Answer:
(1)
Karen:
Alice:
(2): Slope is 2
(3) y intercept
--- For Karen
--- For Alice
(4) They do not intersect
(5) No solution
(6) No
Step-by-step explanation:
Given
Solving (1): Complete the equation.
For Karen:
--- the rate
--- additional spendings
For Alice:
--- the rate
--- additional spendings
The general equation is;
For Karen, it becomes
For Alice, it is:
(2): The slopes.
In (1), we have:
--- the rate (for both Karen and Alice).
This rate implies the slope.
<em>Hence, the slope is 2</em>
(3): The y intercept.
The additional spendings in (1) means the y intercept.
So, we have:
--- For Karen
--- For Alice
(4) Because they have the same slope, they do not intersect
(5) Number of solutions.
Subtract both equations
This means there is no solution
(6) Can they spend the same amount on the same number of loaves
In (5), the equations have no solution
<em>Hence, it is not possible to spend the same amount for the same number of loaves</em>
Answer/Step-by-step explanation:
A term in an algebraic expression is a number standing on its own (constant), a letter (variable), or a number multiplying a variable (coefficient * variable).
Given the expression, 9a + 4b - 18, there are three terms in the expression, namely: 9a, 4b, and -18.
The student made an error in identifying the terms properly by excluding the variables, a and b, in the first term (9a) and in the second term (4b), respectively.
The correct terms are: 9a, 4b, and -18.
Answer:
x = -1255
Step-by-step explanation:
336+x/5=85
Subtract 336 from each side
336-336 +x/5=85-336
x/5 =-251
Multiply each side by 5
x/5 * 5 = -251 *5
x = -1255
Answer:
2.9 feet
Step-by-step explanation:
ten 2-foot paces
= 10 x 2
= 20 feet
Actual length
= 17.1 ft
Difference
= 20 - 17.1
= 2.9 feet
