There different bcuz the denominator is the bottom number when u multiply or divide a fraction when u find a common number out of the 2 bottom ones
there alike bcuz they both r numbers in common with the number u r working with.
Answer:
1. First choice, 1/2
2. First choice, 1/2
Step-by-step explanation:
3 odd numbers on a dice, so 3/6 = 1/2
12 numbers, 1- 12, the even numbers are 2, 4, 6, 8, 1-, and 12. 6 out of 12 = 6/12 = 1/2
1. 3x ≤ 9
Divide 3 on both sides.
3/3 = 1 9/3 = 3
x ≤ 1
Your line graph should have a little line like this: | and with the number 1 under it.
It will be a shaded in circle since it's greater than, less than, and you goes to infinite.
2. 4x - 3 ≥ 13
Add 3 to both sides
4x ≥ 16
divide 4 into both sides
x ≥ 4
3. 4x - 3 < 13
same thing as 2
add 3 onto both sides
4x < 16
x < 4
this one is a bit different when you are using a line graph, you are going to do a opened circle, do not shade it in and then draw back.
4. 5x + 10 > 14x - 8
add 8 onto both sides.
5x + 18 > 14x
subtract 5x.
18 > 9x
x > 9
5. 2x - 6 < 2
add 6 to both sides
2x < 8
divide by 2,
x < 4
6. 2x - 5 ≤ x - 2
add to onto both sides.
2x - 3 ≤ x
subtract x onto both sides
-3 ≤ -x
This is crucial, any time you are dividing by a negative number you will always flip the sign.
x ≥ 3
7. 3x - 14 ≥ 2 - 5x
add 5x on both sides
8x - 14 ≥ 2
add 14 on both sides
8x ≥ 16
divide both sides by 8
x ≥ 2
I will let you do the last 3 on your own, but I hope you got the overall gist of it.
Answer:
8 feet
Step-by-step explanation:
4 times 8 is 32 and 5 times 8 is 40 and the difference is 8
