Answer:
Tim has 75 pencils and 25 pens
Step-by-step explanation:
To solve this create a system of equations. To do so, first create an equation for the total number of utensils that he has. Let x equal the number of pencils and y equal the number of pens.
x+ y = 100
Now make one for the comparison of the two and solve for the constant.
x = 3y
x - 3y = 0
Now to solve the system, multiply the second equation by -1 and add them together.
x + y = 100
-x + 3y = 100
-----------------
4y = 100
y = 25
Now that we have the number of pens, find the number of pencils using an equation.
x + y = 100
x + 25 = 100
x = 75
Answer: 9/7
Step-by-step explanation:
(7/9)^-1 means you have to find the reciprocal, which is 9/7
Answer:
The equation is 4y+8=9
The expression is 3-2
The inequality is 7/y < 6
Step-by-step explanation:
Answer:
7 is your answer
Step-by-step explanation:
Note the slope-intercept form:
y = slope(x) + y-intercept (or y = mx + b)
b is the y-intercept.
In this case, 7 is in the place of b, so 7 is your answer
