9/13 is not a fraction that can be simplified: the two numbers don't have a divisor in common.
Let's bring all the other fractions into their simplest form too:
A.6/10=3/5
B. 2/3 This is the simplest form already
C.36/52 =18/26=9/13 ( I divided both numbers by 2 each time)
.... and we don't have to look further, we have already found the right answer: 9/13 is equivalent to 36/52.
I don’t know a thing about math and I should be doing my exam but I’ll guess on this
Y=3x domain: (1,0,1,2) I’m too lazy to type the range
Y=x+2 domain: (-3,-2,2,3)
Y=-x domain: (-2,0,2,4)
Y=2x+1 domain: (-2,-1,0,1)
Answer:
2.89? Or 2.99 but because its rounded to nearest<em> hundreth </em>it would most likely be 2.89
Step-by-step explanation:
Answer:
x = 12 and x = -6
Step-by-step explanation:
First subtract 6x on both sides to get a 2nd degree polynomial equal to zero:
To complete the square, the formula is to divide 'b' by 2 and square the result. The general form for a 2nd degree polynomial of the variable 'x' is as follows:
For your case, b = 6. Therefore, the term that must be added and subtracted to our equation is:
Add and subtract 9 to our equation to get:
The first three terms form a perfect square, we have:
What multiplies to equal 9 but adds to equal -6? That would be -3 and -3. Therefore:
Add 81 to both sides to get:
We want to take the square root, but recall a square root has a positive and negative branch. Therefore we have two solutions:
Answer:
A. x = 2y
64x + 132y = 1040
B. adult ticket = $8
student ticket = $4
Step-by-step explanation:
x = adult ticket
y = student ticket
A. an adult ticket is 2 times a student ticket, therefore, x = 2y
64(price of adult ticket) + 132(price of student ticket) = 1040
B. to find the price of each ticket, find the price of the student ticket (y) first since you have the adult ticket (x) by itself. Now you can substitute x = 2y into 64(x) + 132(y) = 1040. So you would get 128(y) + 132(y) = 1040. Next, combine both y to get 260(y) = 1040. Then divide both sides by 240 to get y which equals $4. Then you can easily find x which would equal $8
