Answer:
400/1000×100%
40% is the percent of decrease from 1,000 to 400.
132=5x-8
5x=-132-8
5x=-140
X=
Answer:
d.) 2
Step-by-step explanation:
If you were going to solve the second part of the equation you would distribute and since we want the number we chose to equal 8, so the sides will be equivelent and their will be infinite solutions, we have to account for the *4 so if we do 8 ÷ 4 we will have the number we should use for infinite solutions
8÷4=2
You can also check it by putting 2 in the equation
4x + 8 = 4(x+2) now distribute the 4
4x+8=4x+8
Answer:
C
Step-by-step explanation:
When we speak about the least common multiple, we are talking about the lowest number in which these given values are a factor of
Firstly, I would like to consider the number parts only I.e 3, 12 and 15. Using the long division l.c.m method, the lowest common multiple of these is 60.
In the options, there are two options carrying 60. How do we know which is correct? We simply look at the alphabets and try the long division again.
The highest powers of x and y is the 3rd power and hence gives their lowest common multiple.
Please check the attachment for the long division.
Equation 1. The rate of change is 3. In equation 2, you must divide each side by 2, giving you a rate of 5/2, which is 2.5. And 2.5<3
