12) -5k - 19 = 5 - 13k

-5k = 24 - 13k

8k = 24

k = 3


14) -15n + 16 = 86 - 29n

-15n = 70 - 29n

14n = 70

n = 5


16) 13 - 3p = -5(3 + 2p)

13 - 3p = -15 - 10p

-3p = -28 - 10p

7p = -28

p = -4


18) 14a - 93 = 49 - 57a

14a = 142 - 57a

71a = 142

a = 2


20) 8v = 2(4v + 2)

8v = 8v + 4

No solution


22) 2(-4h - 13) = 37 + 13h

-8h - 26 = 37 + 13h

-8h = 63 + 13h

-21h = 63

h = -3


24) 11n - 3 = 9 + 5n

6n = 12

n = 2


26) -9n - 12 = 8 - 4n

-5n - 12 = 8

-5n = 20

n = -4

crimeas [40]

Hello! Your answer is below... Remember : h = height and v = volume

Answer:

H = 15.35 cm

V = 690.75 m^

Step-by-step explanation:

(H= height, V = volume, ^= square, √ = square root )

1. divide 9/2

=4.5 cm

2. use the pythagorean theorem

H=√16^-4.5^

H=15.35

if your looking for volume

1. use the formula for volume of the pyramid which is:

1/3 x base area x height

or

base area x height /3

2. then you substitute

1/3 x (9)(15) x 15.35

or

(9)(15) x 15.35 /3

V= 690.75 m^

Hope it helped u if yes mark me BRAINLIEST!

Tysm!

74,443 the value of the digit 4 in the hundreds place is 10 time the value of the 4 in what place value?
Inessa [10]
ANSWER: 4 in the TENS place value.
EXPLANATION:
Okay so 74,443
It is asking if the digit 4 in the hundreds which is 400 is 10 times as large as what other 4 digit
Now the other 2 fours in this number are one in the thousands and one in the tens (4000 and 40)
If you multiply 4000 by 10 that is MUCH larger than 400
If you multiply 40 by 10 you would equal 400
Therefore the answer is the 4 in the TENS place value.
