Answer:
24 and 21 are the two numbers
Step-by-step explanation:
let n represent the unknown number
let n-3 represent the second unknown number
n+n-3 = 45
2n-3=45
2n=45+3
2n=48
n=48/2
n=24
n-3=21
CHECK: 24+21=45
.˙. the first number is 24 and the second number with a difference of 3 is 21
(8+12) > side > |8-12|
20 > side > 4, Then 4 cm is the solution.

−2(6x+5)=74
Simplify both sides of the equation.
−2(6x+5)=74
−2 x 6x−2 x 5=74
−12x−10=74
Add 10 to both sides.
−12x−10=74
+10 +10
−12x=84
Divide both sides by -12.
−12x
=
84
/−12 /-12
x=-7

For this question, this might help.
17.47 degrees is 17 + 0.47 degrees
If you are using minutes instead of decimal degrees, multiply the fraction by 60. So,
0.47 degrees * 60 minutes per degree= 28.2 minutes
Now you have 17 degrees 28.2 minutes
but you can replace fractions of a minute with seconds
0.2 minutes * 60 seconds per minute= 12 seconds
So the answer for
17.47º is equal to 17º 28' 12".
I hope this helps.
