1) 5(h + 9) = 55 Distribute _____ to everything in parentheses.

1 answer:

8 0

9 + h = 55/5
9 + h = 11
11 - 9 = h
2 = h

The opposite of addition is subtraction, Subtract 9 from both sides, The opposite of multiplication is division, divide both sides by 5 is the first step, and final answer is h = 2.

Unit rate for typing 34 words in a minute in a half

katrin [286]

Answer:

Rate is 1.1333 words per second 

Step-by-step explanation:

We understand rating as frequency or speed of doing something per time (seconds mainly)

${ \green{ \tt{rate = \frac{item \: quantity}{time} }}} \\$

Let's find rate in terms of seconds (words per second)

${ \rm{rate = \frac{34 \: words}{ (\frac{1}{2} \times 60) \: seconds} }} \\ \\ { \rm{rate = \frac{34}{30} }} \\ \\ { \rm{rate = 1.133 \: \: words \: per \: second}}$

Help me please with explanation

8_murik_8 [283]

Step-by-step explanation:

angle AOB = x+3

angle AOC = 2x + 11

angle BOC = 4x-7

angle AOC = angle AOB + angle BOC

=> 2x +11 = (x+3) + (4x-7)

2x +11 = 5x - 4

=> 3x = 15

x = 5

subst x = 5 in the given formulas

angle AOB = x +3 =8

angle AOC = 2x + 11 = 21

angle BOC = 4x - 7 = 13
