In order to solve this question we first have to break down the terms.
Sum = Adding
Times = Multiplying.
The question states "3 times the sum of a number n and 12 is 45". In written form, it would be the following:
3(12+n) = 45
To solve this you first divide both sides by three and you'd be left with the following:
(12+n) = 15.
Then subtract 12 from both sides. Leaving you with:
n = 3
Answer:
(A) y = 24
Step-by-step explanation:
Given GDEF is a parallelogram and m∠E = 108°
To find: value of y
In ║grm GDEF,
m∠D + m∠E = 180° (Consecutive angles of parallelogram are supplementary)
3y° + 108° = 180°
3y° = 180° - 108°
3y° = 72°
y = 72°/3 = 24°
Therefore, option (A) is the correct answer.

Answer:
Option C. 15^2 + 20^2 = 25^2
Step-by-step explanation:from the question, we obtained the following:
The sides = 25, 15, 20
Since it is a right angle triangle, 25 is the longest side. Therefore their relationship is:
15^2 + 20^2 = 25^2
Answer: x=52/3
Step-by-step explanation:
x+2/3=18
x=18-2/3 ⇔ subtraction property of equality
x=54/3-2/3 ⇔ convert integer into fraction
x=52/3
Hope this helps!! :)
