Answer:
x=0
Step-by-step explanation:
13x-2 = 10x-2
Subtract 10x from each side
13x-10x-2 = 10x-2 -10x
3x-2 = -2
Add 2 for each side
3x-2+2 = -2+2
3x= 0
divide by 3
3x/3 = 0/3
x =0
Answer:
Step-by-step explanation:
first we turn ur mixed number into an improper fraction
1 1/4 = 5/4
the reciprocal of 5/4 can be found by just flipping it....so the reciprocal is gonna be 4/5
so 1 1/4 subtracted from its reciprocal is :
4/5 - 5/4 =
16/20 - 25/20 =
- 9/20 <====
I can not set up a 2 way table online but what they want is a collom of the information neatly laid out...
With the 9th graders in one collom and the 10th graders in the other
like this
9th grader 10th grader
# of students 32 40
# of participated 32 18
Draw this out with lines and it will be correct.
I hope this helps GOOD LUCK...this is tough math for a middle schooler.
Answer: Mark has 28 marbles while Don has 85 marbles.
Step-by-step explanation:
Let x represent the number of marbles that Mark has.
Let y represent the number of marbles that Don has.
If Don has 1 more than 3 times the number of marbles Mark has, it means that
y = 3x + 1
The total number of marbles is 113. It means that
x + y = 113- - - - - - - - - - - - 1
Substituting y = 3x + 1 into equation 1, it becomes
x + 3x + 1 = 113
4x + 1 = 113
4x = 113 - 1 = 112
x = 112/4
x = 28
y = 3x + 1 = 3 × 28 + 1
y = 85
Answer: It would of been $339.25
Step-by-step explanation: If you do the math 299 divided by 45 you will get 40 so now add 40 to 299 you will get $339 minus 50 cents will be 25 so $339.25 would be the original price of the bike.
