Hi again

Evaluate if x = 4
First thing we need to do is replace x by 4
3(4) + 1/ 4
(12 + 1)/4
13/4
Thus, your answer is D

Find the value of x. Can someone please help me, i’ve been stuck for hours
atroni [7]

Answer: Hi!

The value of the variable is 11.

The angles will be equal, as the lines intersect and make an X. To find the value of the angle, we would first subtract 2 from 35 and then divide by 3 to fill in the expression.

35 - 2 = 33

33 ÷ 3 = 11

The value of x is 11.

Hope this helps!

For a given rabbit population, the relationship between the number of adult female rabbits, F, and the number of offspring, R, t
Sphinxa [80]

Considering the given function in the problem, it is found that:

a. 9.6 offspring survive to maturity when there are 12 female rabbits in the population.

b. At least 18 female rabbits are required for there to be 13 offspring.

<h3>What is the given function in this problem?</h3>

The function gives the relationship between the number of adult female rabbits F and the number of offspring R as follows:

R = 3 + \frac{350F}{F + 625}

When there are 12 female rabbits, we have that F = 12, hence:

R = 3 + \frac{350 \times 12}{12 + 625} = 9.6

9.6 offspring survive to maturity when there are 12 female rabbits in the population.

For at least 13 offspring, we have that the number of rabbits needed is given as follows:

R \geq 13

3 + \frac{350F}{F + 625} \geq 13

\frac{350F}{F + 625} \geq 10

350F \geq 10F + 6250

F \geq \frac{6250}{340}

F \geq 18

At least 18 female rabbits are required for there to be 13 offspring.

A certain drug is made from only 2 ingredients: compound A and compound B. There are 3 milliliters of compound A used for every
defon

Answer: im guessing you need the amount of compound b


Step-by-step explanation:

1 think out problem

compound A =222m     compound B=3 milliliters of compound A used for every 2 milliliters of compound B

write compound B as an equation which is:

a=3+2b

compound a equation is: a=222

to continue you have to make compound B equation equal b

a=3+2b

-2b  -2b

a-2b=3

-a      -a

-2b/-2=3/-2-a/-2

b= -3/2+a/2

i am working on the substitution method: so now you substitute variables

problems are: b=-3/2+a/2 and a=222

substute a for a: b=-3/2+222/2

b=109.5

a=222

<u>compound A=222</u>

<u>compound B=109.5</u>

<u>add both for final answer or whatever: 109.5+222= 331.5</u>

<em>sorry for the long complicated answer hope you understand. i tried my best it should be right. sorry if my answer is wrong. </em>
