Mathematics
1 answer:
GREYUIT [131]3 years ago
8 0

Answer:

x=4

Step-by-step explanation:

start by squaring both sides:

(\sqrt{-8+3x} )^2=(2)^2

squaring a square root cancels it out:

-8+3x = 4

solve for x by first adding 8 to both sides:

3x=12

then divide both sides by 3:

x=4\\

So, I need to find the value of b but im very confused on how to! Can someone help me?
Angelina_Jolie [31]

b = 78°

The angles at a point sum to 360°

that is 45 + 237 + b = 360

282 + b = 360 ( subtract 282 from both sides )

b = 360 - 282 = 78°

3/4 is added to x, the result is 9/8 . What is the value of x? Enter your answer in the box as a fraction in simplest form. Plea
pentagon [3]
⓵ Write down your complete equation:

x + ¾ = 9/8

⓶ Solve the equation in order to find the value of “x”:

x + ¾ = 9/8
- ¾ - ¾

x = 9/8 - ¾

There a 3 simple steps to subtract fractions:

⒈ Make sure the bottom numbers (the denominators) are the same.

9/8 - ¾ → They don’t have the same denominator.

You need to multiply the top number and the bottom number of ¾ by 2 :

3 (x2) 6
—- = ——
4 (x2) 8

So now you are left with : 9/8 - 6/8

⒉ Subtract the top numbers (the numerators). Put the answer over the same denominator :

9 - 6 = 3 → ⅜

⒊ Simplify the fraction (if needed) :

⅜ → The fraction is already simplified.

⇨ Your answer is: x = ⅜

There you go! I really hope this helped, if there’s anything just let me know! ☻
