Answer:

x=1/9

Step-by-step explanation:

First, subtract the 3 over.

27x+3=6

27x=3

Then, divide by 27 on both sides.

x=3/27

3/27 can be simplified to 1/9

Find the given value of each angle for the following supplementary angles must add up to 180

juin [17]

QUESTION :

Find the given value of each angle for the following supplementary angles must add up to 180

$\Large{\underline{\mathcal{ Given : }}}$

one angle = (5x-13)°
another angle = (11x+65)°

$\Large{\underline{\mathcal{Tofind : }}}$

value of each angle

$\Large{\underline{\mathcal{Solution : }}}$

➱ᴛʜᴇ ᴛᴡᴏ ᴀɴɢʟᴇs ʟɪᴇs ᴏɴ ᴛʜᴇ sᴀᴍᴇ ʟɪɴᴇ

➱ѕσ ѕυм σƒ вσтн тнє αηgℓєѕ = 180°

therefore ,

⤳(5x-13)° + (11x+65)° = 180°

⤳5x -13° + 11x + 65° = 180°

⤳16x + 52° = 180°

⤳16x = 180° - 52°

⤳16x = 128°

⤳x = 128 /16

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\underline{\boxed{\sf{ x = \frak{\red{ 8 }}}}}$

hence ,

the two angles will be

⇛ᴏɴᴇ ᴀɴɢʟᴇ :

➛(5x-13)°

➛5(8) - 13

➛40 - 13

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\underline{\boxed{\sf{ᴏɴᴇ\: ᴀɴɢʟᴇ = \frak{\red{ 27° }}}}}$

⇛ᴀɴᴏᴛʜᴇʀ ᴀɴɢʟᴇ :

➛ (11x+65)°

➛11(8)+65

➛88 + 65

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\underline{\boxed{\sf{ᴀɴᴏᴛʜᴇʀ\: ᴀɴɢʟᴇ = \frak{\red{ 153° }}}}}$

Michael is saving to buy his senior ring. The base cost of the ring is $280 plus any upgrades he wants to purchase. If he saves

Leokris [45]

Answer:

Step-by-step explanation:

280/35=x

This is only for the base cost.

You can also right this as:

35(X)=280 and solve for x

35(X)=280

/35 /35

x=8

Hope this helps, good luck!

What value of x would make KM ∥ JN?

stepan [7]

Answer:

x = 10

Step-by-step explanation:

By the converse of the side-splitter theorem, if $\dfrac{JK}{KL}= \dfrac{NM}{ML}$ , then KM ∥ JN.

Substitute the expressions into the proportion:

$\dfrac{x-5}{x}= \dfrac{x-3}{x+4}$

Cross-multiply:

(x – 5)(x+4) = x(x – 3).

Distribute:

$x(x) + x(4) - 5(x) - 5(4) = x(x) + x(-3).$

Multiply and simplify:

$x^2 +4x- 5x - 20 = x^2-3x\\-x-20=-3x\\$Collect like terms$\\-x+3x=20\\2x=20\\$Divide both sides by 2\\x=10$

Solve for x: x = 10

Therefore, the value of x that would make KM parallel to JN is 10.
