Alexandra has $15 to buy drinks for her friends at the baseball game. Soda

EleoNora [17]

Answer:

C

Step-by-step explanation:

write an equation for the costs:

if x is the number of sodas

and y is the number of waters

2.75x + 2y <= 15

(<= is less than or equal to)

if we substitute 3 for y

we get 2.75x + 2(3) <= 15

2.75x + 6 <= 15

2.75x <= 9

9 / 2.75 = 3.2727

however, you cannot buy part of a soda

so, round to 3

you also cannot buy negative sodas

so, the answer is C

A company conducted a survey to see whether its new toothpaste was morepopular with children or adults. Of the children surveyed

Naily [24]

Given: The information provided in the table shown

To Determine: From the options provided, the correct option that best describe the information given in the table

Solution

Given that 28% of the children used toothpaste. From the table

$Children(toothpaste)=\frac{0.07}{0.25}=\frac{7}{25}\times100=28\%$

Let us calculate the percentage of adult that used toothpaste

$Adult(toothpaste)=\frac{0.08}{0.75}=\frac{8}{75}\times100=10.667\%\approx11\%$

Hence, a smaller percentage of adults (about 11%) use the toothpaste.

The correct option is OPTION C

31 - 8a = 5 ( - 4 - 5a )

timama [110]

Answer:

Step-by-step explanation:

$31 - 8a = 5(-4 - 5a)$

First, on the right-hand side of the equation, let's distribute the $5$ to each term in the parenthesis:

$31 - 8a = -20 - 25a$

Now, let's move all the terms with an $a$ to the left-hand side, and everything else to the right-hand side of the equation:

$-8a + 25a = -20 - 31$

Let's combine like terms:

$17a = -51$

Finally, let's divide each side by $17$ to get $a$ by itself on the left-hand side of the equation:

$a = -3$
