The Downtown Community Barbecue served 280 dinners. A child’s plate cost $2.60 and an adult’s plate cost $9.50. A total of $1,79
Romashka-Z-Leto [24]

Answer:

the number of child plates and adults plates were served is 125 and 155 respectively

Step-by-step explanation:

Let us assume the child plate be x

And, the adult plates be y

Now according to the question

x + y = 280 .................(1)

2.60x + 9.50y = 1797.50 .............(2)

Now multiply by 2.60x in equation (1)

2.60x + 2.60y = 728

2.60x + 9.50y = 1797.50

-6.90y = -1069.50

y = 155

So, x = 280 - 155

= 125

hence, the number of child plates and adults plates were served is 125 and 155 respectively

Simplify the expression
Vaselesa [24]

To simplify this expression, you have to remember that when a number or a variable is raised to the negative exponent you have to reciprocate the number. In this expression, c^-8 will be reciprocated so it will become part of the numerator. Therefore, the final answer would be 12c^8/d^2.

A piece of sheet metal is 24 inches wide the cross section is 54 what is the depth
Leni [432]

Answer:

Width = 18, height = 3

Or

Width = 6, height = 9

Step-by-step explanation:

Complete question

( A piece of sheet metal 24 inches wide is bent to form a gutter as shown in the picture below, if the cross sectional area is 54 square inches, find the depth of the gutter).

X = width, Y = height

X - 2y = 24........ equation i

X = 24 - 2y.......... equation ii

Area = xy

54 = xy........ equation iii

Put equation ii into equation iii

54 = (24 - 2y) * y

54 = 24y - 2y²

2y² - 24y + 54 = 0........ equation iv

Solving equation iv using quadratic methods,

Factors = (y-3), (y-9)

(Y-3)(y-9) = 0

y = 3 or y = 9

Substitute y = 3 or y = 9 into equation ii

X = 24 -2(3) = 18 or x = 24 - 2(9) = 6

If Width = 18, height = 3

Or

Width = 6, height = 9
