Answer:
x = 29
Step-by-step explanation:
Follow the directions: substitute 13 for y in the first equation.
x + 13 = 42
Subtract 13 from both sides of the equation.
x +13 -13 = 42 -13
x = 29
The answer is B. A term is a group of numbers and/or variables connected by multiplication. A and b are both variables and it is an expression because there is no equal sign.
Given that number of working shifts = 3
Let number of loads of laundry that you can wash in 1 shift = x
Then number of loads of laundry that you can wash in 3 shift = 3x
Numerical value of the number of loads of laundry that you can wash in 1 shift is not given so it's not possible to convert "3x" into integer.
But whatever be the value say 5 loads of laundry is washed in 1 shift then the answer is given by 3x= 3*5= 15
You could be 31 and 37 are prime numbers nothing you multiply with a whole number will you get these numbers
The second equation is the first equation multiplied by -3. Therefore, The solution to the system of equations is all real numbers.
