6x + 12 = 10x − 4 1. Solve for x using two different methods
Answers
Answer:
x=53/4 or 4x=53
Step-by-step explanation:
First move the variable to the left-hand side and change its sign.
6x+12-10x=-41 to 6x-10x=-41-12
Then collect the like terms
6x-10x=-41-12 to -4x=-41-12 which equals to -4x=-53
Now you divide both sides of the equation by -4
-4x=-53 to x=53 over 4 then if you want you divide which gives you x=13.25
Second way:
Kind of the same thing as the first one
Move the variable to the left-hand side and change its sign
6x+12=10x-41 to 6x=12-10x=-41
Then you collect the like terms
6x-10x=-41-12 to -4x=-41-12
Now you multiply both sides of the equation by -1
-4x=-53 to 4x=53

Answer:
1. 1/12
2. 4/15
Step-by-step explanation:
1.
3/4 - 2/3
first, you need to set both of the denominators to the same digit by multiplying both the numerator and denominator by the same number
same number meaning the denominator of the other fraction
multiply 3/4 by 3/3
= 9/12 (3x3 and 4x3)
multiply 2/3 by 4/4
= 8/12 (2x4 and 3x4)
9/12-8/12= 1/12
How much of the whole pizza does he take for lunch?
answer: 1/12 of the pizza
2.
(same thing)
2/3 - 2/5
10/15 - 6/15= 4/15
How much of the whole cake did she eat after school?

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 35 problems. Each problem is worth either 5 points or 2 points. How can you set up a system of equations to find how many problems of each point value are on the test?
Let x = the number of questions worth 5 points.
Let y = the number of questions worth 2 points.
Answers
Answer:
Step-by-step explanation:
5x+2y=100
x+y=35
x=10
y=25
y - the number of 2 points worth problems
The test has 29 problems.
x+y=29
The test is worth 100 points.
5x+2y=100
The system of equations:
x+y=29
5x+2y=100
The solution:
-2x-2y=-58. | x (-2)
5x+2y=100

The bridge is 307 4/5 m long
Her steps are 3/10 m long
Divide the length of the bridge by the length of her steps
First change the 307 4/5 to 8/10 so we have a common denominator
(307 8/10)/(3/10)
Next change 307 8/10 to an improper fraction
Multiply the whole number by the denominator than add the numerator
(3078/10)/(3/10)=1,026/10
Now divide the numerator by the denominator
1,026/10=102 6/10
Which simplifies to 102 3/5
Bridgette had a whole pie. She ate 1/4 of the pie for a snack and ate another 25% of the pie for dessert. What fraction of the pie did Bridgette NOT eat?
Answers
Answer:
1/2
Step-by-step explanation:
Bridgette ate 1/4 of the pie, and 25% of the pie.
25% is converted to 1/4.
1/4 + 1/4 = 1/2.
1 - 1/2 = 1/2.
Bridge did NOT eat 1/2 of the pie.
Answer:
1/2
Step-by-step explanation:
She ate 50%
1/4 is the same as 25%
So 25% + 25% is 50%.
100%-50% is 50%
50% as a fraction is 1/2
