and vegetarian sandwiches cost $5.00.

Help me please I have to finish this by tonight

Answer:

a=13 b=13

Step-by-step explanation:

Because the triangles are congruent, their corresponding angles will be congruent, too.

So, ∠Y≅∠S  and ∠Z≅∠T.

Set the values of these angles equal to each other and solve.

∠Y≅∠S               ∠Z≅∠T

4a-4= 48                5b-3= 62

4a=52                    5b= 65

a=13                        b= 13
