Answer:

Yes

Step-by-step explanation:

Multiply both sides by the reciprocal of 2/3 which is 3/2.

This will leave you with y = 54(3/2)

54(3/2) = 81

Therefore, y=81

What number is 1/10 as great as 7,962
yanalaym [24]
Assuming your question can be rewritten as:
"What number is 10% greater than 7,962"

7962 * 110% = itself + 10%
= 7962 * 1.10   <----- (1.10 = 110%)
= 8758.2

Need help with number 62 plz!
Montano1993 [528]

Answer:

All convert to terminating decimals.

Step-by-step explanation:

A decimal fraction will terminate if its denominator is a power of 2 or 5 or a product of such powers.

16 is the 4th power of 2, so all fractions that are some multiple of 1/16 will terminate.

SKIP # 14 SHOW ALL WORK PLEASE AND I WILL GIVE BRAINLY AND 77 points for it
babunello [35]

Answers:

11. 48%

12. 25%

13. 36%

15. 93%

16. 99%

17. 0.16%

18. 160%

19. 85%

Work for 19:

The chart is incorrect because it calculates 40% of 34 instead of 40 percent of x (we got 85% for our answer but I'm using x as the unknown number) results in the number of 34.

Percentage of 40% of what number = 34?

40% of what number = 34 is equivalent to: 40% × ? = 34

--------------------------

40% × ? = 34

? =

34 ÷ 40% =

34 ÷ (40 ÷ 100) =

(100 × 34) ÷ 40 =

3,400 ÷ 40 =

85

Proof:

If 40% × 85 = 34 =>

Divide 34 by 85...

... And see if we get as a result: 40%
