I believe it is A
Step-by-step explanation:
Use the formula:
Y-yo=m(x-xo)
Answer:
x = 9
Step-by-step explanation:
Since we know that the triangle is a right triangle we also know that the angle would be 90 degrees
However we are only given 56 and 3x+7
Let 3x+7 be u
We know that 56+u=90 so solve for u
u=90-56
u = 34
Now u = 3x + 7 so,
3x + 7 = 34
solve for x,
3x=34-7
3x=27
x=27/3
x=9.
I do believe it would be a 2.2
80 since he starts off with 38 stamps then gains 6 each month for 7 months (6x7=42) so 42+38=80
