Questions 1-3 you have to multiply the whole number that many times of that power that is given.
Question 1. 2 x 2 x 2 x 2 =16
Question 2. 3 x 3 x 3 = 27
Question 3. 10 x 10 =100
Question 4. Braces
Question 5. 4+3 x 5 First you are going to multiply 3 x 5 =15. Second you add 15 + 4 = 19. Answer = 19. First you perform multiplying.
Question 6. You first add the 9+7=16 then divided that by 2 and you get 8. First you perform addition.
Question 7. First you have to do parentheses 12+6 =18 then divided 18 by 6 and you get 3. First you perform the parentheses.
Question 8. 8(11-6) First you subtract what is in the parentheses and you get 5 then you multiply 8 x 5 = 40. The last thing you perform in the multiplying.
Question 9. First you do the exponents. 4 x 4 =16 then 16 + 3 =19. The last thing you perform in the addition. Answer 19.
Question 10. First Subtract 5-3= 2 then you do 10 divided by 2 = 5. The last thing you perform is dividing. Answer 5.
Question 11. 8+7 x 4 First you multiply 7 and 4 = 28 then 28 + 8 = 36. Answer 36.
Question 12. 10-3+6-2 =7+6-2=13-2=11. Answer 11.
Question 13. 6+8 divided by 2. First add 6+8=14 divided by 2 = 7. Answer 7.
Question 14. You would have to do the distributive property. 6 x 14 = 84. Then multiply 6 x 1 = 6. Then subtract 84-6 =78. Answer 78.
Question 15. First subtract 6-2=3. Then do 3 x 3 =9. Next add 1 +7 =8. Then multiply 9 x 8 = 72. Answer 72.
Question 16. First subtract 18-6=12. Then 12 divided by 3 = 4. Answer 4.
Question 17.First you do exponents 3 x 3 = 9. Then add 16 + 9 = 25. Answer 25.
Question 18. First you do exponents 6 x 6 = 36. Then subtract 40 - 36 =4. Next add 4 + 7 = 11. Answer 11.
Question 19. First you do exponents 2 x 2 = 4. Then divided 24 by 4 = 6. Answer 6.
Question 20. First you do exponents 10 x 10 x 10 = 1000. 10 x 10 =100. 10 x 1 = 10. Next step is to multiply. 5 x 1000 = 5000 and multiply 3 x 10 = 30. Then the rest is addition. 5000+ 8+100+30+7 =5145. Answer 5145.
Sorry but I don't know about the last 2 question on the worksheet I hope this helped a lot.
Answer:
x=1, y=2
Step-by-step explanation:
x + 7y = 15
x + 2y = 5
Subtract the two equations
x + 7y = 15
-x - 2y =- 5
------------------------
0x +5y = 10
Divide by 5
5y/5 = 10/5
y =2
Now find x
x+2y = 5
x +2(2) = 5
x +4 = 5
Subtract 4 from each side
x-4+4 = 5-4
x = 1
1. Rename the mixed numbers with common denominators
2. Add the mixed numbers together to get 15 4/6
3. Subtract the sum from 26 to get 10 1/2
4. Since the only term left on the left is k so k=10 1/2
Car travelling to the east is at 104 miles per hour and the car travelling to the west is moving at 114 miles per hour
