5x -5.5 = -27.5

5x -5.5 = 27.5 + 10 = 37.5

27.5 x 2 = 55

27.5 + 10 = 37.5 x 2 = 75

Nina [5.8K]
<h2>Hello!</h2>

The answer is:

The man did consume two standard drinks in two hours.

<h2>Why?</h2>

According to the standard drink conversion, we know that each 12 ounce beer we have one (1) standard drink, and each 1.5 ounce shot of liquor, we have another standar drink.

Calculating we have:

DrinksConsumed=12Oz(Beer)+1.5Oz(Liquor)=1StandardDrink+1StandardDrink\\\\DrinksConsumed=1StandardDrink+1StandardDrink=2StandardDrinks

We have that the man did consume two standard drinks in two hours.

Have a nice day!

Sara wants to find the input value that produces the same output for the functions represented by the tables.
Naya [18.7K]

The input value that produces the same output value in both charts is 2. so the correct answer is option D.

<h3>What is a function?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

You are given two functions  f (x) = -0.5X +2 and g(x) = 2x - 3

x      f(x)

-3     3.5

-2     3

-1     2.5

0     2

1      1.5

2     1

3     0.5

The second table is given below:-

x      g(x)

-3      

-2      

-1      

0    

1      

2      

3      

We will put the points and will find the value of functions:-

g(-3) = 2(-3) - 3 = -6 -3 = -9

g(-2) = 2 -(-2) -3 = -7

g(-1) = 2( -1) -3 = -3

g(0) = 2 - 0  - 3 = -3

g(1) = 2.1 - 3 = -1

g(2) = 2.2 -3 = 1

g(3) = 2.3 -3 = 3

Hence the second table will be

x      g(x)

-3      -9

-2      -7

-1       -5

0       -3

1        -1

2       1

3       3

The input value that produces the same output value in both charts is 2.

In one minute, Evan can do nine less than four times the number of push-ups that Lucy can do. if they did 61 push-ups in all, ho
vagabundo [1.1K]

Evan does 33 more push-ups than Lucy

let x be the number of push-ups Lucy does , then

Evan does 4x - 9 push-ups

The total number of push-ups is 61

hence x + 4x - 9 = 61 has to be solved

that is 5x - 9 = 61

add 9 to both sides

5x = 61 + 9 = 70

divide both sides by 5

x = \frac{70}{5} = 14

Lucy does 14 push-ups and Evan does 4x - 9 =(4 × 14) - 9 = 47

Thus Evan does 47 - 14 = 33 more push-ups than Lucy
