Answer:

(5c-d)/a = b

Step-by-step explanation:

First you would bring the d to the right side of the equation

ab=5c -d

Then, you will divide the right side of the equation by a to find the value of b

(5c-d)/a =b

Answer: b = 2a

Step-by-step explanation:

<u>Original equation</u>

a = (1/2) b

<u>Multiply 2 on both sides</u>

a * 2 = (1/2) b * 2

$\Large\boxed{b=2a}$

Can anyone help me I don’t understand plz

There we have an information of two functions $g(t)\, and \, h(t)$

Using this two functions $g(t)\, and \, h(t)$ , we need to find the composition of functions (h\circ g)(t).

The composition of two functions h and g is the new function , by performing g first and then performing h.

$(h\circ g)(t)=h(g(t))$

$g(t)=3(t+1)$

$h(t)=2t$

Composition of h and g (t) = $(h\circ g)(t)$

$=h(g(t))$

First plugin the value of $g(t)=3(t+1)$

$h(g(t))=h(3(t+1))$

$=h(3t+3)$

We know that $h(t)=2t$ , we need to find h(3t+3),

That is, to replace t by 3t+3,

$=2(3t+3)$

Now distribute 2 into 3t+3,

$=6t+6$

Now plug in $t=-6,$

$h(g(-6))=6(-6)+6$

$=-36+6 \\ =-30$

Thus the solution is (D). $h(g(-6))=-30.$

What's the prime factor of 92 ?

mariarad [96]

Prime factors are multiplying numbers that cannot be divided into smaller numbers.
Let's break down 92.
Divide 92 by 2.
2 x 46.
We can still break this down.
Divide 46 by 2.
2 x 2 x 23.
This is your prime factorization of 92.
I hope this helps!

Harlamova29_29 [7]

Answer:

Approximately 62 gallons of water will be used by Lee County by the year 2025.

Step-by-step explanation:

The amount, in millions gallons of water, spent by Lee County, in t years after 2019, is given by the following equation:

$P(t) = P(0)(1 + r)^{t}$

In which P(0) is the amount spent on 2019 and r is the increse rate, as a decimal.

In the year 2019, Lee County used approximately 55 million gallons of water.

This means that $P(0) = 55$

Historical trends show that each year the water demand is increasing by a rate of approximately 2.1%.

This means that $r = 0.021$

$P(t) = P(0)(1 + r)^{t}$

$P(t) = 55(1 + 0.021)^{t}$

$P(t) = 55(1.021)^{t}$

Approximately how many million gallons of water will be used by Lee County by the year 2025?

2025 is 2025 - 2019 = 6 years after 2019. So this is P(6).

$P(t) = 55(1.021)^{t}$

$P(6) = 55(1.021)^{6}$

$P(6) = 62.3$

Rounded to the nearest millions

Approximately 62 gallons of water will be used by Lee County by the year 2025.
