Answer: c. getting heads on a coin toss and rolling a 5 on a die
Step-by-step explanation:
Answer: x= 10
Step-by-step explanation:
l= 40
w=20
P=l+w+l+w
120=5x-10+2x+5x-10+2x
120= 14x-20
120+20=14
140=14x
x=10
Answer:
A = 3000(1 + .06/12)^120
strange the question did not want you to calculate the amount
that was given....
the interest is 5,458.19 - 3000 = 2,458.19
Step-by-step explanation:
Let's eliminate x. To achieve this, mult. the 2nd equation by 2, obtaining
-8x + 2y = 10. Now add this result to the first equation:
8x-2y= -10
-8x + 2y = 10
---------------------
0
The two equations actually represent the same line. Without an x- or a y-value, we cannot solve for the value of the other variable. There are infinitely many solutions.
