Answer:
d = 40.44
Step-by-step explanation:
Simplifying
25.14 = d + (-15.3)
25.14 = d + -15.3
Reorder the terms:
25.14 = -15.3 + d
Solving
25.14 = -15.3 + d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-1d' to each side of the equation.
25.14 + -1d = -15.3 + d + -1d
Combine like terms: d + -1d = 0
25.14 + -1d = -15.3 + 0
25.14 + -1d = -15.3
Add '-25.14' to each side of the equation.
25.14 + -25.14 + -1d = -15.3 + -25.14
Combine like terms: 25.14 + -25.14 = 0.00
0.00 + -1d = -15.3 + -25.14
-1d = -15.3 + -25.14
Combine like terms: -15.3 + -25.14 = -40.44
-1d = -40.44
Divide each side by '-1'.
d = 40.44
Simplifying
d = 40.44
I think 12 minutes because there is 60 minutes in a hour and 15% of 60 is 12
6×(1×5)=(6×1)×5
6×5=6×5
30=30
Always do the brackets first.
Follow BEDMAS
B = Brackets
E = Exponent
D = Division
M = multiplication
A = Addition
S = Substruction
If 60% of a number is 75, we have to know the following:
60%=3/5.
3/5 of 75 is 45.
Therefore, 60% of 75 is 45.
The answer is A because it can be put into the equation: y= 3x+10
