X=cost per hamburgurs
y=cost per hot dog
200x+150y=1450
200x+250y=1750
we can multiply first equation by -1 and add to 2nd
-200x-150y=-1450
<u>200x+250y=1750 +</u>
0x+100y=300
100y=300
divide both sides by 100
y=3
sub back
200x+150y=1450
200x+150(3)=1450
200x+450=1450
minus 450 both sides
200x=1000
divide both sides by 200
x=5
the cost of a hamburgur is $5
the cost of a hot dog is $3
Answer:
Ingrid collected 3 times as many Food boxes as she did cans of Food.
Step-by-step explanation:
Ingrid collected 6 cans of food from the food bank.
Ingrid collected 18 boxes of food from the food bank.
In order to determine the relationship
let cans of food = x = 6
So the boxes of food will be 3x = 3*6 = 18
So the relation between Cans of food and boxes of food will be
Ingrid collected 3 times as many boxes as she did cans
Answer:
Step-by-step explanation:
So you do 3.29*12.6=41.454. Since we are dealing with money we round to get $41.45
The value of x is 6 cm.
Step-by-step explanation:
Given,
Area of rectangle = 56 cm
Length of rectangle = x+2
Width of rectangle = 2x-5
Area = Length * Width
Factorizing
Either,
2x+11 = 0 => 2x=-11
Or,
x-6=0 => x=6
As x is added to dimension, it cannot be negative.
Therefore,
The value of x is 6 cm.
