Percent means out of 100 so 1%=0.01
so we multiply each decimal with 100 and get the decimal
0.03 times 100=3%
0.3 times 100=30%
0.045 times 100=4.5%
0.49 times 100=49%

Answer:
Step-by-step explanation:
4x-40=7(-2x+2) multiply inside the parenthesis with 7
4x - 40 = -14x + 14 export like terms to the same side of equation
4x + 14x = 14 + 40 add like terms
18x = 54 divide both side by 18
x = 3
Answer:
B. 21
Step-by-step explanation:
The fractions are there to just make the problem seem complicated, but just rewrite it without the fractions.
"What is a common multiple for 7 and 3?"
In this problem it's easy, all you have to do is guess and check.
A: A doesn't work. 7 is not a factor of 18.
B: B works! Both 3 and 7 are factors of 21.
C: C doesn't work. 7 is not a factor of 3.
D: D doesn't work. Neither are a factor of 4.
They only leave us with one solution, B.
