Perimeter is adding all sides together. Two sides for the width and two sides for the length. 298-53-53 = 192 That is what is left for the length but you need two equal sides so 192/2= 96 centimeters
length is 96 centemeters
Answer:
<em>X=</em><em>-</em><em>1</em><em>8</em><em>/</em><em>7</em>
Step-by-step explanation:
-6x+18+2x=-18x-18
-4x+18= -18x-18
-4x+18x=-18-18
14x=-36
x=-36/14
x=-18/7
Answer:
$2800
Step-by-step explanation:
let x represent the amount earned on the sale of a car
let y represent the amount earned on the sale of a truck
6x+3y=4800-eqn 1
8x+y=4600-eqn 2
Make y the subject of eqn 2
y=4600-8x
Plug y=4600-8x into eqn 1
6x+3(4600-8x)=4800
6x+13800-24x=4800
13800-4800=18x
18x=9000
x=9000/18=500
Now plug the value of x into eqn 2
8(500)+y=4600
4000+y=4600
y=600
So the amount earned on the sale of a car is $500 and $600 on the sale of a truck
Therefore,if 2cars and 3trucks are sold then
2($500)+3($600)
$1000+$1800
=$2800
