Answer:
x=8, y=-1
Step-by-step explanation:
The figure is said to be a rectangle, which means opposite sides have to be equal in length. From this, we can write a system of equations:
5x-2y=42
2x+3y=13
There are a number of ways to solve this but I'll go with elimination--that means you need to try to remove one variable first by manipulating the equations and solve for the other variable. Then you use the solution to solve for the variable you initially removed. That sounds confusing, but let me show you how to do it.
If you multiply the first equation by 3 and the second equation by 2, you'll have have:
15x-6y=126
4x+6y=26
Now, we can add these two equations. The y will cancel out, so we can easily solve for x.
19x=152
x=8
Use this value of x to substitute back into either of the original equations to find y.
5(8)-2y=42
40-2y=42
-2y=2
y=-1
This is a right angle.
So... 7z+3z=90
10z=90
Z=9
The larger angle is thus 7(9)=63 degrees
Answer:
360 degrees total, 90 degrees each
Step-by-step explanation:
a rectangle's angles add up to 360 degrees, so if you divide 360 by 4, each angle is 90 degrees and all right angles are equal to 90 degrees
The absolute values:
| - 14 | = 14
| - 9 | = 9
14 - 9 = 5
|| - 9 | - | - 14 || = | 9 - 14 | = | - 5 | = 5
Answer:
The distance between the given numbers is 5.
