Answer:
1. x=2
2. x= 0.33
Step-by-step explanation:
1.So to start off you have a coefficient for 2 so you have to find what 2 to the power of 2 is =4 so then you have your new problem 4x+5=13 next you need to get 4x by itself so
-5 -5
then you have 4x=8. you divide by 4 on both sides
4. 4
so then you get x=2
2.So same here find what 3 to the power of 2 is =9
New equation 4x-1=9x+4x-4. Then combine like terms on the right you cant do it on the left because that is a separate part and those dont merge like terms so
9x+4x = 13x
new equation. 4x-1=13x-4
next subtract 4x on both sides
13x-4x=9x
new equation. -1=9x-4
next add 4 to both sides
-1+4= 3
new equation. 3=9x
so then divide 9 on both sides
3÷9= 0.33
x= 0.33
Hope this made sense and helps
Answer:
True.
Step-by-step explanation:
Let me clear it to you by an example:
if you take n=1,3,5,7,...... which are odd numbers
then adding 1 with them will give you n+1=2,4,6,8.... which are even numbers.
That's how, if an integer n is odd, then n+1 must be even.
Similarly, if you let n as even numbers, then n+1 will be odd.
Answer:
<em>The answer is 2.5 times The no of students who said that hip hop is their favorite kind of music </em>
Step-by-step explanation:
Let the total no of sixth grade students be n
At a school 40% of the sixth grade students said that hip hop is their
favorite kind of music
Let the number of students who like the <u><em>hip hop</em></u> be h
∵ h = 40 % of n
h = 40/100 × n
n = 100/40 × h
n = 2.5 × h
∴<em> The total no of sixth grade students = 2.5 times The no of students </em>
<em> who said that hip hop is their favorite kind of music </em>
