Answer:
50
Step-by-step explanation:
let the number be x
15% of x= 0.15x
0.15x=30
(divide both sides by 0.15)
x= 200
25% of 200 = 25/100 *200
= 50
Answer:
1. 9x+4<58
x<6
2. 1x-2>3
x>1
Step-by-step explanation:
1. 9x+4<58
First, you need to group all the like terms ( the group of numbers that have the same variable), Also remember that, when a positive number crosses an inequality symbol, it becomes negative.
9x<58-4
Then, subtract the two numbers.
9x<54
Divide x's coefficient by 54 and you have your answer.
x<6
2. 1x-2>3
First, you need to group all the like terms. Remember that, when a negative number crosses an inequality symbol, it becomes positive.
1x>3-2
Then, subtract the two numbers.
1x>1
1 divided by one is one, so
x>1
Answer:
5u + 6
Step-by-step explanation:
because 5u does not have any like terms, it stays on its own. the 2 and 4 can be added together because they are the same as eachother, leaving you with 5u + 6:)
hope this helps!
3/4 x -18 = 1/4 x -4
subtract 1/4 x from each side
3/4 x -1/4 x -18 = 1/4 x- 1/4 x -4
2/4 x - 18 = -4
add 18 to each side
1/2 x -18 + 18 = -4 + 18
1/2 x =14
multiply by 2 on each side
2* 1/2 x = 14 * 2
x =28
Answer: 1, 13 is the answer
