Hey there!
A quadrilateral has 360 degrees. So add all the degrees together to 360. 9x+1+5x-12+8x+61+90=360. 90 degrees is in the bottom left corner. Combine like terms. 22x+140=360. Subtract 140 from each side. 22x=220. Divide 22 on each side to get x=10. Plug in 10 for x in angle D. 5(10)-12=38. The measure of angle D is 38 degrees.
I hope this helps!
Answer:
5
Step-by-step explanation:
Take the number of markers and divide by the number in each package
70/15
4.6666repeating
Round to the nearest whole number to determine the number of packages
5
They will need to buy 5 packages
It would be 80% since it decreases 20% each year so 20*4 is 80 so it’s 80%
Divide the amount spent on utilities (285 dollars) over the total expenses (2376 dollars) to get...
285/2376 = 0.1199
which is approximate
Move the decimal over 2 spots to the right to go from 0.1199 to 11.99% which is the final answer (this is approximate as well)
Note: Moving the decimal over 2 spots to the right is the same as multiplying by 100. So that means 0.1199*100% = 11.99%
