The sum of two consecutive odd numbers is 284. Find each number please.
Vlad [161]
We can solve this by finding one of the numbers first
Let the smaller number be y. 
Since these 2 numbers are consecutive odd numbers, the larger number should be 2 more than the smaller one (y+2).

Therefore, 
y + (y+2) = 284
2y +2 = 284
shift +2 to the other side and turn it into -2
2y = 284 - 2
2y = 282
shift x2 to the other side and turn it into /2
y = 282/2
y = 141

Now we got the smaller number, which is 141, we can also find the larger number by adding 2 to it. 141+2 = 143, 
Therefore, your answer is 141 and 143

. Harold works at a men's clothing store, which marks up its retail clothing by 27%. The store purchases pants for $74.00, suit
Paraphin [41]

Answer:

567.69

Step-by-step explanation:

Let p represent the original price

The Mark up is 27%

= 27/100

= 0.27

= p + 0.27p

= 1.27p

The retail price for pants is

= 1.27(74)

= 93.98

The retail price for suit jacket is

= 1.27(325)

= 412.75

The retail price for dress shirt is

= 1.27(48)

= 60.96

Therefore the markup for a pair of pants, dress shirts and suit jacket can be calculated as follows

= 93.98 + 412.75 + 60.96

= 567.69

Find the exact value of x
tresset_1 [31]

ΔABC and ΔCBD are similar. Therefore we have the proportion:

\dfrac{AB}{BC}=\dfrac{BC}{BD}\\\\AB=6;\ BC=x;\ BD=2

Substitute:

\dfrac{6}{x}=\dfrac{x}{2}    <em>cross multiply</em>

(x)(x)=(6)(2)\\\\x^2=12\to x=\sqrt{12}\\\\x=\sqrt{4\cdot3}\\\\x=\sqrt4\cdot\sqrt3\\\\\boxed{x=2\sqrt3}

An emu that measures 22 inches in height is 14 inches less than 2 times the height of a stuffed toy canary. What is the height o
OlgaM077 [116]

Answer:  The height of the stuffed toy canary is 18 inches so Jesus is right.

Step-by-step explanation:

We can represent the first statement by the equation  22= 2x - 14    where x is the height of the stuffed toy canary  so solve for x

22 = 2x -14   Add 14 to both sides

+14          +14

36 = 2x       Divide both sides by 2

x = 18  

Jesus is right.
