Answer:
~ -4x+4y+10
Explanation:
~ We have to collect like terms such as all the x’s, y and the normal numbers.
~ Then add like terms together: x-5x, 4y plus nothing, 3+7
~ After adding them, you should get -4x+4y+10.
Sum of the angles of any quad =360
then y+(x+2)+(x-2)+(x-10) = y +3x -10 =360 (by adding both sides by 10)
y + 3x =370 ;.... eq 1
the sum of each two opposite sides in a quad inscribed in a circle =180
then (x+2)+(x-2)=180
therefore 2x =180
therefore x=90 (sub in eq 1)
y+3*90 =y +270 = 370 (subtracting both sides by 270)
therefore y=100
then measure angle B=100 degrees
A=92 degrees
C=88 degrees
D=80 degrees
The solutions are x=5,-1<span />
Answer:
90
Step-by-step explanation:
I am Sure that this is right
108 divided by 1.2 is 90
Sorry if it's wrong :(
Answer:
40%
Step-by-step explanation:
The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original. An increase of 5 percent would indicate that, if you split the original value into 100 parts, that value has increased by an additional 5 parts. So if the original value increased by 14 percent, the value would increase by 14 for every 100 units, 28 by every 200 units and so on. To make this even more clear, we will get into an example using the percent increase formula in the next section.
