Answer:

A) Commutative

Step-by-step explanation:

The Associative has to do with re-grouping numbers. There are only two numbers so this does not apply here. Commutative is where you change the order; that's what the equation is demonstrating.

Mary and Jane have $48 to share in the ratio 3:5. How much did each girl 2 points

zubka84 [21]

Answer:

Mary- $18

Jane- $30

Step-by-step explanation:

Add the numbers in the ratio together to get 8, and multiply 8 by the variable of x. Divide the total amount of money that both girls earned by 8. You will get x=6. Multiply 6 by 3 to get the amount of money Mary earned, which is 18, and multiply 6 by 5 to get the amount of money Jane earned, which is 30.

x(3+5) = $48

3x + 5x = $48

8x = $48

8x/8 = $48/8

x = $6

3($6):5($6) = $18:$30

What is the value of x that makes the given equation true? 2(x−8)=x+5x

bixtya [17]

Simplify the right hand side:

$2(x-8)=6x$

Expand the left hand side:

$2x-16=6x$

Subtract 2x from both sides:

$-16=4x$

Divide both sides by 4:

$x=-4$

A) exponential is the right answer.

Step-by-step explanation:

The formula used for increase after same number of time is:

$A_t = A_0(1+r)^t\\Here\\A_0\ is\ the\ initial amount\\r\ is\ the\ rate\\and\\t\ is\ time$

We are given

A_0 = 35000

r = 3%

$A_t = 35000(1+0.03)^t\\A_t = 35000(1.03)^t$

The function is an exponential function is the value of t can be put equal to 1,2,3,4..... which will increase the final output exponentially

Hence,

A) exponential is the right answer.

There are five boys to every nine girls in an introductory engineering course .if there are 364 students enrolled in the course

Nadusha1986 [10]

Answer:

234

Step-by-step explanation:

So what we know is that

5x+9x= students

This equation is saying that for every 5 boys there are 9 girls

we can then plug in 364 for the number of students and add like terms

This means that 14x=364

this means that x=26

This means that there are 26 sets of 5 boys and 9 girls

this means that there are

130 boys

234 girls

P(x) = 3x + 4<br>q(x) = 2x2<br>Find q(P(x))

max2010maxim [7]

Answer:

Step-by-step explanation:

If we are to find q(p(x)), we are to start at the innermost part of the problem which is p(x). Take the function p(x) and fill it into q(x) every place you see an x:

$2(3x+4)^2$ is the composition of p into q. Now all we have left to do is simplify.

$(3x+4)^2=9x^2+24x+16$

Then we have to finally multiply in the 2 to get:

$18x^2+48x+32$
