The sum of twice a number and 15 is grater the 3

NNADVOKAT [17]

Answer:

x>-6

Step-by-step explanation:

The expression you need to solve for this is: 2x+15>3

For now pretend that the > is a = and solve as you normally would for x.

Subtract 15 from both sides

2x=-12

Divide by 2

x=-6

Put the > back in

x>-6

Kyle and his friends share some apple pie equally. Each person gets 7/5 of the pies. Which of the following shows a possible way

stiv31 [10]

Answer:

7 apples divided among 5 people

Step-by-step explanation:

Given

Apple shared equally

Portion of each person = 7/5

Required

A possible way that shows how the pies were shared.

Given that 7/5 is the ration of the pie to each individual (Kyle and his friends).

Provided that each individual got equal ration....

The ration can be divided into two

The numerator = 7

The denominator = 5.

The numerator shows the number of things that were shared.

Hence, 7 apples were shared.

The denominator shows the number of people involved.

Hence, 5 people were involved.

So, we can conclude that 7 apples were divided among 5 people.

From option A through D, only option B satisfied this analysis

Solve1 over 25 = 5^x ^+ 4. <br> x = -7/2<br> x = −6 <br> x = 9/2 <br> x = 2

Basile [38]

The equation seems to be

   1
-------- = 5 ^ (x + 4)
25

In that case, this is the solution, stept by step:

1) factor 25: 25 = 5^2

      1
=> ----------- = 5^(x + 4)
       5^2

2) invert 5^2

=> 5^(-2) = 5^(x+4)

3) Given that the bases are equal, the exponents also have to be equal:

=> - 2 = x + 4

3) transpose +4:

=> - 2 - 4 = x

=> x = - 6

Answer: - 6
