sertanlavr [38]

Answer:

Step-by-step explanation:

The nth term of arithmetic sequence is $a_n=a_1+d(n-1)$

So:

$a_{15}=a_1+d(15-1)\\\\53=-3+14d\\\\56=14d\\\\d=\dfrac{56}{14}=4$

UNO [17]

Alright, so I=prt. I is 1090-900=190=interest. It starts at 900, so that is p. R is 0.09. 1090=900*0.09*t, so 1090/(900*0.09)=t=around 13 years

What is value of x?

BlackZzzverrR [31]

(MAKE BRAINLIEST IF I HELPED)

Answer:

x=10

Step-by-step explanation::

We can use Triangle angle bisector theorem and proportions to solve this problem. We put the small triangle side over the large triangle side

8 x+4

------ = ------------

12 2x+1

Using cross products

8(2x+1) = 12(x+4)

16x+8 =12x+48

Subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

Subtract 8 from each side

4x+8-8 = 48-8

4x = 40

Divide by 4

4x/4 = 40/4

x = 10
