Answer:

x=9.5

Step-by-step explanation:

x+2(x+1)=68-3(x+3)

x+2x+2=68-3x-9

3x+2=68=59-3x

6x=57

x=9.5

this is isosceles triangle, so side AB and BC are the same !

9x-8 = 28

9x=36

x=4

Answer:

probably 4 since the sides are the same

Step-by-step explanation:

9x-8=28

28+8=36

9x=36

36÷9=4

x=4

Answer:

Percent increase = 30%

Step-by-step explanation:

Given that:

Old price of toy = £50

New price of toy = £65

Difference = New price - Old price

Difference = 65 - 50

Difference = £15

Percent increase = [tex]\frac{Difference}{Old\ price}*100[/tex]

Percent increase = [tex]\frac{15}{50}*100[/tex]

Percent increase = 0.3 * 100

Percent increase = 30%

Hence,

Percent increase = 30%

Answer:

[tex]\frac{6\times 10^2}{3\times 10^{-5}}[/tex] = 2 x 10⁷

Step-by-step explanation:

Given expression is [tex]\frac{6\times 10^2}{3\times 10^{-5}}[/tex]

The given expression is simplified as follows;

[tex]\frac{6\times 10^2}{3\times 10^{-5}} = (\frac{6}{3} )\times 10^{2-(-5)}\\\\(\frac{6}{3} )\times 10^{2-(-5)} = (\frac{6}{3} )\times 10^{2+5}\\\\(\frac{6}{3} )\times 10^{2+5} = 2 \ \times \ 10^7[/tex]

Therefore, the result of the given expression is 2 x 10⁷

The number of DVDs will be 304.5.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that In one day a store sold 3/4 as many DVDs as Blu-Ray discs. The total number of DVDs and Blu-Ray discs sold was 406.

The number of the DVDs will be calculated as below:-

Number = 406 x ( 3 / 4).

Number = 304.5

Therefore, the number of DVDs will be 304.5.

Answer:

The value of n is 7.

Step-by-step explanation:

For each teen, there are only two possible outcomes. Either they buy soda at least once each week, or they do not. Since they were selected randomly, the teens are independent of each other, which means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

In the binomial distribution, we have that n is the size of the sample. In this question, seven teens are randomly selected, which means that the value of n is 7.

Answer:

No X-intercept: √(x)+1

No Y-intercept:   √(x-1)

Answer:

The answer is [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

When we divide two fractions, we multiply the numerator by the inverse of the denominator. So

[tex]\frac{\frac{a}{5}}{\frac{3a}{10}} = \frac{a}{5} \times \frac{10}{3a} = \frac{10*a}{5*3a} = \frac{10a}{15a} = \frac{2}{3}[/tex]

The answer is [tex]\frac{2}{3}[/tex]

Answer:

2nd 6

3rd 9

10th 22

Step-by-step explanation:

1st 2(1) +1 = 3

2nd 2(2) + 2 =6

3rd 2(3) + 3 = 9

10th. 2(10) + 10 = 22

I think this is how you solve it

Answer:

You wrote:

2*x + 4 = 14

This is not an inequality, so i guess that you wanted to write something like:

2*x + 4 ≥ 14

Now, this means that the left equation is always equal to or larger than 14.

Now, which type of problem this may represent?

Well, 2*x + 4 should represent something that is larger than 14, only that.

Then we can write something like:

"You have 4 dinosaur toys, and in the toy store near your house, they sell packs of 2 dinosaur toys. If you want to have at least 14 dinosaur toys, how many packs can you buy?"

Now x represents the number of packs that you buy.

2*x is the number of dinosaurs in these packs

2*x + 4 is the total number of dinosaurs that you have, when you also count the ones that you previously had.

2*x + 4 ≥ 14

Is the inequality that represents the problem.

a+b+h=80

b=8+a

H=2A

a+8+a+2a=80

4a+8=80

a=18

Answer:

(a) $0.80

(b) 1.25 m

Step-by-step explanation:

(a) Put 1 where L is, and evaluate the equation.

... p = 0.8·1 = 0.8

The cost for 1 meter of rope is $0.80.

(b) Put 1 where p is and solve for L.

... 1 = 0.8L

... 1/0.8 = L = 1.25

The length of rope that costs $1 is 1.25 meters.

Answer:

Well that depends on where you buy it

Step-by-step explanation:

It could cost various things and you didn't add enough context for us to assume where you could have purchased the nylon rope

Answer:

If this is what your question is, yes the price of the burger is a function of the number of patties.

Step-by-step explanation:

This is because, the number of patties is the independent variable and the price is the dependent variable. A function can be written as y = f(x), here x is the number of patties. The price of the burger is y. I had this question that is also why I know this is right.

I hope this helps and have a nice day..

There is no direct relationship between the price of the burger and the amount of patties in it.

To determine if the price of a burger is a function of the number of patties, the following calculations must be performed:

First, the price of each hamburger must be divided by the number of patties it has.

Thus, it can be seen that there is no direct relationship between the price of the hamburger and the amount of patties in it.
