Number 4 and 5 I don’t know how to do them

Answer:

Step-by-step explanation:

54 = 6*9

That means there are 3 threes and 1 two

54 = 2*3 * 3 * 3

There are a pair of 3s and a two and a 3 left over.

The two and the three remain under the root sigh.

One of the pair of threes comes out of the root sign.

The other one is thrown away.

sqrt(54) = 3*sqrt(6)

Answer: -2*3 sqrt6)

Answer: - 6 sqrt(6)

Answer:

[tex] \frac{4}{55} [/tex]

Step-by-step explanation:

[tex] \frac{2}{25} \div \frac{11}{10} [/tex]

[tex] \frac{2}{25} \times \frac{10}{11} [/tex]

[tex] \frac{2}{5} \times \frac{2}{11} = \frac{2 \times 2}{5 \times 11} [/tex]

[tex] \frac{4}{5 \times 11}[/tex]

[tex] = \frac{4}{55} [/tex]

The given information is,

→ (2/25) ÷ (11/10) = ?

Let's find the required solution,

→ (2/25) ÷ (11/10)

→ (2/25) × (10/11)

→ 20/275

→ 4/55 {simplest form}

Hence, 4/55 is the answer.

Answer:

Each game would be 44.84 per order, so 2 games would be 89.68 and so forth.

Step-by-step explanation:

Take 39.99 and add 4.85 and that gives you the total for 1 game per order.

Answer:

y int = -3

Step-by-step explanation:

we get the y int when x = 0. so 6(0)-4y=12 would get us y= -3

Answer:

The choose a.35

[tex]g( - 2) = - ( - 2) - 6 = 2 - 6 = - 4[/tex]

[tex]f(g( - 2)) = {( - 4)}^{2} - 4( - 4) + 3 \\ = 16 + 16 + 3 \\ = 35[/tex]

Answer:

x + 2 + 3x = 30

Step-by-step explanation:

Both lengths are unknown, but Ginny's car length is described in terms of Zach's car length, so we choose a variable for Zach's car length.

Let x = Zach's car length.

Zach's car length is x.

"Ginny's car is 2 more than 3 times the length of Zach's car."

Ginny's car length is 2 + 3x.

Add the lengths:

x + 2 + 3x

"The sum of the lengths of both cars is 30 inches."

x + 2 + 3x = 30

Answer: x + 2 + 3x = 30

Answer:

1/2*1 =1/2

Step-by-step explanation:

because they both give the same value

for example a*b=b*a

Answer:

[tex]multiplicative \: identity \\ a \times b = b \times a \\ it \: is \: 1 \: in \: general \\ \\ so \: here \frac{1}{2} \times 1 = \frac{1}{2} \\ thank \: you[/tex]

Step-by-step explanation:

just try, donot know it will be right or wrong...

Answer:

[tex]4 {a}^{3} + 5 {b}^{4} = 4( {2}^{3}) + 5( {5}^{4} ) \\ = 4(8) + 5(625) \\ = 32 + 3125 \\ = 3157[/tex]

Answer:

The square root of a negative number does not exist among the set of Real Numbers. ... The imaginary number "i" is the square root of negative one. An imaginary number possesses the unique property that when squared, the result is negative.

Answer:

x = 6, BC = 60

Step-by-step explanation:

6x + 2x + 1 = 81

8x + 1 = 81

8x (+ 1 - 1) = 81 - 1

8x = 80

8x/8 = 80/8

x = 10

6x

6(10) = 60

Answer:

Step-by-step explanation:

EGB and EHD are the same angles.

Answer:

m∠EHD = 57°

Step-by-step explanation:

∠EGB and ∠EHD are corresponding angles. Therefore, they are congruent.

Answer:

20

Open the parentheses 2 minuses equals one positive. So we now have -1+5

-1 +5 = 4. 3+2 =5, 4 * 5 = 20

Answer:

2 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Change the mixed numbers to improper fractions

([tex]\frac{9}{2}[/tex] - [tex]\frac{11}{3}[/tex] ) + [tex]\frac{5}{3}[/tex] ← the LCM of 2 and 3 is 6

= [tex]\frac{9(3)}{2(3)}[/tex] - [tex]\frac{11(2)}{3(2)}[/tex] + [tex]\frac{5(2)}{3(2)}[/tex]

= [tex]\frac{27}{6}[/tex] - [tex]\frac{22}{6}[/tex] + [tex]\frac{10}{6}[/tex]

= [tex]\frac{5}{6}[/tex] + [tex]\frac{10}{6}[/tex]

= [tex]\frac{15}{6}[/tex]

= [tex]\frac{5}{2}[/tex]

= 2 [tex]\frac{1}{2}[/tex]

Answer:

[tex]y = \frac{ - 3}{4} x + 7[/tex]

The goal is to multiply by a certain number (10, 100, 1000, etc.) so that when the original number is subtracted from the multiple, the repeating element cancels out. 10x = 2 is the result of multiplying by ten.

Hey there! Here's your answer!

D.) 85

Here's why:

The two angles are alternate interior angles, which are congruent because DE and XY are parallel lines.

Answer:

Ur question are not logic i think u made some mistakes

Answer:

7

Step-by-step explanation:

You've said that both triangle are equal.

This means, both are in proportion

Let the unknown side be x

4 : 5 : x = 36 : 45 : 63

Divide LHS by 9

4 : 5 : x = 4 : 5 : 7

Since you may see x and 7 are same. So, the missing side is 7.

Answer:

Step-by-step explanation:

[tex]\frac{AB}{PQ} = \frac{BC}{QR}[/tex]                      #1 Find same sides  

So, [tex]\frac{4}{36} =\frac{BC}{63}[/tex]                 #2 fill it in.

36BC= 252                 #3 Cross multiply.

[tex]\frac{36BC}{36}[/tex]= [tex]\frac{252}{36}[/tex]                      #4 Divide by 36

BC= 7                           #5 Here's your answer!

If you want to check, plug the sides in.

[tex]\frac{4}{36} =\frac{5}{45} =\frac{7}{36}[/tex]

[tex]\frac{1}{9} =\frac{1}{9} =\frac{1}{9}[/tex]

The siplified fractions should all equal the same number. If they do, the triangles are similar.

Hope this helps!
