help me answer the last question

Answer:

No she is wrong.

Step-by-step explanation:

Let's simplify step-by-step.

6−3y+4+2y

=6+−3y+4+2y

Combine Like Terms:

=6+−3y+4+2y

=(−3y+2y)+(6+4)

=−y+10

Answer:

=−y+10

Answer:

D

Step-by-step explanation:

Start with the values inside parentheses.

6 + 4 = 10

10 / 2 = 5

Then subtract 1*3.

5 - 3 = 2

*B is incorrect because according to order of operations, 4/2 should be calculated before adding 6.

Answer:

x = -22

Step-by-step explanation:

Subtract 5 from both sides

3x + 5 (-5) = 2x - 17 (-5)  

3x = 2x - 17

Subtract 2x from both sides

3x (-2x) = 2x (-2) -22  

x = -22

Answer:

8

Step-by-step explanation:

Step 1: Add the cost of the posters together

Shark: 1 = $2

Jellyfish: 1 = $6

2 + 6 = 8

Step 2: Divide the result by the total amount Mr. Benson spent

64 ÷ 8

[tex]= \frac{64}{8}[/tex]

[tex]= 8[/tex]

Therefore, Mr. Benson bought 8 of each type of poster.

Answer:

the first one

Step-by-step explanation:

f(x) = |x+5| -1

Answer:

x = 9cm

using sine rule

a/sine(A) = b/sine(B)

a= x; A= 64° ( alternating angles)

b= 10 cm ; B = 90°

x/sine(64) = 10/sine(90)

x= {10 × sin(64)}/ sin 90

x = 9cm

Step-by-step explanation:

Answer:

Step-by-step explanation:

we know two sides of a triangle, one side is 7 feet, the other is 12 feet , so use Pythagoras theorem

[tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]

[tex]C^{2}[/tex] = [tex]7^{2}[/tex] + [tex]12^{2}[/tex]

[tex]C^{2}[/tex] = 49 + 144

[tex]C^{2}[/tex] = 193

C = [tex]\sqrt{193}[/tex]

C = 13.89 feet

Answer:

The square of the hypotenuse equals the square of the sum of the other two sides.

13.89ft

Step-by-step explanation:

The Pythagorean theorem states that the total of the squares on a right triangle's legs equals the square on the hypotenuse (the side opposite the right angle)—or, in popular algebraic form, a2 + b2 = c2.

Height of the Tent Pole = 7ft.

Base of the Pole of the Tent = 12ft.

Now we will use Pythagoras theorem to find how long the rope is.

Use of Pythagoras theorem

Hence, the length of the rope is 13.89ft.

Answer:

15.7%

Step-by-step explanation:

Experimental probability is the probability of something that is determined by doing an experiment.

To find the probability, divide the number of rolling a one and add all the occurrences of every other result.

So,

42 / (42 + 44 + 45 + 44 + 47 + 46) =

42 / 268 =

0.156716 =

15.6716

Rounded to the nearest tenth, the probability of rolling a one would be 15.7%.

Answer:

[tex]A=448[/tex]

Step-by-step explanation:

To find the volume of the given figure, one must multiply the lengths of all sides together. Therefore, set up an equation and solve,

[tex]V = (l)(w)(h)[/tex]

(V) indicates volume, (l) indicates the length of the base, and (h) indicates the height of the figure.

Substitute,

[tex]V=(8)(14)(4)[/tex]

Solve,

Answer:

120 combinations of CDs are possible

Step-by-step explanation:

The total combinations could be

[tex]10C_3[/tex]

[tex]\frac{10*9*8*7!}{7!*3!}[/tex]

On further expanding, we get -

[tex]\frac{10*9*8}{3!} \\\frac{10*9*8}{3*2*1} \\= 10*3*4\\= 120[/tex]

Hence, 120 combinations of CDs are possible

Answer:

36.3

Step-by-step explanation:

I tried using the Pythagorean Theorem to measure the length (tallness) of the TV.

[tex]a^2 + b^2 = c^2[/tex]

[tex]a^2 + (40)^2 = (54)^2[/tex]

[tex]a^2 + 1600 = 2916[/tex]

[tex]a^2 = 2916-1600 = 1316[/tex]

[tex]a = \sqrt{1316}[/tex]

[tex]a = 36.27671429[/tex]

When this is rounded up to the nearest tenth, it would go up to 36.3.

So, the length (tallness) of the TV would be 36.3 inches.
