Answer:

D:21

Step-by-step explanation:

Use the vertical angles equation.

4x + 13 = 5x - 8

Subtract 4x from 5x.

5x - 4x = x

13 = x - 8

Add 8 on both dies.

13 + 8 = 21

x = 21

JKLM has x that equals 21.

<JKLM and <LMJK equal 97 degrees.

Hope it helped!

Answer:

The answer is D:21

Step-by-step explanation:

make sure you use the right angles in the right order when solving for your answer...

4x+13=5x-8

5x-4x=x

13=x-8

add 8 on each side

x=21

X=7 and y=-2x+5 <br>help!
rusak2 [61]

If x = 7 you substitute all the x in the equation by 7:

y = -2(7) + 5
y = -14 + 5
y = -9


Hope it helped,

Please Help Me! It’s Math! Please!

Answer:

D. About 800 years

Step-by-step explanation:

Use the half-life equation:

A = A₀ (½)ⁿ

where A is the final amount,

A₀ is the initial amount,

and n is the number of half-lives.

0.90A₀ = A₀ (½)ⁿ

0.90 = (½)ⁿ

To solve for n, take log of both sides:

log 0.9 = n log 0.5

n = (log 0.9) / (log 0.5)

n = 0.152

It takes 0.152 half-lives.  The half-life of carbon-14 is 5730 years.

0.152 × 5730 years = 871 years

The closest answer is D.

Help pls And thanks
hoa [83]

Answer:

I think that 110 would be the correct answer. PLEASE correct if I'm wrong.

Step-by-step explanation:

See, a 90 degree angle is a right angle or like one of the ways you can split a square in half. l

So since that is a little more than a 90 degree angle, I would guess it would be 110.
