Answer:
d = 11
Step-by-step explanation:
Isolate the variable (d). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 5 to both sides
2d - 5 (+5) = 17 (+5)
2d = 17 + 5
2d = 22
Next, divide 2 from both sides
(2d)/2 = (22)/2
d = 22/2
d = 11
11 is your answer for d.

A percentage is a comparison to 100, so
250% = 250/100 = 25/10 = 5/2
5/2 = 2 1/2 or 2.5

Answer:
103
Step-by-step explanation:
1 centimeter is 10 millimeters
540÷10=54cm
49+54=103cm
2/5+1/2^2
2/5+2/4
multiply the first fraction by four and the second fraction by five to get the common denominator of 20
8/20+10/20=18/20
reduce
9/10
hope I helped !
