Answer:

for the second part its d+2.5d+d-4

Step-by-step explanation:

The part of the expression represents the total amount each friend pays is  d+2.5d+d-4.

An expression is combination of variables, numbers and operators.

Each friend pays for the entrance fee, a booklet of ride tickets, and a meal ticket.

The entrance fee costs d dollars.

A booklet of ride tickets costs 2.5 times the entrance fee, which is 2.5d dollars.

A meal ticket costs $4 less than the entrance fee, which is (d - 4) dollars.

Therefore, the total amount each friend pays is:

d + 2.5d + (d - 4)

Simplifying the expression, we get:

4.5d - 4

Hence,  d+2.5d+d-4 is the part of the expression represents the total amount each friend pays.

Answer:

1. One solution

2. No solution

Step-by-step explanation:

1.Step 1: Subtract 2x from both sides.

5x+3−2x=2x−3−2x

3x+3=−3

Step 2: Subtract 3 from both sides.

3x+3−3=−3−3

3x=−6

Step 3: Divide both sides by 3.

3x  + -6

3        2

x=−2

Answer:

1)One solution

2)No solutions

Step-by-step explanation:

To solve this for the first one you should add both sides by three to get the constants on one side.

5x+3+3=2x

Combine like terms.

5x+6=2x

Get x to one side by subtracting 5x on each side.

6=-3x

Solve for x.

x=6/-3 or x=-2

Which means one solution.

To solve the second one you should o all the steps above, but to find:

8=3

Which is not true, so no solutions.

Answer:

8 inches

Step-by-step explanation:

The square has 4 sides and each one measure 2 inches since all side are the same on squares.

2*4=8

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

If the square is 2in that means every side is 2in and we know that a square has 4 sides. So what I would do is 2 * 4 and that equals 8 inches

Choice 3

Answer:

x = 6

Step-by-step explanation:

4(x + 2) + 2x = 44

~Distribute left side

4x + 8 + 2x = 44

~Combine like terms

6x + 8 = 44

~Subtract 8 to both sides

6x = 36

~Divide 6 to both sides

x = 6

Best of Luck!

Answer:

Step-by-step explanation:

If x is the first integer, then the fourth integer is x + 3. The sum of these is 33, so

x + (x + 3) = 33

2x + 3 = 33

2x = 30

x = 15

Step-by-step explanation:

x=15

Answer:

Even when the answer is not complete, most likely yes, she was cheated.

Step-by-step explanation:

The question does not include how a packet looks, however since the total egg count is 46 units, this number is only divisible by 2 and 23.

So unless each egg packet contains 2 or 23 eggs, any other size would mean a packet had less eggs than expected.

Usually eggs come in packs of 6 or 12 units, so to sum 46 eggs or more you would need:

If 6 eggs per packet:

46/6 = 7,66 packets -> she must have bought 8 packets and should have 48 eggs, meaning there are 2 eggs missing.

If 12 eggs per packet:

46/12 = 3,83 packets -> she must have bought 4 packets and should have 48 eggs, meaning there are 2 eggs missing.

That's why it is safe to assume some packets had less eggs than expected.

Answer:

54 miles

Step-by-step explanation:

Just divide the 27 miles to the half hour and you will see how many miles the boat travelled. In 27 miles in 2 hours is 13.5 miles so we figured out what we get in two hour so to find out for the half an hour you do the same thing

Answer:

6.75 miles.

Step-by-step explanation:

1/2 is 1/4 of 2 hours, so you'd take 1/4 of 27 (which is 27/4) and you would get 6.75.

If that explanation is a little difficult to understand, let me know and I will rephrase!

Answer:

15c

Step-by-step explanation:

3c x 5c =

3 x 5= 15

15c

the easiest way to do this problem is take away the c's in the expression and add them to your answer at the end which you would just be multiplying 5 x3 which = 15 then you would put the c next to the 15 so the answer would be 15c

Answer:

Edge of a cube (l)=25cm.

⇒  Volume of a cube =(l)3

                                     =(25)3

                                     =25×25×25

                                     =15625cm3

Answer: C, B, A, D

Step-by-step explanation:

1. option C

f(x) = 2x² - 1

f(-1) = 2(-1)² - 1

     = 2(1) - 1

     = 2  - 1

     =   1

2. option B

f(x) = 2x - 5

11  = 2x - 5

16 = 2x

8 = x

3. option A

f(x) = 2x - 5

f(3) = 2(3) - 5

     = 6 - 5

     =   1

4. option D

f(x) = x² + 7

f(-2) = (-2)² + 7

      =   4 + 7

      =  11

Answer:

The unit rate is 3 pounds per gallon.

Henry's likely error could have been that he multiplied instead of dividing.

Step-by-step explanation:

Given the rate  1/3 pound / 1/9 gallon, this can be written in the unit rate by dividing 1/3 pound by 1/9 gallon. First, we will evaluate 1/3 divided by 1/9 and the unit will be in pound per gallon.

1/3 divided by 1/9 can be written as

[tex]\frac{1}{3} \div \frac{1}{9}[/tex]

This then becomes

[tex]\frac{1}{3} \times \frac{9}{1}[/tex]

[tex]\frac{1}{3} \times \frac{9}{1} = \frac{9}{3} = 3[/tex]

Hence, the unit rate is 3 pounds per gallon.

Henry's likely error could have been that he multiplied instead of dividing. That is, he multiplied 1/3 by 1/9, Such that he gets

[tex]\frac{1}{3} \times \frac{1}{9}[/tex]

[tex]\frac{1}{3} \times \frac{1}{9} = \frac{1}{27}[/tex]

Hence, the 1/27 pound per gallon he got.

Answer: D

Step-by-step explanation:

Answer:

The equation Alejandra should write to represent the new line should be

y-3 = 2(x-10)

Step-by-step explanation:

The equation Alejandra wrote for the line her teacher sketched is

y-3 = 1/5 (x-10).

This can be related to the equation of a line in point slope form. The equation of line in point slope form

is

y - y₁ = m (x - x₁)

Where (x₁, y₁) is a point on line

and m is the slope of the line.

Hence, for the equation Alejandra wrote

The line went through point (3,10) and the slope of the line is 1/5.

Now, from the question

The teacher changed the line so it had a slope of 2, but still went through the same point. That is, the line still went through point (3,10).

In the new line the teacher sketched, the values of x₁ and y₁ remain the same but the value of the slope (m) has changed.

The slope of the new line is 2, that is, m =2.

Therefore,

The equation that represents the new line is

y-3 = 2(x-10)

Hence, the equation Alejandra should write to represent the new line should be y-3 = 2(x-10).
