first we represent the unknowns using variables:
let x = measure of angle 4
let 3x+4 = measure of angle 3 (from the second statement)
then we set-up the equation. since the angles form a linear pair, their sum is equal to 180 degrees. therefore,
x + 3x + 4 = 180
4x + 4 = 180
4x = 176
x = 44 degrees (measure of angle 4)
3x + 4 = 136 degrees (measure of angle 3)
Caillan's pocket money increased 20-15=5 dollars per week, or to 20-15=1.33 of it's original amount. This is a 33% increase.

36 and 100 are both square numbers.
However, only 100 is within the given range.
Answer:
2
Step-by-step explanation:
solve the parentheses (6*3m)(6*5) so 18m +30 = 66, subtract 30 to both sides. 18m =36 and divide by 18 to both sides m=2
