Answer:

A. x = 6

Step-by-step explanation:

a^2 + b^2 = c^2

8^2 + b^2 = 10^2

64 + b^2 = 100

b^2 = 100 - 64

b^2 = 36

√b^2 = √36

b = 6

Answer:

See below.

Step-by-step explanation:

13. D

Simply subtract. 85376 - 37793 = 47583.

14. C

[Something] - 32497 = 26348

Add 32497 to both sides:

[Something] - 32497 + 32497 = 26438 + 32497

[Something] = 58845

15. C

Compute each difference:

A: 51455 - 26478 = 24977

B: 49351 - 15274 = 34077

C: 63286 - 37439 = 25847

(D: 46307 - 21550 = 24757)

16. B

Simply subtract:

143864 - 112955 = 30909

17. A

First, find the difference:

85732 - 39864 = 45868

Only 45798 (A) is less than 45868.

(Note that B is equal to, not less than).

18. C

Subtract:

45932 - 29574 = 16358.

19. B

Subtract:

96834 - 31727 = 65107 - 12156 = 52951

20. C

27301 - 12352 - [Something] = 7356

14949 - [Something] = 7356

Add [Something] to each side:

14949 = 7356 + [Something]

Subtract 7356 from each side.

7593 = [Something]

Note: Do you need help with subtraction specifically? These questions can be solved with simply with a calculator, but perhaps that is not the intention here. Anyways, I recommend using Khan Academy to improve your arithmetic skills if necesary.

Given that for an arithmetic sequence, the first term is q and the second term is qz.

otez555 [7]

Answer:

$d = q(z-1)$

$S_n = \frac{nq}{2}(2 + (n-1)(z-1))$

$S_{10} = 5q(9z -7)$

Step-by-step explanation:

Given

$T_1 = q$

$T_2 = qz$

Solving (a1): The common difference (d)

d is calculated as

$d = T_2 - T_1$

This gives:

$d = qz - q$

Factorize:

$d = q(z-1)$

Solving (a2): Sum of n terms

This is calculated using:

$S_n = \frac{n}{2}(2*T_1 + (n-1)d)$

Substitute values for T1 and d

$S_n = \frac{n}{2}(2*q + (n-1)q(z-1))$

$S_n = \frac{n}{2}(2q + q(n-1)(z-1))$

Factorize:

$S_n = \frac{n}{2}(q(2 + (n-1)(z-1)))$

$S_n = \frac{nq}{2}(2 + (n-1)(z-1))$

Solving (b): Sum of first 10.

In this case, n = 10

So:

$S_n = \frac{nq}{2}(2 + (n-1)(z-1))$

becomes

$S_{10} = \frac{10 * q}{2}(2 + (10-1)(z-1))$

$S_{10} = 5 * q(2 + 9(z-1))$

$S_{10} = 5q(2 + 9(z-1))$

$S_{10} = 5q(2 + 9z-9)$

$S_{10} = 5q(2 -9+ 9z)$

$S_{10} = 5q(-7+ 9z)$

$S_{10} = 5q(9z -7)$

If –3x+12 = 9x, then 5x=____

Viktor [21]

Answer:

5x=5

Step-by-step explanation:

You add the -3x to the side with 9x

Then you get 12= 12x

Then simplify 1x=1 which means 5x=5
