Answer:

- 180

Step-by-step explanation:

let the blank be n , then

[tex]\frac{n}{10}[/tex] = - 18 ( multiply both sides by 10 to clear the fraction )

n = - 180

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:

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:

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: They traveled 3,184.733333333333

Step-by-step explanation: Do 238,855 divided by 75 (The three keeps going on forever).

mark the other guy brainliest because he is correct it is B or 3,184.73 (the 3 has a line over it)

238,555 ÷ 75 = 3,184.733333333

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:

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).

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.

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

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:

By looking at the slope

Step-by-step explanation:

Let's use these equation: y = 2x + 3 and y = 2x - 9

You know that those two equations are parallel because the slope is the exact same!

But, if we rewrite those equations to: y = -2x + 3 and y = 1/2x - 9

You can now see that the equations are perpendicular because the slopes are Opposite Reciprocal. The slopes have opposite signs (pos./neg.) and are reciprocal numbers: 2 = 1/2
