a population of insects increases at a rate of 1.5% per day about how long will it take to double A)2.5 days b) 5.0 days c) 46.6
ANTONII [103]

We can use population formula

P(t)=P_0(1+r)^{t}

we are given

interest rate is 1.5% per day

so,

r=0.015

now, we can plug values

P(t)=P_0(1+0.015)^{t}

P(t)=P_0(1.015)^{t}

we are given

P(t)=2Po

we can plug it

2P_0=P_0(1.015)^{t}

we can solve for t

2=(1.015)^{t}

t=46.55

so,

number of days is 46.5..........Answer

Prove that if -5(x + 4) = 70, the x = -18. Write a justification for each step.
crimeas [40]

Step-by-step explanation:

Let's solve your equation step-by-step.

−5(x+4)=70

Step 1: Simplify both sides of the equation.

−5(x+4)=70

(−5)(x)+(−5)(4)=70(Distribute)

−5x+−20=70

−5x−20=70

Step 2: Add 20 to both sides.

−5x−20+20=70+20

−5x=90

Step 3: Divide both sides by -5.

−5x

−5

=

90

−5

x=−18

(450) + (28.75x) = 967.50<br> solve for x
Galina-37 [17]

Answer:

18

Step-by-step explanation:

Hello,

In order to solve for x, we need to isolate the variable on one side of the equation.

To do this, we subtract 450 from both sides of the equation, and this will give you:

28.75x = 517.5

As mentioned, we need to isolate x, so we divide both sides by 28.75. This will give the following.

x = 18

Hope this helps!
