What is the value of x in the equation 4(2x + 10) = 0? (1 point)

Mathematics
1 answer:
miskamm [114]3 years ago
4 0

Answer:

x = -5

Explanation:

4(2x + 10) = 0

[ Simplify both sides of the equation ]

4(2x + 10) = 0

(4)(2x) + (4)(10) = 0 [Distribute]

8x + 40 = 0

[ Subtract 40 from both sides ]

8x + 40 − 40 = 0 − 40

8x = −40

[ Divide both sides by 8 ]

8x  / 8 = −40 / 8

x = -5

Ok so their are 36 people that didn't need gel for there hair. so when you multiply 36 x 5 (because each cut costs 5 bucks) you get an answer of 180. so hold on to that and since their are 16 people that asked for gel you would need to first multiply 5 and 10% which gives you 0.5 so when you multiply 5.5 (because when you multiplied the 10% with the 5 you should get .5) times 16 you should get an answer of 88. when you add 180 with 88 you get an answer of 268. Ur welcome couuld u mark this brainlist plzzzzz

a candy necklace is extended from the top of a 10-foot ice cream cone to the ground. The necklace makes a 55 degree angle of the
Finger [1]

Answer:

The length of the necklace is 12.20 foot

Step-by-step explanation:

Given as :

The height of the ice cream cone to the ground = h = 10 foot

The angle make by the necklace of the ice cream cone = 55°

Let The length of the necklace = L foot

<u>Now, from figure </u>

Height = BC = h foot

The length of the necklace = L = AC

So, Sin angle = \dfrac{\textrm perpendicular}{\textrm hypotenuse}

Or, Sin 55° = \dfrac{\textrm BC}{\textrm AC}

Or, 0.8191 = \dfrac{h}{L}

Or, 0.8191 = \dfrac{10 foot}{L}

Or, L = \dfrac{10 foot}{0.8191}

∴  L = 12.20 foot

So, The length of necklace = L = 12.20 foot

Hence The length of the necklace is 12.20 foot Answer
