in the problem (5x8) + 3^2(7) which step should you perform last

Answer:

Step-by-step explanation:

3x-11+6x-10+x=180

10x-21=180

10x=201

x=20,1

Answer:

x = 24

y = 10

z = 17

Step-by-step explanation:

4z - 32 = 36

4z = 68

z = 17

6x - 29 = 115

6x = 144

x = 24

36 + 115 = 151

180 - 151 = 29

3y - 1 = 29

3y = 30

y = 10

Answer:

Step-by-step explanation:

Step one:

given

Total money at hand=$25

cost of one popcorn=n $2.5

cost of drink= $1.5

total number of friends plus you= 4+1= 5

let the total amount spent be y

y= 5(2.5)+5(1.5)

y=12.5+7.5

y=20

The above shows that $20 is enough to cover the expenses, and there will be a balance of $5

Answer:

The correct answer is A

Step-by-step explanation:

I think you are trying to find corresponding sides. In the answer that you think it is, it says BC = DF. Well, is you look triangle ABC you see that BC is at the bottom. However, this differs from triangle DEF because EF is the bottom line. So if you look at the answer A, you see that it has the correct corresponding sides. I hope that helps :))

Answer:

If p - q = 10, then p = 10 + q.  Replace the other p with this:

q(2(10 + q) - 10) = 3600

q(20 + 2q - 10) = 3600

q(10 + 2q) = 360

The equilibrium point of a demand and supply function is the point where both functions are equal.

The equilibrium price is 40, and the corresponding demand is 30 supplies

Given

[tex]p- q = 10[/tex] --- the supply function

[tex]q(2p - 10) = 2100[/tex] --- the demand function

Make q the subject in [tex]p- q = 10[/tex]

[tex]q = p - 10[/tex]

Substitute [tex]q = p - 10[/tex] in [tex]q(2p - 10) = 2100[/tex]

[tex](p - 10)(2p - 10) = 2100[/tex]

Factor out 2

[tex]2(p - 10)(p - 5) = 2100[/tex]

Divide both sides by 2

[tex](p - 10)(p - 5) = 1050[/tex]

Open brackets

[tex]p^2 -10p - 5p + 50 = 1050[/tex]

[tex]p^2 -10p - 5p + 50 - 1050 =0[/tex]

[tex]p^2 -15p - 1000 =0[/tex]

Expand

[tex]p^2 -40p + 25p- 1000 =0[/tex]

Factorize

[tex]p(p -40) + 25(p- 40) =0[/tex]

Factor out p - 40

[tex](p+ 25) (p- 40) =0[/tex]

Solve for p

[tex]p = -25[/tex] or [tex]p = 40[/tex]

The price cannot be negative.

So: [tex]p =40[/tex]

Recall that:

[tex]q = p - 10[/tex]

[tex]q = 40 - 10[/tex]

[tex]q = 30[/tex]

Hence, the equilibrium price is 40, and the corresponding number of supplies is 30

Answer:

0.83

Step-by-step explanation:

add the hot, cold, and both sections together

The probability of people liking hot or iced coffee is 0.61. Therefore, option C is the correct answer.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, according to sales records at a local coffee shop, 75% of all customers like hot coffee, 30% like cold coffee and 22% like both hot and iced coffee.

People like only hot coffee = 0.53

People like only iced coffee = 0.08

Customers like hot or iced coffee =0.53+0.08

= 0.61

Therefore, option C is the correct answer.

Answer:

  18.8 cubic inches

Step-by-step explanation:

The formula for the volume of a cone is useful:

  V = 1/3πr²h

Where r is half the diameter, we can use r=d/2 to write this in terms of diameter:

  V = 1/3π(d/2)²h = (π/12)d²h

For the given dimensions, the volumes are ...

  large cone: v = (π/12)(4.5 in)²(5.1 in) ≈ 27.04 in³

  small cone: v = (π/12)(3 in)²(3.5 in) ≈ 8.25 in³

Then the difference in volume is ...

  (27.04 -8.25) in³ ≈ 18.8 in³

The larger cone has about 18.8 cubic inches more volume.

First Degree Equations

A first-degree equation can have one, none, or infinitely many solutions.

An equation like

2x + 3 = -x + 6

Has one solution: x=1

An equation like:

4x + 2 = 4x + 1

Has no solutions because when trying to solve for x we get:

2 = 1

This equality is false and no value of x can make it true

Finally, the equation:

3x + 2 = x + 2x + 2

Has infiniteyl many solutions, because when trying to solve it, we get:

2 = 2

Which is true regardless of the value of x

3x + 9 + 4x + x = ??

can be simplified as:

8x + 9 = ??

For this equation not having solutions, we should have 8x plus any number but 9 on the right side of the equation:

8x + 9 = 8x -3, or

8x + 9 = 8x + 4

3x + 9 + 4x + x = ??

can be simplified as:

8x + 9 = ??

If the equation has one solution, the only condition is that we should not have 8x on the right side. Thus any of those will do:

8x + 9 = 3x + 9

8x + 9 = -x + 5

8x + 9 = 0

3x + 9 + 4x + x = ??

can be simplified as:

8x + 9 = ??

For this equation to have infinitely many solutions, the right side must be exactly equal to the left side:

8x + 9 = 8x + 9

Answer: 24 schedules.

Step-by-step explanation:

Given data:

Courses planning to take = 4

Computer courses = 2

Courses from other areas = 2

Solution:

This problem can be solved using permutation.

For Computer science courses.

npr = n! / ( n - r )!

Where n = 4

r = 2

4p2 = 4!/( 4-2)!

= 4!/2!

= 12

For other courses.

Where n = 4

r = 2

4p2 = 4!/( 4-2)!

= 4!/2!

= 12

Fourth Option

Step-by-step explanation:

In order to find the answer to this question you need to change the mixed number into a improper fraction and then add by finding the least common denominator (LCD).

[tex]-\frac{3}{4} +2\frac{3}{4}[/tex]

Convert into improper fraction:

[tex]2\frac{3}{4} =4\times2=8+3=11[/tex]

[tex]-\frac{3}{4} +\frac{11}{4}[/tex]

Since how the denominators are the same you can just add numerators:

[tex]-3+11=8[/tex]

[tex]=\frac{8}{4}[/tex]

Reduce:

[tex]8\div4=2[/tex]

[tex]4\div4=1[/tex]

[tex]=\frac{2}{1}[/tex]

[tex]\frac{2}{1} =2[/tex]
