Answer:
-2/12
Step-by-step explanation:
Given Rational Numbers are 4/7 and 13/7
Adding them we get 4/7+13/7
= (4+13)/7
= 17/7
Therefore, the Sum of 4/7 and 13/7 is 17/7.
Add 5/12 and -3/12?
Given Rational Numbers are 5/12, -3/12
Adding them we get 5/12+(-3)/12
= (5-3)/12
= -2/12
Answer:
0.75
Step-by-step explanation:
If she plans to jog 4.25 miles each day then 4.25 * 7 would equal 29.75. This is the first answer.
In order to get the second answer, we need to subtract 30.5 (What she needs to jog) over 29.75 (how much she is planned to job over the next 7 days). So 30.5 - 29.75 = 0.75
Here is the math I did to get 0.75:
= 30.5 - 29.75
= 30.5 + -29.75
= 0.75 (Answer)
It’s A
:) hope it’s right!!!
First you'll need to isolate the equations so that y is on one side.
y is already on the left side in the second equation, so let's do the same for the first equation.
x+3y > -3
1. Subtract x from both sides.
3y > -3-x
2. Divide both sides by 3.
y > -1-1/3x
Now you have two equations that you can graph.
- y > -1-1/3x
- y < 1/2x + 1
I'll try to explain how to graph them, but I'll also attach a graph.
y > -1-1/3x
- Go to -1 on the y axis and go down 1, over 3 units. The line will be a dotted line because > is not equal to as well. Since it is greater than, >, you will shade above the line you make.
y < 1/2x + 1
- Go to 1 on the y axis and go up 1, over 2 units. The line is also dotted because < is not equal to (≤). Since it is less than, <, you will shade below the line you make.
Answer is:
Here is the final graph.
The red line is y > -1-1/3x, the blue line is y < 1/2x + 1.
