<span>The sum of 5 times a number and -2, added to nine times a number.
.
Looking at the first part:
The sum of '5 times a number' and '-2'
we get
5x + (-2)
or
5x - 2
.
The above is then "added to nine times a number" to get:
5x - 2 + 9x
Combining x's we get:
14x - 2

<span>Take it piece by piece:
5 times a number, rewrite as 5x
plus -2, nothing to rewrite there, that's already simplified,
added to nine times a number, rewrite as 9x.
Now, rewrite as an equation:
5x-2+9x = (See, it already looks better!)
Now combine like terms:
5x + 9x -2= 14x - 2</span></span>
Answer:
the answer is B, complementary angles
Step-by-step explanation:
complementary angles are two angles that add up to 180 degrees
105 + 75 = 180
Responder:
15 m e 75 m
Explicação passo a passo:
Deixar :
Largura = x
Comprimento = 5x
Perímetro = 180
Já o terreno tem uma forma retangular; usamos a relação;
Perímetro = 2 (comprimento + largura)
180 = 2 (5x + x)
180 = 2 (6x)
180 = 12x
180/12 = x
15 = x
Largura = x = 15 metros
Comprimento = 5x = 15 * 5 = 75 metros
Medida de largura e comprimento, respectivamente:
15 m e 75 m

$103.75
Step-by-step explanation:
we know that
Karen earns $62.25 for working 9 hour
so
using proportion
Find out how much she will earn for working 15 hours

Answer:
90minutes
Step-by-step explanation:
Let the time taken for passengers to be checked-in be t
Let the number of staff working be w;.
If the time taken for passengers to be checked-in for a flight is inversely proportional to the number of staff working then;
t = kw
when t = 30, w = 5
30 = 5k
k = 30/5
k = 6
to get t when w = 15
t = kw
t = 6(15)
t = 90minutes
Hence it will take 90minutes long
