The percentage of increase is 100%. Let me know if you need an explanation.
1. You can add 7 units to both sides of the scale so it becomes a balance between x on the left and 21 on the right.
x ___ 21
1A) The only number from the set that will keep the balance is x ∈ {21}
1B) The number on the right (21) will be more than x for x ∈ {0, 1, 7, 14}
1C) The number on the right (21) will be less than x for x ∈ {28, 30}
2A) (x +x +x) +(2 +4) = 102
3x +6 = 102 . . . . . . . . simplified equation
2B) Solving the equation, you have
3x = 102 -6
x = 96/3 = 32
The number that could be a value of x is 32.
Answer:
77°F
Step-by-step explanation:
C = 5/9 (F - 32)
25 = 5/9 (F - 32)
-----------------------
5/9
45 = F - 32
+32 +32
------------------
77=F
The answer is 126 degrees
