X=12 because 73-3x=61-2x so add 3x to both to make 73=61+X then subtract 61 from both to get 12=X
I’m pretty sure the answer is 21.6
Answer:
Step-by-step explanation:
Using the information provided we can create two different equations for this system. The first of which would be Fred's overall weight, while the second equation would be Fred's and Barney's combined weight. These equations would be the following...
F = 2B - 40
320 = F + B
As requested I will not solve the system of equations and leave them as they are.
3^2 + 10^2 = 109
square root of 109 = 10.4403065089
One and four hundred thirteen thousandths in standard form would be <u>1.413 x 10^0.</u>
