Answer:
The individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony
Step-by-step explanation:
First we have to find 2 equations to express the problem
x = value of each item
y = total amount of money
3x = y
4 ( x - 2.25 ) = y
we replace the y by (3x) in the second equation and obtain the value of x
4 ( x - 2.25 ) = y
4 ( x - 2.25 ) = 3x
4x - 9 = 3x
4x - 3x = 9
x = 9
9 - 2.25 = 6.75
this means that the individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony
Between 30 and 48 okay hope you get it right but I’m not sure
Answer:
B
Step-by-step explanation:
Hey There!
they are asking for the equation in slope intercept form
Slope intercept form is y=mx+b
where m equals slope and b equals y intercept
to find the slope we do change in y over chang in x
as y goes up 2 x goes down 5 so the slope would be -2/5
the y intercept is at (0,4) so the y intercept is 4
now we add everything together and get that the equation in slope intercept form is
y=-2/5x+4
so we can conclude that the answer is B
The tools essential in performing geometric constructions is B
