Answer:

$y = 2 + \frac{1}{2}x$

Step-by-step explanation:

Given

Represent Carlos with y and his brother with x.

Analysing the statement one after the other:

Half of his brother's amount is: $\frac{1}{2}x$

$2 more: means we add 2 to $\frac{1}{2}x$

So, we have: $2 + \frac{1}{2}x$

The above represent Carlos's amount.

So, the expression is:

$y = 2 + \frac{1}{2}x$

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

Round each mixed number to the nearest whole number. Then, estimate the quotient.

Anni [7]

You would round up because 24 16/17 is closer to 25 and 4 8/9 is closer to 5.
which would be 25/5 which estimates to 5.
