Answer:
The coordinates of B are ( 6,-3)
Step-by-step explanation:
A ( 8,3) B( x,y) M = (7,0)
To find the x coordinate of the midpoint add the two x coordinates of the endpoint and divide by 2
(8+x)/2 = 7
Multiply each side by 2
(8+x) = 14
Subtract 8 from each side
8+x-8 = 14-8
x = 6
To find the y coordinate of the midpoint add the two y coordinates of the endpoint and divide by 2
(3+y)/2 = 0
Multiply each side by 2
(3+y) = 0
Subtract 3 from each side
3+y-3=0-3
y = -3
The coordinates of B are ( 6,-3)
Answer:
94
Step-by-step explanation:
So
376= x + 3x
Where x is the hambugers and 3 x is cheeseburgers
so it is the same as
376= 4x
divide both sides by 4
x= 94
we can check by tripling x = 283 and adding the hamburgers we found to be 94 which gives us 376
C. 3/2 divided by 3
Alina has 3/2 hours to complete her homework. She should divide her 3/2 hours by the 3 assignments to determine how much time she will spend on each assignment. This turns out to be 1/2 hours, or 30 minutes, on each assignment. 3/2 hours is the same thing as 90 minutes, so this answer makes sense. We want the time to be divided by the number of assignments, not vice versa.
Answer:
Price of skateboard=
Step-by-step explanation:
Given: The price of a skateboard is 5 dollars less than 3 times the price of a pair of knee pads.
Lets assume the price of the knee pads be "k".
As given, The price of a skateboard is 5 dollars less than 3 times the price of a pair of knee pads.
∴ y-intercept is 5 and slope will be 3.
using y intercept expression to form an expression.
we know,
∴ Price of skateboard= 3\times k-5
Price of skateboard=
Hence, expression for price of skateboard is
Y=20+35x because the 20 is a 1 time thing and 35x because 35 is charged each month
