Answer:
84 miles in 12 hour
Step-by-step explanation:
12/4 = 3
3*28=84
"two less than 3/2 of a number (x) is no more than 5 1/2"
3/2x-2</5 1/2 (</ means less than or equal to)
simplify
1.5x-2 </5.5
+2 both sides
1.5x</7.5
÷1.5 both sides
x</5

"the sum of two times a number (x) and -2 is at least 8"
2x+-2>/8 (>/ means greater than or equal to)
2x-2>/8
+2 both sides
2x>/10
÷2 both sides
x>/5

"seven subtracted from 4 times a number (x) is more than 13"
4x-7>13
+7 both sides
4x>20
÷4 both sides
x>5

"four added to 3 times a number (x) is less than 19"
3x+4 <19
-4 both sides
3x <15
÷3 both sides
x <5

Answer:
it would take 65 hours to produce all of the order.
Step-by-step explanation:
1. you already would figure out that 26 hours=4 cases or 6.5 hours per case of hairbrushes.
2. You would figure out that 26+26 is 52 so 52 hours for 8 cases
3. Then you remember u have 8 cases of hairbrushes now. Set up a mental equation where you can solve in your mind: if I need 10 cases, but have figured out I only calculated 8, how much more would I still need to meet the order?
4. After mentally solving the hypothetical problem, you then would conclude you needed 2 more cases from 8 to equal 10.
5. you then divide 26 hours per 4 cases and you get 13 hours for 2 cases.
6. finally you multiply 26+26+13 which you would get 65 as the answer
Answer:
Yes
Step-by-step explanation:
An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point.
