7. Find the angle between two forces acting on an object
of 55 pounds and 60 pounds given that the resultant
force is 103 pounds. Round to the nearest tenth. (Hint: write force 1 as a vector in the direction of the positive
x-axis and force 2 as a vector at an angle with the positive x-axis.)

Which rational number could be graphed between -4 and -5

What is the ratio of the length of an object in yards to the length of the same object in miles?

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
