Answer:
2.5 right?
Step-by-step explanation:
Answer:
80°
Explanation:
All angles inside a triangle must add up to 180°
Answer:
(4,19)
Step-by-step explanation:
Cuz if u substitute these values in for the x and y in the equation, the equation would be true:
1.) 19 <em>= </em>7(4) - 9
2.) 9 <em>≠</em> 7(54) - 9
3.) 30 <em>≠</em> 7(-3) - 9
4.) 15 ≠ 7(2) - 9
As you can see, 1st equation is the only equation that's true.
Hope this helps!
If she uses all the cubes, its is 12.
1. One that is 20x1x1 cubes (20 is length, 1 is width, and 1 is height)
2. One that is 1x20x1 cubes
3. One that is 1x1x20 cubes
4. One that is 4x5x1 cubes
5. One that is 5x1x4 cubes
6. One that is 1x4x5 cubes
7. One that is 10x1x2 cubes
8. One that is 1x2x10 cubes
9. <span>One that is 2x10x1 cubes
10. </span>One that is 2x2x5 cubes<span>
11. </span>One that is 5x2x2 cubes<span>
12. </span>One that is 2x5x2 <span>cubes</span><span>

For this case, the first thing we must do is define variables.
We have then:
x: number of pens
y: number of pencils
We now write the system of inequations:
The solution to the system of inequations is given by the shaded region.
