Question

can you help me solving these problems ​

Answer 1

yes, of course

7. 1/x² is (1/5)*(/1.25)

6.25.

X² √6.25

x is 2.5

8. product of mean = product of extreme. 5x = 0.75(8)

5x is 6.

x is 6/5 is 1.20

10.x=2

y=1

x² is 2^2 is 4.

y² is 1^1 is 1

4-1 is 3.

4+1 is 5

3:5.

9. x is 5

y is 2

8(5): 9(2)

40 : 18

40:18 after reduced 20:9
