Question

Need help don’t know what to do I’m confused

Answer 1

the last one is the answer h=2t-d distribute the 1/2 into the (d + h) you get t=1/2d + 1/2 h then multiply everything by the denominator of 2 this would give you 2t = d + h because the denominator of 2 on the d and h cancel out and leaves a 1 infront which is just d and h then i’d u switched the h and 2t across the equation they become the opposite sign -h = -2t + d since you don’t want -h switch all the signs leaving you with the answer h = 2t - d

Answer 2

Answer:

last option;  h = 2t - d

Step-by-step explanation:

t = 1/2(d + h)

t = $\frac{d}{2}$ + $\frac{h}{2}$

now multiply each side by 2 to eliminate denominator

2t = 2 ($\frac{d}{2}$ + $\frac{h}{2}$)

2t = d + h

h = 2t - d
