Answer: x < 30
Step-by-step explanation:
Let the cost of a jean be x
cost of a shirt = $25
cost of 3 jeans = 3x
since he wants to spend less than $115 , this means that
3x + 25 < 115
3x < 115 - 25
3x < 90
x < 30
Answer:
See below.
Step-by-step explanation:
First, it's obviously a line so the equation is a linear equation.
In order to find a linear equation, we first need the slope and the y-intercept. Recall the slope-intercept form:
, where m is the slope and b is the y-intercept.
We already know the point (0,3) which is the y-intercept. Thus, b=3.
To find the slope, use the slope formula:

Thus, the equation is:

Answer:
85
Step-by-step explanation:
by dividing 2550 from 30
(m-1)²
= m² - 2×m×1 + 1²
= <u>m² - 2m + 1</u>
Use the identity - (a - b)² = a² - 2ab + b²
Hope it helps cha :)
