Hello there!

Thanks for posting your question!

Answer: x=18 and 18=x. *The answer must have negative sign.*

Explanation:

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

a-c=b-c

First, subtract by 3 both sides of an equation.

2x+3-3=39-3

Then, simplify by equation.

2x=36

Next, divide by 2 both sides of an equation.

2x/2=36/2

Finally, simplify by equation and it just gives us the final answer.

36/2=18

18*2=36

2*18=36

36/18=2

x=18 and 18=x

Hope this helps!

Thanks!

Have a great day!

A snack food manufacturer uses 2,000 kg of peanuts to make two different snack products. Product A contains 30% peanuts by mass

GalinKa [24]

Answer: 1250 kg.

Step-by-step explanation:

Let x = mass of product A.

y=mass of product B

Then , According to the given statement , we have

$0.3x+0.7y=2000-------------(1)\\\\x=3y-----------(2)$

Put value of x from (2) in (1) ,we get

$0.3(3y)+0.7y=2000$

$0.9y+0.7y=2000$

$1.6y=2000$

$y=\dfrac{2000}{1.6}=\dfrac{20000}{16}=1250$

Put value of y in (2) ,we get x= 3(1250)=3750 =mass of product A

Therefore, the mass of product B =1250 kg.

alisha and hailey want to rent a limousine for prom.the limo costs 700 for the night 0.15 per mile if they have 750 set aside fo

amm1812

The easiest way to figure this out is by first subtracting 700 from 750 to make sure we don't get confused. Now that you have 50 dollars left what would be best to do would be divide the 50 (because you have 50 dollars left) by the amount per mile (.15). That should be 333.33333333. Rounded it would be 333 miles.
