Answer: -4.5, but only if the phrase "five twice the sum . . ." means 5*2*(the sum of . . .). "five twice" is confusing, so please check the question.
Step-by-step explanation:
5*2*(X + 3) = 3*(2X - 1)
10X + 15 = 6X -3
4X = -18
X = -18/4
X = - 4.5
Step-by-step explanation:
-3x - 4 < 2
-3x < 2 + 4
-3x < 6
x < 6/ - 3
x < - 2
The number in brackets represents the percentage change
1.045
the 1 shows that it is an increase and the .045 shows the percent
for example 1.55 would be 55% increase and 1.555 would be 55.5% increase
The number is 21 because 2 is 1 doubled, and 2+1 is 3.
