Answer 1

Given:

The expression is

[tex]9\sqrt{x}-3\sqrt{x}[/tex]

To find:

The result after subtracting the radicals.

Solution:

We have,

[tex]9\sqrt{x}-3\sqrt{x}[/tex]

We need to combine these terms.

Taking out common factors, we get

[tex]=(9-3)\sqrt{x}[/tex]

[tex]=6\sqrt{x}[/tex]

The result after subtracting the radicals is [tex]6\sqrt{x}[/tex].

Therefore, the correct option is B.

You can buy 3 T-shirts for $24. Write a proportion that gives the cost c of buying 7 T-shirts. $$

Answers

Answer:

3/24 = 7/x

c = $56

Step-by-step explanation:

A percent proportion is just basically a ratio, I could also write this as         3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.

a/b = c/d

Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.

Step-by-step explanation:

Shonda has $125. She spends 35% of the money she has on a concert ticket. How much did Shonda spend on the ticket?

Answers

Answer:

she spent $43.75

Step-by-step explanation:

you basically need 35% of $125

cool trick with this is "of" always means multiplication

35% x 125= 43.75

she spent $43.75

Shonda spent the amount of $43.75 on the concert ticket.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

To find out how much Shonda spent on the concert ticket, we can use the following proportion:

(35%) × 125 = x/1

where x is the amount of money spent on the concert ticket, and we know that 35/100 (or 0.35) is 35% of 125.

Convert percent into decimal form and solve for x:

(0.35) × 125 = x

Apply the multiplication operation, and we get

x = 43.475

Therefore, she spent $43.75 on the concert ticket.

Find the solution to the system. Write your solution as an ordered pair (x,y)
with no spaces, no solution, or infinitely many. 2x+6y=56 and 4x+12y=24 *

Answers

Answer:

No solution is your answer ( I do not know who you are supposed to type it out, but there are 0 solutions for this system).

Step-by-step explanation:

Key skills needed: Systems, Elimination, Recognizing Solutions

We are given:     2x + 6y = 56

                    and 4x + 12y = 24

To find x and y, we can use elimination. We can multiply the first one by -2 and both equations to eliminate x.

-2(2x+6y) = 56(-2) (Tip: Use distributive property

--> -2(2x)  = -4x

--> -2(6y) = -12y

--> 56(-2) = -112

This means that:    -4x - 12y = -112

Add this one to:   + 4x + 12y = 24

                              ----------------------

You will get -->       0 = -88

0 does not equal -88 so there is no solution for this!
