The total weight of cabbage is 14 1/4
<h3 /><h3>What is Equation?</h3>
An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
Given:
Yasmin purchased 6 heads of cabbage that each weighed 2 and 3/8 pounds.
So,
2 and 3/8 = 19/8
1 cabbage = 19/8 pounds
6 cabbages = x pounds
1 * x = 6 * 19/8
x = 114/8
x = 14 2/8
x = 14 1/4

A two digit number has a tens digit and a ones digit.
Let's say x = tens digit and y = ones digit
"The sum of the digits is 5"
x + y = 5
The next phrase is "the number multiplied by 3 is 42" but we need to represent the number using the digits. So they need to be multiplied first by their place value and added together. [Example: 34 = 3(10) + 4(1)]
The number is: 10x + y
3(10x + y) = 42
The system of equations: (two equations for two unknowns)
x + y = 5
30x + 3y = 42
Then you can use substitution or elimination to combine and solve.
I'll use elimination, multiply the entire top equation by -3 and add the equations together. y will cancel out
-3x - 3y = -15
30x + 3y = 42
------------------
27x + 0 = 27
x = 1
then plug x = 1 into either equation to find y
1 + y = 5
y = 4
remember the x and y represent digits so the number xy is 14
Answer:
14
Step-by-step explanation:
mass of 100 centimeters of copper wire is 
so, mass of 1 centimeter of copper wire will be 
hence, 14 centimeters of copper wire will provide .28 copper
