We know that 2x + 5 = 10 - 3x, and because of this we can solve for x.

2x + 5 = 10 - 3x

+3x

5x + 5 = 10

-5

5x = 5

x = 1

We can plug x into each x value to verify if this is true.

2(1) + 5 = 10 - 3(1)

2 + 5 = 10 - 3

7 = 7

First, rewrite 9/10 and 11/12 so that they have a common denominator

Licemer1 [7]

Step-by-step explanation:

Find common denominators:

$\frac{9}{10} \times \frac{12}{12} = \frac{108}{120}$

$\frac{11}{12} \times \frac{10}{10} = \frac{110}{120}$

Now compare:

$\frac{108}{120} < \frac{110}{120}$

$so \: \frac{9}{10} < \frac{11}{12}$

Joe is the proud owner of Joe's Old Time BBQ Pit. He sells two types of BBQ sauce - Hot N' Spicy and Mild Mannered. Each gallon

oksano4ka [1.4K]

Answer:

P=$254

Step-by-step explanation:

let Hot N' Spicy be x

and Mild Mannered be y

the objective function is

38x+35y=P

the constraints are

1. tomato sauce

2x+3y=18--------1

2. hot peppers

2x+y=10--------2

solving 1 and 2 we have

using substitution method

2x+y=10--------2

y=10-2x

put y=10-2x in eqn 1

2x+3(10-2x)=18

2x+30-6x=18

2x-6x=18-30

-4x=-12

x=12/4

x=3

put x=3 in eqn 2 we have

2(3)+y=10

6+y=10

y=10-6

y=4

He should make 3 gallons of Hot N' Spicy

and 4 gallons Mild Mannered

38(3)+35(4)=P

114+140=P

254=P

P=$254
