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

/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

A vat with 700 gallons of beer contains 4% alcohol (by volume). Beer with 6% alcohol is pumped into the vat at a rate of 7 gal/m
dolphi86 [110]

Answer:

5.2%.

Step-by-step explanation:

After 1 hour (60 / 100) * 700 = 420 gallons of beer have been exchanged.

So we have 420 gallons of 6%  and 280 gallons of 4% after 1 hour.

So the strength at that time =  (420* 6) + 280*4) / 700

= 5.2%.

Write a linear equation to model the following situation: Frankie has $500 in her savings account at the beginning of the year.
Juli2301 [7.4K]
A linear equation can be represented by: 

y = mx + b 

Where m = slope, and b = y intercept. 

The slope is a rate of change, so our slope is $150. 
The y intercept is the point where the equation crosses the y axis, or the "initial amount" in this case $500. 

So our equation will be: 

y = 150x + 500.
