9(3+c+4) use distributive property to simplify the expression

Answers

Answer 1

Answer:

The resultant of the given expression 9(3+c+4) using distributive property will be 63 + 9c.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given expression,

9(3+c+4)

⇒ 9(7+c)

By using distribution property,

⇒ 9(7)+9c

⇒63+9c

Hence "The resultant of the given expression 9(3+c+4) using distributive property will be 63 + 9c".

Pedro is building a spice rack with 4 shelves that are each 0.55 meter long. At the hardware store, Pedro finds he can only buy the shelving in whole meter lengths. Exactly how many meters of shelving does Pedro need? Since he can only buy whole number lengths, how many meters of shelving should he buy?

Answers

you multiply the numbers
4X0.55= 2.2

but since you need that 0.2 to complete the self you round up to 3

Pedro should buy $\boxed{\bf 3\text{\bf\ meters}}$ of the shelving.

Further explanation:

Procedure used:

The following steps are involved to find the value of $y\text{ unit}$ where $y$ is any real number.

1) If one unit is $x$ then multiply $y$ with $x$ .

2) The resultant number is $xy$ .

Given:

Pedro is building a spice rack with $4\text{ shelves}$ and length of each rack is $0.55\text{ meters}$ . He can only buy whole number of lengths.

Calculation:

Step 1:

The length of the shelf is $0.55\text{ meter}$ .

Multiply $4$ by $0.55$ to calculate the length of $4$ shelves.

$\begin{aligned}l&=\4* 0.55\n&=2.20\end{aligned}$

Here, $l$ represents the length of the $4$ shelves.

Step 2:

Pedro can only buy whole number lengths.

In the $\text{step }1$ we can see the length of the shelf is not appropriate as he can by only whole numbers.

Pedro needs exactly $2.2\text{ meters}$ of shelving.

Therefore, the number $2.20$ lies between $2$ and $3$ .

The number $2$ is not correct as the length should be at least $2.20\text{ meters}$ .

Therefore, Pedro should buy $3\text{ meters}$ of the shelving.

Thus, the required length of the shelf is $\boxed{\bf 3\text{\bf\ meters}}$ .

What is 1/3 added to 5/6

Answers

7/6
Change 1/3 to 2/6 in order to have a common denominator.
Then add the numerators (2 and 5) and keep the denominator.

The first thing to do is to make the denominators. Since 3 goes into 6, the first fraction should simply be doubled:
1/3 + 5/6 = 2/6 + 5/6
5 + 2 = 7
7/6

1/3 + 5/6 = 1 1/6 or 7/6

A grocery store so the six pack of bottled water for $3.79 a 12 pack for $6.89 which package cost The least per bottle explain your reasoning

Answers

Easiest way to find out the answer to this is to find out the price of every water bottle. To do that you have to divide the whole value by the amount of water bottles. (3.79/6 & 6.89/12) The first one should equal something around .63 each and the second should be around .57. Technically the second pack is cheaper than the other by around .6 cents.

Aaron received a $25 gift card for his birthday. He used it to download a game for $3.99and some songs for $0.99 each.
The following inequality models the relationship among the quantities in this scenario
where x represents the number of songs Aaron can afford to download:
25 ≥ 0.99 x + 3.99
Show all work to solve the inequality

Answers

25 ≥ 0.99x + 3.99

Subtract 3.99 to both sides:

21.01 ≥ 0.99x

Divide 0.99 to both sides:

21.22 ≥ x

x ≤ 21.22

So he can buy less than or equal to 21 songs.

$21 \geq x$

$25 \geq 0.99x + 3.99$

$25-3.99 \geq 0.99x + 3.99-3.99$ (Subtract 3.99 on both sides)

$21.01/0.99 \geq 0.99x/0.99$ (Divide 0.99 to isolate x)

21.01/ 0.99 is 21.222 bar, so round it to the nearest ones place, which is 21.

$21 \geq x$

Check:

$0.99(21)+3.99$ (Multiply)

$20.79+3.99$ (Add)

$24.78$ , which is $25.

After working for 24 hours,zoe made $234. After working for 40 hours, zoe made $390.predict how much she would make after 10 hours of work?

Answers

First you need to find money per hour. 234 ÷ 24 = 9.75; 390 ÷ 40 = 9.75; she makes $9.75 an hour. Multiply by ten; in 10 hours she'll make $97.5. Hope that helps!

Final answer:

To predict how much Zoe would make after 10 hours of work, we set up a proportion using the information given in the question. Cross multiplying and solving for x, we find that Zoe would make $97.50 after 10 hours of work.

Explanation:

To predict how much Zoe would make after 10 hours of work, we can use the information given in the question. We know that after working for 24 hours, Zoe made $234, and after working for 40 hours, Zoe made $390. To find out how much Zoe would make after 10 hours of work, we can use the concept of proportionality. We can set up a proportion using the number of hours worked and the amount earned:

24 hours / $234 = 10 hours / x

Cross multiplying, we get 24x = (10 * $234). Solving for x, we find that x = (10 * $234) / 24. Evaluating the expression, we find that x = $97.50.
