Answer:
5
Step-by-step explanation:
Use PEMDAS to complete the problem
PE doesn't matter, there's not parentheses or exponents
MD=Multiplication and Division. Do 3*6=9, now your problem looks like 9-4
AS=Addition and Subtraction. 9-4=5
Answer:
Step-by-step explanation:
The way I like to think about it, with absolute value meaning the distance is
"find which number are 16 apart from 12". Which means 28 (to the right) or -4 (to the left).
More formally, applying the definition of absolute value,
Answer: 86 degree
Step-by-step explanation:
The Straight line is 180 degrees so if we minus 180 by the outward degree there will be the degree for inward degree
P: 95 degrees T: 160 degree S: 88 degrees R: 91 degree
The degree for the pentagon is 540 degrees so If I minus 540 by all the four inward degrees there will be the missing last degree
95 + 160 + 88 + 91 = 434 degree
540 - 434 = 106 degree
180 - 106 = 94 degree
So the last inward degree is 94
Finally, if I minus 180 by 94 (the way I used to find inward degree and to find outward degree for now) it equals 86 degree
so X is 86 degree
Sorry if this was too confusing:)
To eliminate x, you can multiply the second equation by 2. This will make -2x into -4x, so that 4x and 4x will be able to cancel out leaving you to solve for y.
To eliminate y, you can multiply the second equation by 3. This will make 3y into 9y, so that -9y and 9y will be able to cancel out leaving you to solve for x.
Hope this helped.
