Sorry I'm late, here are the equations, just solve for x! Treat the inequalities like an = sign and solve!!
Answer:
see explanation
Step-by-step explanation:
Expressing as equations
9x + 10y = 297 → (1) ← that is B
8x + 5y = 194 → (2) ← that is D
To solve the system of equations, multiply (2) by - 2
- 16x - 10y = - 388 → (3)
Add (1) and (3) term by term to eliminate the term in y
(9x - 16x) + (10y - 10y) = (297 - 388), that is
- 7x = - 91 ( divide both sides by - 7 )
x = 13
Substitute x = 13 into either of the 2 equations and solve for y
Using (1), then
(9 × 13) + 10y = 297
117 + 10y = 297 ( subtract 117 from both sides )
10y = 280 ( divide both sides by 10 )
y = 28
Cost of a small box of candy = $13
Cost of a large box of candy = $28

<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Jon spent 1 hour 17 minutes less than Camden
Camden spent 47 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Camaden spent
= 3 hours or (180 minutes) - 47 minutes
= 2 hours 13 minutes.
Now, Jon spent = 2 hrs 13 minutes - 1 hour 17 minutes
= 56 minutes

Answer:
The answer should be x = -7/8 but it doesn't say that for any of the choices
Step-by-step explanation:
The answer is 18/5 and simplify that and u get 3 3/5.
