Answer:
25m + 3
Step-by-step explanation:
Break the bracket, you will get:
- -25m - (-3)
= + 25m + 3
= 25m + 3
Hope this helped :3
Answer:
Option C.
Step-by-step explanation:
From the given figure it is clear that
So,
Using Intersecting Secants Theorem, we get
Divide both sides by 4.
Since, x = 11; PR = 12; PT = 15, therefore the correct option is C.
From the expression, the price is directly proportional to the boxes with k being the constant. therefore he bought 4 boxes for 25.6 having the initial constant to be 6.4
if he bought 10 boxes having a constant of 6.4 it becomes y=6.4*10 which becomes 64.
Answer:
x = 3
y = 4
hey, I am not 100% sure of the certainty of my answers, I am using what I remember about that topic but I do not know if it is right or wrong, I hope I have helped you, I did what I could.
Step-by-step explanation:
-3x + 2y = 23
5x + 2y = -17
X solution:
(you cancel the y)
-3x = 23
5x = -17
(you combine all the values above with those below)
2x = 6
(solve the ecuation normaly)
x = 6/2 = 3
Y solution:
(you replace the x)
-3(3) + 2y = 23
5(3) + 2y = -17
-9 + 2y = 23
15 + 2y = -17
(you combine all the values above with those below)
6 + 4y = 6
(solve the ecuation normaly)
4y = 0
y = 4
(I do not really know if the answer here is 0 or 4 since when passing the 4 to divide it would be 0/4 and I do not understand very well how that is solved)
If 15 t-shirts were sold and 1/5 were grey,
then 4/5 of the shirts were white
Now, 4/5 of 15 = 12
∴ of the shirts sold, 12 were white
