Answer:
17. 11x - 11y or 11x + (-11y)
18. -7.52 - 2.8 or -7.52 + (-2.8)
19. 41x - 21y - 6
20. -3y -8xy
Step-by-step explanation:
17. Use the distributive property.
18. Use the distributive property to multiply each number inside the parentheses by 0.4
19. Multiply each number inside the parenthese by 7.
20.Multiply each term in parenthese by y.
Ok, so what you want to do, is to start by adding the values together. So, she read an average of 36 pages for the first three days. So, you will multiply 36 by 3. Then, you will have 44 pages for the next three days, or 44 * 3. And finally, you have the last 10 pages. So, it is (36 * 3) + (44*3) + 10. So, 36 times 3 is 108, and 44 times 3 is 132. So, you now have 108 + 132 + 10. Add all of those values together, and your final answer is
250.
Answer:
X=35
Step-by-step explanation:
X=35 because a straight line is 180 degrees. Take away 60 degrees and you're left with 3x + 15 = 120. Simplify to 3x=105, and then divide 3x by 3. Do the same to the other side. X will now equal 35. Hope this helps :)
Answer:
True
Step-by-step explanation:
According to the attached formula:
apothem = side length / 2 * tan (180/number of sides)
apothem = 6 / 2 * tan (180/10)
apothem = 6 / 2 * 0.32492
apothem =
