plz mark my answer as brainlist if you get it help ful .

Answer:

if these expression represent side lengths, then you simply add those three expressions, and that's the perimeter.

Step-by-step explanation:

I explore this idea a bit. obviously x < 5 (because 5-x has to be positive.

2x-5 > 0 is a requirement, also, so x > 2.5 is required.

Cris eats the least amount of cake.

A word problem is a few sentences describing a 'real - life' scenario where a problem needs to be solved by way of a mathematical calculation.

Given is that Luisa eats more cake than Cris. María eats more cake than Cris and less than Rosa, but she eats more than Luisa.

Let's assume that -

x > y                             ... (1)

w > z > y                         ... (2)

z > x                            ... (3)

We can write -

Maria > Luisa > Cris

Rosa > Cris

The inequality can be written as -

Maria > Luisa > Cris < Rosa

Therefore, Cris eats the least amount of cake.

Step-by-step explanation:

Answer:

18 tablespoons of blue paint; 3 batches

Step-by-step explanation:

For 1 batch of paint, she uses 2 cups of white paint and 6 tablespoons of blue paint.

She needs to mix blue paint using 6 cups of white paint.

6 cups is 3 times 2 cups, so she will be making 3 batches.

She also needs to use 3 times the amount of blue paint that she would use for 1 batch.

Since she uses 6 tablespoons of blue paint in 1 batch, she needs to use 3 times as much blue paint.

3 * 6 tablespoons = 18 tablespoons.

Answer: P = 2716.3448786 or about 2700

Step-by-step explanation:

The amount that need to invest, to the nearest hundred dollar is to be considered as the 2,700.

Since

The interest rate be like = 1.5% = 1.5% / 4 = 0.38%

The time period = 13 * 4 = 52

The future value = $3,300

The PMT is = $0

Now the following formula is used;

So,

= -PV(RATE,NPER,PMT,FV,TYPE)

After applying it, the present value should be $2,700

Answer:

$0.98

Step-by-step explanation:

Given data

Cost of sinuses apples = $9.8 for 10 pound

We want to find the cost per pound

Hence

if 10 pounds cost $9.8

  1 pound will cost x

cross multiply

x= 9.8/10

x= $0.98

Hence a pound will cost $0.98

Answer:

Step-by-step explanation:

2x+6 > -14

Subtract 6 from both sides

2x > -20

Divide both sides by 2

x > -10

The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Six more than twice a number is greater than negative fourteen.

Let x be the number. Then the equation will be

2x + 6 > - 14

Simplify the inequality, then the value of x will be

2x > - 20

x > - 10

The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.

Answer:

15 cups of paint

Step-by-step explanation:

I take it as you want to learn about the formula.

The quadratic formula is a formula where you can solve x for any quadratic equation in form  ax^2+bx+c=0.

The formula is x= [tex]\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex].

The +- means + or - for the 2 solution in each equation.

*All above information is what you need to know about the quadratic formula and solve for answer, but I will go a step further in my answer to prove the quadratic formula always work.

[tex]0=ax^2+bx+c[/tex]

[tex]0=(ax+\frac{b}{2})^2-\frac{b^2}{4}+c[/tex] (This step is completing the square)

[tex](ax+\frac{b}{2})^2=\frac{b^2}{4}-c[/tex]

[tex](2ax+b)^2=b^2-4ac[/tex]

[tex]2ax+b=+or-\sqrt{b^2-4ac}[/tex]

[tex]2ax=-b+ or -\sqrt{b^2-4ac}[/tex]

[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

This is my way of proving this formula although there are many other ways to do it too, if there is any questions, feel free to ask me in the comment :-).

Answer:

C. 39.6

good luck, i hope this helps :)

Answer:

It would be 21.6

Step-by-step explanation:

First 2% of 16000 is 320.

Now we take our wanted value of 22900 and subtract 16000 from it to get 6900.

We take our difference of 6900 and divide this by 320 and get 21.5625

That rounded to the nearest tenth is 21.6

Answer:

10 days

Step-by-step explanation:

Mr Datu can pay 8 workers for 15 days,

Then at the same rate he can pay 1 worker for the number of days = 15×8

                                                                                                                = 120

If he adds number of workers = 4

Then total number of workers = 8 + 4 = 12

With the same rate Mr Datu can pay 12 workers for number of days = [tex]\frac{120}{12}[/tex]

                                                                                                                 = 10 days

Therefore, Mr Datu can pay 12 workers for 10 days a the same rate.

Answer: 85.8g

Step-by-step explanation:

From the question, we are informed that 46.8g of sugar is needed to make 6 cakes. Therefore, the amount of sugar needed to make 1 cake will be:

= 46.8/6

= 7.8kg

Then, the amount of sugar needed to make 11 cakes will be:

= 7.8 × 11

= 85.8g

Answer: y = 11.25

Step-by-step explanation:

Mi espanol es terrible :l

Todos los angulos terminaran acompletando 90° grados

Entonces hagamos una ecuacion

3y + 4y + y = 90

8y = 90

Divide por 8

y = 11.25

Esta parte no es necesaria

Para ver si es verdad hagamos el math

3(11.25) = 33.75

4(11.25) = 45

y = 11.25

33.75 + 45 + 11.25 = 90

Answer:

[tex]x = 27[/tex]

Step-by-step explanation:

A shape exterior angles add up to 360.

[tex]3x + 4x + 2x + 40 + x + 50[/tex]

[tex]10x + 90 = 360[/tex]

[tex]10x = 270[/tex]
