(1) r+y<=15
<span>r>=5 </span>
<span>8r+12y>=120 </span>
<span>(3) assuming she will work 15 hours, y = 15-r </span>
<span>so </span>
<span>8r + 12(15-r) >= 120 </span>
<span>8r+180-12r>=120 </span>
<span>-4r+180>=120 </span>
<span>-4r >= -60 </span>
<span>r <= 15 </span>
<span>looks like she could work all 15 hours and still make 120 dollars </span>
<span>(4) r= 5 required hours in the restaurant then </span>
<span>8r + 12(15-r)= 160</span>

A área de um retângulo é igual a 44, sabendo que as suas medidas são iguais a 4 e (3x+2), calcule a medida do lado maior deste r

jekas [21]

Responda:

Explicação passo a passo:

Área do retângulo = comprimento * largura

Dado

Comprimento = 4

Largura = 3x + 2

Área = 44

Substitua na fórmula e obtenha x

44 = 4 (3x + 2)

44 = 12x + 8

12x = 44-8

12x = 36

x = 36/12

x = 3

Obtenha os lados mais longos

Lado mais longo = 3x + 2

Substitua x = 3

Lado mais comprido = 3 (3) + 2

Lado mais comprido = 11

Portanto, a medida do lado mais longo deste retângulo é 11

The top 3 already given.

<u>Solving the rest:</u>

Added 1 to both sides ⇒ (1) Addition property of equality

If a = b and b = c, ten a = c ⇒ ( 9 ) Transitive property

The w is substituted with 1 ⇒ ( 6 ) Substitution property

Both sides multiplied by 2 ⇒ ( 3 ) Multiplication property

Both sides divided by 2 ⇒ ( 4 ) Division property

Parenthesis opened ⇒ ( 5 ) Distributive property
