Answer:

There would have been three people in the group.

Step-by-step explanation:

This is because if you add 2/3 together until you get that amount, it will add up to having three people. If this sounds confusing, here is a visual thing to help.

2/3+2/3=4/3 which can also equal 1 1/3

1 1/3 + 2/3 =2

you added 2/3 together three times to get two, so three is the answer.

Hope this helps!

If P(x) = x ^ 2 + x + 3 and Q(x) = 4x ^ 2 - 3 find P(8) .
lara [203]

Answer:

75

Step-by-step explanation:

Giving Q was not necessary because you aren't doing P(Q) or anything like that....

Anyways,

p(x) = x^2 + x +3\\

Since you're doing p(8), you would replace the x's with 8s.

(8)^2 + (8)  + 3 = 64 + 8 + 3 =75

So your final answer would be 75.

Mrs travis wants to have the clown deliver balloons to her secretary's office. Clowns R Fun charges $1.25 per balloon and $6 for
marysya [2.9K]

The <em>correct answer</em> is:


6 balloons.


Explanation:


Let x represent the number of balloons purchased.


We will call the function for Clowns R Fun c(x):

c(x) = 1.25x+6


We will call the function for Singing Balloons s(x):

s(x) = 1.95x+2


We want the amount for Clowns R Fun, c(x) to be less:

c(x) < s(x)

1.25x+6 < 1.95x+2


Subtract 1.25x from each side:

1.25x+6-1.25x < 1.95x+2-1.25x

6 < 0.7x+2


Subtract 2 from each side:

6-2 < 0.7x+2-2

4 < 0.7x


Divide each side by 0.7:

4/0.7 < 0.7x/0.7

5.7 < x

x > 5.7

The simplified form of the equation is \rm -69.19x+38.2.

<h2>Given that</h2>

Equation; \rm -9.2(8x - 4) + 0.7(2 + 6.3x)

<h3>We have to determine</h3>

The simplified form of the equation;

<h3>According to the question</h3>

To determine the simplified form of the equation following all the steps given below.

Equation; \rm -9.2(8x - 4) + 0.7(2 + 6.3x)

<h3>To simplify the equation multiple the terms and solve.</h3>

Then,

The simplified form of the equation is,

\rm =-9.2(8x - 4) + 0.7(2 + 6.3x)\\&#10;\\&#10;= (-9.2) (8x)- (-9.2)(4) + (0.7)(2) + (0.7) (6.3x)\\&#10;\\&#10;=-73.6x -(-36.8) +(1.4)+(4.41x)\\&#10;\\&#10;= -73.6x+36.8+1.4+4.41x\\&#10;\\&#10;=-69.19x+38.2

Hence, The simplified form of the equation is \rm -69.19x+38.2.
