Fourteen less children’s meals were served than adult meals at a barbecue. Children plate were 1.50 each and adult plates were 2
Annette [7]

Answer:

134 children and 120 adult plates were served

Step-by-step explanation:

let the children mean be x

Let the adult meal be y

If fourteen less children’s meals were served than adult meals at a barbecue, then;

y = x - 14 .... 1

IF Children plate were 1.50 each and adult plates were 2.00 each with a total of 441 in amount then;

1.5x + 2y = 441 .... 2

Substitute 1 into 2;

1.5x + 2(x-14) = 441

1.5x+2x-28 = 441

3.5x = 441+28

3.5x = 469

x = 469/3.5

x = 134

Recall that y = x - 14

y = 134-14

y = 120

Hence 134 children and 120 adult plates were served

alisha [4.7K]

Step-by-step explanation:

{:}\leadsto\sf 59-(2c+3)=4 (c+7)+c

{:}\leadsto\sf 59-2c-3=4c+28+c

{:}\leadsto\sf 56-2c=5c+28

{:}\leadsto\sf 5c+28=56-2c

{:}\leadsto\sf 5c+2c=56-28

{:}\leadsto\sf 7c=28

{:}\leadsto\sf c={\dfrac {28}{7}}

C=(7,-4) and D= (-8,5) CD=?
prisoha [69]

Answer:

Step-by-step explanation:

x_{1}=7 \ ; y_{1} = -4\\\\x_{2} = -8 \ ; y_{2}=5\\\\CD = \sqrt{(-8-7)^{2}+(5-[-4])^{2}}\\\\=\sqrt{(-15)^{2}+(5+4)^{2}}\\\\=\sqrt{225+(9)^{2}}\\\\=\sqrt{225+81}\\\\=\sqrt{306}\\\\=\sqrt{3*3*2*17}\\\\=3\sqrt{34}

Distance = \sqrt{(x_{2}-x_{1})^{2}-(y_{2}-y_{1})^{2}}
