We have JM=ML due to the relation between sides and angles
Set 3x+4 = 5x-16
=> x= 28/5
Substitute back to the equation ( either one would work be cause they are equal) : 3 ( 28/5) +4 = 20.8
We have JL = JM+ML
=> JL = 20.8+20.8 = 41.6
Well, one example would be how much space is in a cardboard box, to ship something to a friend or relative.
We know the three measurements:
L = Length, W = Width, and H = Height.
And the formula for a volume of a cube is:
V = L*W*H
So say that:
L = 6 , W = 10 Feet, and H = 3 Feet.
By using the formula above we get the equation: V = 6*10*3
And that equals: 180 Feet.
So the volume of the box, or the space you have to send something is 180 square feet.
Does this help?
The link I used for some of this info, which has other useful math models is: https://www.mathsisfun.com/algebra/mathematical-models.html
They is 9dime and 13 Nickels because 13 x5=65 and 9 x10=90 .So 0.65+ 0.90= 1.55.
Answer:
Equation 1: 14t + 61s = 150
Equation 2: 14t + 25s = 78
Use Elimination (x)
(-1) (14t + 25s) = (78) (-1)
-14t - 25s = -78
14t + 61s = 150
+ -14t - 25s = -78
--------------------------
36s = 72
s = 2
Salad costs $2
Then find t
14t + 61(2) = 150
14t + 122 = 150
14t = 28
t = 2
Sandwich costs $2
I did say the answer is $35. Because, you should use the highest factor or whatever operation the problem is using, to find the answer. Not sure if it's some two-step problem....
