Answer:
Step-by-step explanation:
14...................................
11 2/3 pages in 15 minutes
- 35/3 ⇔ 15
- 35/3 ÷ 15 ⇔ 15÷15
- 35/45 ⇔ 1
- 7/9 ⇔ 1
7/9 pages per min
Option B
15....................................
5 2/3 meters in 1/3 hours
- 17/3 ⇔ 1/3
- 17 ⇔ 1
- 17 meters per hour
Correct option is B
Answer:
JK = 42 , KL = 78
Step-by-step explanation:
JK + KL = JL , substitute values
4x + 6 + 7x + 15 = 129 , that is
11x + 21 = 120 ( subtract 21 from both sides )
11x = 99 ( divide both sides by 11 )
x = 9
Then
JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42
KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78
To visualize better, look at it like this:
First, see if you can simplify 3/2. You can't, so leave it like that.
The rule for exponents is you subtract the exponent from the bottom (r) from the exponent on the top ()
Put that on the top, and you get
Using the Pythagorean theorem the length of x is 15.6 cm rounded to the nearest tenth.
