Answer:

3+6×(5+4÷2)-7  

Step-by-step explanation:

To solve the expression use order of operations.

Right now the expression solves to:

3+6×5+4÷2-7                  6* 5 = 30

3 + 30 + 4÷2-7                4 ÷ 2 = 2

3 + 30 + 2 - 7                   Add and subtract left to right.

33 + 2 - 7

35 - 7

28

To make it solve to 38, add parenthesis:

3+6×(5+4÷2)-7                (5+4÷2) = 7

3+6×(7)-7                        6*7 = 42

3 + 42 - 7                        Add and subtract from left to right

45 - 7

38

Describe all the positive integers that would make [(1/2|4] less than (1/2)7
Zielflug [23.3K]

Answer:

The only positive integers would be anything less than 3. So 1 or 2 would work

Step-by-step explanation:

If something that is already being raised to a power, gets raised to another power, those powers add up. So if it were (\frac{1}{2} ^{2} )^{2}, the exponents would add which would make it (\frac{1}{2}^{4} ).

In the case of your question, if 'n' was 2 it would be to the power of 6 making it less than to the power of. 1 could also work

If y is 5 when x is 2.5 and y varies directly with x, find y when x is 10
ikadub [295]

Answer:

If x varies directly as y, then x=ky. y=5 and x=2.5 are substituted into x=ky to find k.

2.5=5k

k=2.5/5

k=5.

K =5 is substituted in x=ky to find y where x is 10.

x=5y

10=5y

y=10/2

y=2
