<span>If the area of the rectangle shown is 150 square feet, we can use the equation 2x2 - 5x = 150 to find its dimensions.</span>
Each home room had 279 cans
5,022 divided by 18 = 279
279 times 18 = 5,022 . answer: 279 cans per homeroom
First setup the system of equations for the given case.
Let sandwich=x
and delivery fee =y
Equations are:
4x+y=33 Equation 1
8x+y=61 Equation 2
Subtract equation 1 from 2.
4x=28
x=7
Now substitute value of x in equation 1.
4(7)+y=33
28+y=33
y=5
So cost of single sandwich=$7 and Delivery fee=$5
Now cost of 12 sandwiches:
12x+y=85
Put y=5
12x+5=85
12x=80
x=6.67 which is less than 7. So, They are not able to get 12 sandwiches for $85.
Answer:
<h3>3 : 2 : 4</h3>
<h2>CALCULATIONS</h2>
<h3>Let;</h3>
<h3>Kofi's age = 9</h3>
<h3>kwaku's age = 2/3 *9 = 6 </h3>
<h3>Yaw's age = 2(6) = 12</h3>
<h3>ratio of ages = 9 : 6 : 12</h3>
<h3>Simplest form = 3 : 2 : 4</h3>
