A=h(a+b)/2 solve for a

Answers

Answer 1
Answer:

Answer:

2A/h - b =a

Step-by-step explanation:

A=h(a+b)/2

Multiply each side by 2

2A =h(a+b)/2*2

2A=h(a+b)

Divide each side by n

2A/h = h(a+b)/h

2A/h = a+b

Subtract b from each side

2A/h - b =a+b-b

2A/h - b =a
Answer 2
Answer:

Answer:

((2A)/h)- b=a

Step-by-step explanation:

First get the 2 to the left by multiplying each side by 2. Then, get h to the right by dividing each side by h. Lastly, subtract b from each side.

A trapezoid has an area of 13.5 square inches. If the bases are 3 and 6 inches what is the height?

Answers

well the formula is : b1+b2/2 (h)

so the height would be solved as : 
13.5 = 3+6/2 (h)
13.5 = 9/2 (h)
h = (13.5)/(9/2)
h = (13.5) x (2/9)  *reciprocal*
h = (27) / (9)
h = 3

5p-p=4p. The question doesn't make sense because ther is no sign after the minus 6. If it is an X it would be -24p. If it is an add it would be -6+4p. If it was a - it would be -6-4p.

PLEASE HELP ME!! This assignment is already late!If d + 5 >= (greater than or equal to) 17, complete each inequality.

d >= ?

d + ? >= 20

d - 5 >= ?

Answers

d + 5 >= 17
We can subtract 5 from each side:
d >= 12
To get 20 on the right, we have to add 8 to each side (20-12=8).

d + 8 >= 20

To get d - 5 from the first expression (d + 5 >= 17) we have to subtract ten from each side (5-10=-5) and we get:

d - 5 >= 7
