Answer:

B) 3\sqrt{3}

Step-by-step explanation:

First simplify the radical on the right.

\sqrt{75} is equal to \sqrt{25} *\sqrt{3} , because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.

Then we know \sqrt{25} is just equal to 25, which means the simplified version of \sqrt{75} is 5\sqrt{3}.

Then we can use this new representation to finish solving.

8\sqrt{3}-5\sqrt{3} =3\sqrt{3}, so the answer would be B

Let f(x)=-3x-7 Abe g(x)=4x-5 find (f•g)(-3)
LiRa [457]

Answer:

272

Step-by-step explanation:

note that (f • g)(x) = f(x) × g(x) = (3x - 7)(4x - 5)

To evaluate substitute x = 3 into (3x - 7)(4x - 5)

(f • g)(- 3) = (- 9 - 7)(- 12 - 5) = - 16 × - 17 = 172

Solve five and three sixths minus two and one third.
4vir4ik [10]

Answer:

Option 4: 3\frac{3}{18} is the correct answer.

Step-by-step explanation:

The given fractions are mixed fractions. the mixed fractions have to be converted into proper fractions before performing any operation like addition, subtraction etc.

Given fractions are:

5\frac{3}{6}-2\frac{1}{3}

Converting into proper fractions

=\frac{33}{6} - \frac{7}{3}

Making the denominator same

We have to multiply first fraction by 3 and second by 6

=\frac{33*3}{6*3} - \frac{7*6}{3*6}\\=\frac{99}{18}-\frac{42}{18}\\=\frac{99-42}{18}\\= \frac{57}{18}

Converting into mixed fraction: =3\frac{3}{18}

Hence,

Option 4: 3\frac{3}{18} is the correct answer.

nydimaria [60]

Answer:

1. $66

2. 30 + 4r

Step-by-step explanation:

Let

Price of admission into the park=$30

Price of every ride in the park=$4

Number of rides =x

Total cost of going to the park= 30+4x

1. How much money would Claire have to pay in total if she goes on 9 rides

Total cost of going to the park= 30+4x

When x=9

=30+4x

= 30 + 4(9)

=30 + 36

=$66

2. How much would she have to pay if she goes on r rides?

When x=r

Total cost of going to the park= 30+4x

= 30 + 4(r)

=30 + 4r
