Which of the sets shown includes the elements of set Z that are both odd numbers and multiples of 7?

Equation: w = 112 + 8t Which input results in an output of 176? What is the output in the ordered pair (4, 144)?

Answer:

8
144

Step-by-step explanation:

Generally, the single variable on the left side of the equation is the "output" or dependent variable, while any other variables on the right side of the equation are considered to be independent variables, or "input."

So, we assume your first question is asking for the value of t that makes w=176. Put the values in the equation and solve for the unknown.

w = 112 +8t

176 = 112 + 8t

64 = 8t . . . . . . . subtract 112

8 = t . . . . . . . . . divide by 8

The input for an output of 176 is 8.

__

Ordered pairs are always written as ...

(input, output)

So, (4, 144) means the output is 144 for an input of 4.

A survey was given asking whether people like dogs and/or cats. 153 said they like dogs 191 said they like cats 56 said they lik

lapo4ka [179]

Answer:

There were 362 people surveyed

Step-by-step explanation:

* Lets explain how to solve the problem

- A survey was given asking whether people like dogs and/or cats

# 153 said they like dogs

# 191 said they like cats

# 56 said they liked both cats and dogs

# 74 said they don't like cats or dogs

- We need to find how many people were surveyed

* Lets find the number of who likes dogs only and the number who

likes cats only

- The number who likes dog only (cats only) is the difference between

the number who likes dogs (cats) and the number who likes both

∴ The number who likes dogs only = 153 - 56 = 97

∴ The number who likes cats only = 191 - 56 = 135

- The total number of people were surveyed is the sum of the number

who likes cats only and who likes dogs only and who likes both and

who doesn't like both

∵ The number who doesn't like dogs or cats is 74

∴ The total number = 97 + 135 + 56 + 74 = 362

* There were 362 people surveyed

Question 374756: Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels

Dvinal [7]

Let the number of hours = X

Multiply the speed of each train by the number of hours (x) and add them together to equal the total miles:

75x + 95x = 238

Simplify:

170x = 238

Divide both sides by 170:

x = 238/170

x = 1.4 hours.

Check:

75 x 1.4 = 105 miles

95 x 1.4 = 133 miles

105 + 133 = 238 miles

It will take 1.4 hours ( 1 hour and 24 minutes).
