Answer:

x= -16

Step-by-step explanation:

-3x-8/ 4 = 10

Here we can try to isolate x and so we have to first multiply 4 on each side.

-3x-8= 40

Then we can add the 8 to each side.

-3x= 48

Next, divide the -3 onto each side and we can get the answer!

x= -16

In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths. AB=4 and BC=3, Find AH, CH and BH.

IRISSAK [1]

Answer:

AH = 3.2
CH = 1.8
BH = 2.4

Step-by-step explanation:

It can be convenient to compute the length of the hypotenuse of this triangle (AC). The Pythagorean theorem tells you ...

AC^2 = AB^2 + CB^2

AC^2 = 4^2 + 3^2 = 16 + 9 = 25

AC = √25 = 5

The altitude divides ∆ABC into similar triangles ∆AHB and ∆BHC. The scale factor for ∆AHB is ...

scale factor ∆ABC to ∆AHB = AB/AC = 4/5 = 0.8

And the scale factor to ∆BHC is ...

scale factor ∆ABC to ∆BHC = BC/AC = 3/5 = 0.6

Then the side AH is 0.8·AB = 0.8·4 = 3.2

And the side CH is 0.6·BC = 0.6·3 = 1.8

These two side lengths should add to the length AC = 5, and they do.

The remaining side BH can be found from either scale factor:

BH = AB·0.6 = BC·0.8 = 4·0.6 = 3·0.8 = 2.4

_____

The sides of interest are ...

AH = 3.2

CH = 1.8

BH = 2.4

Barry is thinking of a number.

Virty [35]

Answer:

10 and 30

Step-by-step explanation:

Let's focus on the first 2 parts of the hints :

The number must be even and a factor of 30 :

Let's write out the factors of 30 :

1 , 2 , 3 , 5 , 6 , 10 , 15 , 30

Now let's pick out the even ones :

2 , 6 , 10 , 30

Now let's take out the multiples of 5 :

10 and 30

These are the answers

Hope this helped and have a good day

*URGENT* I NEED HELP WITH THIS QUICK

Georgia [21]

The function:
f ( x ) = x * 0.965^t
where x is the initial amount and t is the number of the years
80 = x * 0.965^3
80 = x * 0.89632
x = 80 : 0.89632 ≈ 89
Answer:
The initial amount of animals was 89.

Hope this helps!
Have a nice day :)
