Answer:
54
Step-by-step explanation:
Adam sells stationary cards in pack of 6
And also envelops in pack of 9
Therefore the minimum number of cards he have to buy can be calculated as follows
= 9×6
= 54
Answer:
r= 5
Step-by-step explanation:
Since the angles in triangle ACM indicate that it is a 30-60-90 triangle, we know that the other two sides of triangle ACM are 20 and 10 (30-60-90 triangles have a very specific side coefficient). This means that the sides of this triangle have side lengths 40, 10, and

. Adding these together you get 50+

Answer:
y = x - 3
Step-by-step explanation:
Basically, if the lines are parallel, they have the same slope, right? So that part is already complete
And to get the rest of the equation, plug in the points -2 and 1 into the equation for the x values. Then set the equation to solve for b
After you do that you should get b = -3
The slope is 1 and the y-int is -3
Thank me later ;)
You have to do Pythagorean theorem:

"a" and "b" are the legs. In this case 7 is a leg and x is a leg
"c" is the hypotenuses, which is 19 here
so...
a = 7
b = x
c = 19
Plug the numbers above into the equation:


Isolate x by subtracting 49 to both sides:


To solve for x you have to take the square root to both sides of the equation:

x = 17.6635
x = 17.7
