Answer:

6. 7.2 sq m

7. 5.17

8. 11.2

9. 17.70

10. 14

Step-by-step explanation:

6. 43.2 ÷ 6 = 7.2 sq m

7. 15.51 ÷ 3 = 5.17

8. 78.4 ÷ 7 = 11.2

9. 63.5 ÷ 10 = 6.35

6.35 + 11.35 = 17.70

10. x = be the number

x = 5y + 4. - equation 1

x = 6y + 2. - equation 2

By elimination method, subtact 2 equations

[tex] \: \: \: \: x = 5y + 4 \\ - \: x = 6y + 2[/tex]

It will give us

0 = -y + 2

y = 2

Since y=2, substitute the value of y in either equation 1 or 2 it will give you the same number

So, I used equation 1

x = 5(2)+4

x= 10+4

x = 14
