Question

Hi everyone I really really NEED YOUR HELP WITH BORING ALGEBRA!
could you pls answer these question as soon as possible?

Q.1.Six less than a number equals to two. What is the number?


Q.2.Write an algebraic expression for each of the following:
(a) 3 subtracted from a number y.
(b) 5 is added to three times a number x.


Q.3.Write an algebraic expression for the following expressions:
(a) The sum of a number x and 4 is doubled.
(b) One-fourth of a number x is added to one-third of the same number.


Q.4.Think of a number x. Multiply it by 3 and add 5 to the product and subtract y subsequently. Find the resulting number.


Q.5.If the side of an equilateral triangle is x, find its perimeter.


Q.6.If x = 3, find the value of the following:
(i) x + 5
(ii) 2x – 3
(iii) x – 7



Q.7.If x = 2, y = 3 and Z = 5, find the value of;
(a) 2x + y + z
(b) 4x -y + z
(c) x – y + z


Q.8.State which of the following are equations with a variable?
(a) 12 = x – 5
(b) 2x > 7
(c) x2 = 5
(d) 5 + 7 = 3 + 9
(e) 7 = (11 x 5) – (12 x 4)



Q.9.Think of a number, add 2 to it and then multiply the sum by 6, the result is 42.






Q.11.Fill in the blanks:
(a) 5 added to -5 = ……….
(b) If x = 3, then 3x – 5 = …….
(c) If x = 1 and y = 2, then 2x + 3y = ……….
(d) If 10x – 6 = 14, then x = ……….
(e) 4 less than a number x = …….

Answer 1

Answer:

6 minus a number= 2

= 6-2 = 3

3 - no. =y =3y

5+ 3 multiply x

the sum of no. is x and 4 is doubled

= x and 4 +x and 4 = x this answer may be incorrect

1/4+ x = 1/3

x multiply 3 +5 and sub y

if the side of equilatrral triangle is x in equilatrral triangle all sides are equal

=x+x+x=3x

3 +5=8

second sorry I can't solve

2-3+ 5=

koi confusion ho to bolna

I creates lot of confusion

Answer 2

Answer:

ᴀᴡᴡ..sᴜʀᴇ ᴍᴀᴛᴇ♡ ʜᴇʀᴇ ʏᴏᴜ ɢᴏ!

Step-by-step explanation:

ǫ.1) x-6=2

=x=2±6=8

=x=8

ǫ.2)Ⓐ︎= ʏ-3

Ⓑ︎=3x±5

ǫ.3)Ⓐ︎=2(x±4)

Ⓑ︎=1/4x±1/3

ǫ.4)x×3=3x

ɴᴏᴡ, 3x±5-ʏ ᴀɴs.

ǫ.5)x±x±x=3x

ǫ.6)i= 3±5= 8

ii=2x3-3= 6x-3

iii=3-7= -4

ǫ.7)Ⓐ︎=2×2±3±5= 12

Ⓑ︎=4×2-3±5= 8±2=10

Ⓒ︎=2-3±5= 2±2=4

ǫ.8)Ⓐ︎,Ⓒ︎

ǫ.9)ʟᴇᴛ ᴛʜᴇ ɴᴜᴍʙᴇʀ ʙᴇ x.

ᴀᴛǫ, (ᴀᴄᴄᴏʀᴅɪɴɢ ᴛᴏ ᴛʜᴇ ǫᴜᴇs)

=(x±2)×6=42

=6x±12=42

=6x=42-12

=6x=30

=x=30/6=5

ǫ.11)Ⓐ︎=5±(-5)=0

Ⓑ︎=3x-5=9-5=4

Ⓒ︎=2x±3ʏ=2±6=8

Ⓓ︎=10x-6=14

=10x=14±6

=10x=20

=x=2

Ⓔ︎=x-4
