Answer:
Step-by-step explanation:
Total weight of all of the filled jars with jam = 211.2 ounces
When empty, each jar weighs 1.2 ounces
Total weight of 2 dozens of empty jar = 24 × 1.2 ounces
= 28.8 ounces
Total weight of jam in 2 dozens jar = Total weight of all of the filled jars with jam - Total weight of 2 dozens of empty jar
= 211.2 ounces - 28.8 ounces
= 182.4 ounces
The weight of jam in one jar = 182.4 ounces / 24 jars
= 7.6 ounces
The weight of jam in one jar = 7.6 ounces
Answer:
Concept: Mathematical Computation
- In plain text it is: square root of 49
![\sqrt{49}](https://tex.z-dn.net/?f=%20%5Csqrt%7B49%7D%20)
- We need to values such that x × x = 49
- Hence
![\sqrt{49} = 7](https://tex.z-dn.net/?f=%20%5Csqrt%7B49%7D%20%20%3D%207)

So if you let x and y be the two numbers...
the sum of the two means you add them together... so you get:
x+y=56 : the difference means you subtract them.. so
x-y = 16
now you have two equations and two unknowns... which you can solve with a variety of methods... you can use elimination, substitution, or trial and error.
x+y=56
x-y = 16
I will use the elimination method: Because there is a plus y and a negative you cancel that out and you add the 2x's. Therefore:
2x=72
x=36
Now, you can plug in 36 into one of your original equation:
36+y=56
y=20
Those are your two numbers!
The answer would be x= 27
You would take the 30 from the angle and make an equation with the x+3
Steps are:
X+3=30
Subtract 3 from 30 to get you 27
Therefore x= 27
