I need to know the amount the that the uniform costs
I think it’s 1.5 times 10 then it will answer 15
So if you have r^2 + 4s and r=4 and s = 1.5 r^2 is 4^2 which is 16 and 4s is 1.5 x 4 which is 6 so you do 16 + 6 which is 22 so the correct answer is a.
If 10t = 9
t = 9/10 (as a fraction)
This is equivalent to 0.9
New answer is -0.9. step by step in the comments
