Answer:

Step-by-step explanation:

I'm going to assume that the problem is -23x -214 = 274

And in that case...

1. First isolate the x-value by adding 214 to both sides of the equation:

-23x = 488

2. Then, divide both sides by -23 to truly get x alone:

x = -\frac{488}{23} or -21.22

Answer:

 x = -18

Add the opposite of the constant on the left:

 -2/3x = 21/4 +27/4 = 48/4 = 12

Multiply the equation by the inverse of the coefficient of x:

 x = (-3/2)(12) = -18

The solution is x = -18.

Answer:

The graph in the attached figure

Step-by-step explanation:

we have a exponential function of the form

y=a(b^x)

where

y ---> is the population of bacteria

x ---> the number of hours

a is the initial value or y-intercept

b is the base of the exponential function

r is the rate of change

b=(1+r)

we have

a=700\ bacteria

r=5\%=5/100=0.05

so

b=1+0.05=1.05

substitute

y=700(1.05^x)

For x=20 hours

substitute in the equation and solve for y

y=700(1.05)^{20} =1,857\ bacteria

Jim and Gail invested a total of $3,600 in a stock, in a ratio of 5:7. The stock made $6,450 on top of the initial capital. If t
Ket [755]

"Since the ratio is 5:7 you can think in total there was 12 equal blocks of money invested. 5 of those blocks belonged to Jim and 7 of those blocks belonged to Gail. Since they invested $3,600 and then made $6,450 in total there is $10,050. Divide that total into 12 equal blocks of $837.50 and 5 of those blocks belong to Jim. So he will get $4,187.50"
