find the value of A


help please

Answer:

remove the bracket 5x-1+5x collect like term 5x+5x-1

10x-1 is the answer

Answer:  A:  3x^2y^(3/2)

Step-by-step explanation:

This can be written as

(81*x^8*y^6)^(1/4)

Then multiply each exponent by (1/4):

81^(1/4)*x^(8(1/4))y^6(1/4))

81^(1/4) = 3

x^(8(1/4)) = x^2

y^6(1/4)) = y^(3/2)

The result:  3x^2y^(3/2)

Answer:

7

i know

Answer:

4/8 (2/4)

Step-by-step explanation:

1/4 is 2/8

He ate 2/8 pizza for dinner

Then he ate 1/4 (2/8) the next day

So he has 4/8 (2/4) pizza left

Answer:

12. C

13. A

Step-by-step explanation:

Answer:

- 1/4

Step-by-step explanation:

Where you see X, substitute with 1/3

Solve the power/exponent first:

6(1/3) = 2

That is ; - 4(1/4)^2

Solve the parenthesis:

(1/4)^2 = 1/16

-4(1/16)

= - 1/4

Answer:

10 is B

11 is D

Step-by-step explanation:

Answer:

a) 1

b) There is no limit to which the largest number can be because we are only given information about the median.

c) 1

d) 90

Answer: 120

Step-by-step explanation:

Answer:

120 1 062 = × P . giving P = ÷ 120 1 062 . = 106 799

Answer:

No factors.

3 - x^2 is prime.

The square root of pi is 1.77245385091.

Answer:

  49 in

Step-by-step explanation:

The circumference of a circle with radius r is ...

  C = 2πr

The disc with the given radius has a circumference of ...

  C = 2π(7.75 in) ≈ 49 in

Answer:

they are not similar

Step-by-step explanation:

MN/VW=16/22=8/11

LN/UW=20/28=5/7

LM/UV=25/35=5/7

there is no information about the angles, you apply SSS but in this situation not all sides are proportional

Answer: no

Step-by-step explanation:

first, we have to simplify when finding if they are equivalent or not.

1:4 = 0.25

12:3 = 4:1

Answer:

Yes (if your doing fractions)

Step-by-step explanation:

If you didn’t know how to simplify you could see the greatest possible multiple that 3 and 12 share. So 3 is the greatest possible multiple because 3x4=12. So you do the denominator and numerator to divide 3 and eventually you will get 1/4. (Sorry if I’m not accurate)

Answer:

The Greatest Common Factor of 24 and 9 is 3.

Answer:

3

Step-by-step explanation:

the biggest number u can divide 24 and 9 commonly is 3

the answer might be 18.64 but im actually kinda du.mb so its probably not right.

Answer:

is 10 points alot? the other guy don't think so

Answer:[tex]6\pi[/tex]

Step-by-step explanation:

240/360 can be simplified to 2/3. r^2 can be substituted for 9, and 2/3*9 is 6.

Answer:

C. -4 > -7

Step-by-step explanation:

answer= option C

Answer:

A = 192

Step-by-step explanation:

3 x 8^2

3 x 64 = 192

Answer:

Option A, B, and D are true.

Explanation:

A coefficient is the number that is being multiplied by a variable. For example, in 7b, 7 would be the coefficient.

Terms are the numbers used in the equation. For example, in 3 + 2, 3 and 2 would be the terms.

3n and 5m are not coefficients as there are variables included. 3n and 5m are examples of a variable.

A constant is a number that is not multiplied by a variable. For example, in 8x + 3 + 2b, 3 would be the constant.

Hope this helped :)

Steps to multiply using Long Multiplication

Multiplying 2-Digit by 2-Digit Numbers

Let us multiply 47 by 63 using the long multiplication method.

1. Write the two numbers one below the other as per the places of their digits. Write the bigger number on top and a multiplication sign on the left. Draw a line below the numbers. 



2. Multiply ones digit of the top number by the ones digit of the bottom number.

Write the product as shown.



3. Multiply the tens digit of the top number by the ones digit of the bottom number.



This is our first partial product which we got on multiplying the top number by the ones digit of the bottom number.

4. Write a 0 below the ones digit as shown. This is because we will now be multiplying the digits of the top number by the tens digit of the bottom number. Hence, we write a 0 in the ones place.



5. Multiply the ones digit of the top number by the tens digit of the bottom number.



6. Multiply the tens digit of the top number by the tens digit of the bottom number.



This is the second partial product obtained on multiplying the top number by the tens digit of the bottom number.

7. Add the two partial products.

 

In long multiplication method, the number on the top is called the multiplicand. The number by which it is multiplied, that is, the bottom number is called the multiplier.

So, a long division problem will have:



We follow the same method for multiplying numbers greater than 2-Digits.

The figure below shows the long division method to multiply 357 by 23

Answer:

- 1

Step-by-step explanation:

x + y ← substitute x = 2 and y = - 3 into the expression

2 + (- 3)

= 2 - 3

= - 1

Given expression:

Distribute this to get:

Correct choice is D

Answer:

D. 5 (2) + 5 (7)

Step-by-step explanation:

Given expression:

• 5(2 + 7)

Distribute this to get:

• a(b + c) = ab + ac

• 5(2 + 7) = 5(2) + 5(7)

correct choice is D
