Answer:
7 pieces of homework
Step-by-step explanation:
This is an algebra problem. We first need to set up our algebra equation and we are going to find X (The amount of homework Richard submitted)
The algebra equation would be
X+X+2=12
*Combine like terms*
2X+2=12
Subtract 2 to both sides
2X=10
X=5
That means that Richard did 5 pieces of homework. We are not done yet because we want to find the amount of homework Isaac did. Earlier in the problem, it said that Issac did 2 more pieces of homework than Richard. Take Richard's number, 5 and add to 2 to it to get 7 pieces of homework.
Step-by-step explanation:
using Pythagoras a²+b²=c²
HOWEVER you know the hypotenuse
so it's rearranged to either c²-b²=a² or c²-a²=b²
so 13²-11²
so 169-121
this makes 48
square root 48 is 6.90 inches
this rounds up to <u>7</u><u> </u><u>Inches</u>
The mixed number is 4 5/12.
keeping in mind that a function does not have any X-Repeats, that is, the 1st coordinate in every pair never repeats, well, in this case, all of them have no X-repeats, that means all of them are functions. However, only one-to-one functions have an inverse that is also a function.
A one-to-one function is one that has no X-repeats as well as no Y-repeats, so each pair in the set has no coordinate repeats, Check the picture below.
