<h3>The inequality for d is: d < -3</h3>

<em><u>Solution:</u></em>

<em><u>Given inequality is:</u></em>

-7d + 8> 29

We have to solve the inequality

From given,

-7d + 8> 29

\mathrm{Subtract\:}8\mathrm{\:from\:both\:sides}\\\\-7d+8-8>29-8\\\\\mathrm{Simplify}\\\\-7d>21\\\\\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}

When we multiply or divide the both sides of inequality by negative number, we have to flip the inequality sign

\left(-7d\right)\left(-1\right)

Therefore,

-7d+8>29\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:d

What is the answer to this??
Helga [31]

Since the triangle is equilateral, all its angles are equal to 60°

AO is the bisector⇒∠OAD = 30°

AO AO is the hypotenuse, ∠OAD = 30°⇒

OD=10:2=5ft

By the Pythagorean theorem

10^2=AD^2+5^2\\AD=\sqrt{100-25} \\AD=\sqrt{75}

AC=AD+DC=2\sqrt{75}=10\sqrt{3}

S=\frac{a^2\sqrt{3} }{4}

S=\frac{(10\sqrt{3})^2\sqrt{3}  }{4} =\frac{300\sqrt{3} }{4} =75\sqrt{3} ft^2

Answer: A) S=75\sqrt{3}ft²

P.S. Hello from Russia and sorry for my bad english :^)

Use the three steps to solve the problem.
Oksana_A [137]

Answer:

If the second of the three numbers is  

n

, then the first and third are  

n-  1 and  n + 1 , so we find: 117 = ( n − 1 ) + n + ( n + 1 ) = 3n  

Dividing both ends by  

3  we find: n = 117/  3   = 39

So the three numbers are:

38 , 39 , 40

Step-by-step explanation : I hope it helps please don't forget to mark me brainliest  .  :)

Angles: can somebody tell me the angles of X, Y, Z please p.s 25 points if answered correctly
antoniya [11.8K]

Answer:

X=30; Z=80; Y=70

Step-by-step explanation:

The straight lines equal 180 and you subtract 180 to 150 and 180 to 100 to get 30 and 80 and the inside of a triangle is 180 and you subtract 30 and 80 to 180 to get 70.
