Answer:
Originally there were 30, 25 cents stamps and 20, 15 cent stamps.
Step-by-step explanation:
We are given the following in the question;
Let x be the number of 25 cents stamps and y be the number of 15 cents stamps.
Marci has a total 50 stamps.
Thus, we can write
Also,
Total cost = $16.50
Thus, we can write the equation:
Solving the two equations:
Originally,
Thus, originally there were 30, 25 cents stamps and 20, 15 cent stamps.
Answer:
2 possible coordinate pairs
N (8, 17) OR (-12, -3)
Step-by-step explanation:
The rule:
(x, y) => (x + 10, y + 10) OR (x - 10, y -10)
(-2 + 10, 7 + 10) OR (-2 - 10, 7 -10)
(8, 17) OR (-12, -3)
Hope this helps!

Answer:
10.5 cm^2
Step-by-step explanation:
Area of a triangle = 1/2(L x H)
Reading from the diagram
length = 7 cm
height = 3 cm
therefore
Area of the triangle = 1/2( 7×3)
Area = 10.5 cm^2
Answer:
7x^2+2x-4
Step-by-step explanation:
a standard form is ax+by=c
5x^2 add 2x^2=7x^2 then -2x but when you have a -10 +6 you get -4 giving you the answer of 7x^2 +2x -4
