Answer:
no solutions
Step-by-step explanation:
10x+2y=42
5x+y=20
Multiply the second equation by -2 to use elimination
-2(5x+y)=20*-2
-10x -2y = -40
Add this to the first equation
10x+2y=42
-10x -2y = -40
--------------------------
0 = 2
This is never true. This means there are no solutions
-3 is an integer and a rational number.
Natural numbers and while numbers refer to positive numbers, so -3 cannot be either of those.
Answer:
Pretty sure its 7.5 units²
Step-by-step explanation:

Doing area with triangles is kind of the same as rectangle, just do base × height. But then divide it by two.
For example: base=3, height=7. With rectangles it would be 21 units².
But with triangles it would be 3·7=21 divided by 2, it would be 10.5 units²
This scenario is all about creating equal groups of 4 candies. Because we know the total number of candies that were used, the 4 is a part and we are missing the other part(groups). We can think of it as how many groups of 4 will result in 76. This is shown in Choice A.
Answer:
m = 
Step-by-step explanation:
k = 3m - 7
k + 7 = 3m - 7 + 7
k + 7 = 3m
= m
(I'm not 100% sure fyi)
