The answer out of the choices that you have given me is C. Because you are adding 2 and 3 and y is going to be the quotient so that's the answer.

Answer:

A. The sum of 2 and the quotient of 3 and y.

Step-by-step explanation:

We have been given an expression: $2+3\div y$ . We are asked to choose the correct statement about our given expression.

We will use order of operations (PEMDAS) to answer our given problem.

P = Parenthesis.

E = Exponent.

M = Multiplication

D = Division

A = Addition

S = Subtraction

According to order of operations division comes before addition, so our expression will be: $2+(3\div y)$ , which is the sum of 2 and the quotient of 3 and y.

Therefore, option A is the correct choice.

Consider the Inequalities X >7 and X < 12 select all the values that satisfy both Inequalities

Maksim231197 [3]

Answer:

9;10

Step-by-step explanation:

What we can first do is make them into one double sided inequality and then interpret it from there.

After combining them we get: 7<x<12

This means that any number between 7 and 12 can be picked.

Keep in mind, this means that 7 and 12 cannot be picked, they have to be in between.

Therefore, we get our aswers of 9 and 10!

Sally can paint a room in 8 hours while it takes steve 7 hours to paint the same room. how long would it take them to paint the

77julia77 [94]

Rate for Sally is 1 room per 8hrs
rate for Steve is 1 room per 7hrs

combined rate:
1/8 + 1/7 = 1/T
7/56 + 8/56 = 1/T
15/56 = 1/T
56/15 = T
3 11/15 = 3 hrs 44 min

The sum of the digits of a three-digit number is 11. If the digits are reversed, the new number is 46 more than five times the o

lara [203]

Answer:

731

Explanation for problem:

"The sum of the digits of a three-digit number is 11."

x + y + z = 11

The three digit number = 100x + 10y + z

The reversed number = 100z + 10y + x

" If the digits are reversed, the new number is 46 more than five times the old number."

100z + 10y + x = 5(100x + 10y + z) + 46

100z + 10y + x = 500x + 50y + 5z + 46

combine on the right

0 = 500x - x + 50y - 10y + 5z - 100z + 46

499x + 40y - 95z = -46

"the hundreds digit plus twice the tens digit is equal to the units digit,"

x + 2y = z

x + 2y - z = 0

Three equations, 3 unknowns

x + y + z = 11

x +2y - z = 0

-----------------Addition eliminates z

2x + 3y = 11

From the 2nd equation statement, we know that the 1st original digit has to be 1

2(1) + 3y = 11

3y = 11 - 2

3y = 9

y = 3 is the 2nd digit

then

1 + 3 + z = 11

z = 11 - 4

z = 7

137 is the original number

Check solution in the 2nd statement

If the digits are reversed, the new number is 46 more than five times the old number."

731 = 5(137) + 46

731 = 685 + 46
