Answer:

x=5

Step-by-step explanation:

pls heart and give brainliest

1. Simplify both sides of the equation

3/5 (x−10) = 18 − 4x − 1 ( 3/5 )(x) + ( 3/5 ) (−10) = 18 + − 4 x + − 1 (Distribute)

3/5x + − 6 = 18 + − 4x + − 1 3/5 x − 6 = (−4x) + (18+−1) (Then Combine Like Terms)

3/5 x−6=−4x+17 3/5 x−6=−4x+17

2. Add 4x to both sides

3/5 x−6+4x=−4x+17+4x 23/5 x−6=17

3. Add 6 to both sides

23/5 x−6+6=17+6 23/5 x=23

Step 4: Multiply both sides by 5/23.

( 5/23 )*( 23/5 x)=( 5/23 )*(23)

x = 5

Therefore the answer to this equation is "x = 5"

Answer:

Slope = 1

Equation: y= 1x + 1 or y= x + 1

Step-by-step explanation:

The slope is one because the rise over run from point (-1,0) to (0,1) is 1/1, and 1/1 is equal to 1. This means in the form y=mx + b the slope would be put in for m. y= 1x + 1. The plus one is because the line crosses the y axis at y = 1. When you are writing the equation technically you do not need to write it as y= 1x +1 you can just do y = x + 1 because there is only 1 x.

Answer:

The answer should be A. [tex]x \in (-\infty,\, 2)[/tex].

Step-by-step explanation:

Start with the second inequality, which is more straightforward than the first. Add [tex]3[/tex] to both sides of this equation to separate [tex]x[/tex] from the numbers:

[tex]x - 3 + 3 \le -1 + 3[/tex]. The direction of the inequality sign shall stay the same.

[tex]x \le 2[/tex].

On the other hand, simplifying the first inequality takes a bit more work. Start by dividing both sides by [tex](-3)[/tex]. However, keep in mind that dividing or multiplying both sides of an inequality with a negative number will invert the direction of the inequality sign. For example, the left-hand side of an inequality might have been greater than the right-hand side. When both sides are multiplied with a number less than zero, the new left-hand side would become smaller than the new right-hand side.

Because [tex](-3)\![/tex] is a negative number, dividing both sides of the first inequality inequality by [tex](-3)[/tex] will turn the "greater-than" sign into a "less-than" sign.

The inequality used to be:

[tex]-3\, (x + 2) > 15[/tex].

After dividing both sides by the negative number [tex](-3)[/tex], it becomes:

[tex]\displaystyle \frac{(-3)\, (x + 2 )}{(-3)} < \frac{15}{(-3)}[/tex].

[tex]\displaystyle (x + 2) < -5[/tex].

[tex]x < -7[/tex].

The question connected the two original inequalities with "or". Therefore, the conditions will be satisfied as long as either of at least one of the two inequalities is true. Note, that [tex]x < 2[/tex] is true whenever [tex]x <-7[/tex] is true. Therefore, any real number that is smaller than [tex]2[/tex] will meet the requirements- not just those that are smaller than [tex](-7)[/tex].

The corresponding interval will be [tex](-\infty,\, 2)[/tex].

Answer:

The equation has two answers

X = 0

X = 2

Step-by-step explanation:

The answer is absolute value or positive or negative, So it is

[tex] |x - 1| = 1[/tex]

[tex] |x - 1| = - 1[/tex]

We solve the equations and the answer is obtained

Hey there!

|x - 1| = 1 

TRANSLATE:

x - 1 = 1 or x - 1 = -1

SOLVING for: x - 1 = 1

x - 1 = 1

ADD 1 to BOTH SIDES

x - 1 + 1 = 1 + 1

CANCEL out: -1 + 1 because it give you 0

KEEP: 1 + 1 because it help solve for the current x-value

NEW EQUATION: x = 1 + 1

SIMPLIFY IT!
x = 2

Thus, your answer is: x = 2

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
SOLVING for: x - 1 = -1

x - 1 = -1

ADD 1 to BOTH SIDES

x - 1 + 1 = -1 + 1

CANCEL out: -1 + 1 (the LEFT SIDE) because it give you 0

KEEP: -1 + 1 (the RIGHT SIDE) because it give you the current x-value

NEW EQUATION: x = -1 + 1

SIMPLIFY IT!
x = 0

Thus, your answer is: x = 0

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
Therefore, your overall answer is:

x = 2 or x = 0

Good luck on your assignment & enjoy your day!

Answer:

28%

Step-by-step explanation:

Let number of children be 2x, then number of adults be 3x

Total number is 5x

Let number of children under 10 be 7y, number of children be 3y,

then total number of children is 10y

so 2x = 10y, x = 5y, y/x = 1/5

younger children = children under 10, number is 7y

so the % is 7y/5x = 7/5 * y/x = 7/5 * 1/5 = 7/25 = 28/100 = 28%

Answer:

I think it is the 3.76 I am 85%sire

Answer:

YEAH IT IS :D

Step-by-step explanation:

First you need to get 1 pound. 2 pounds is 3.76 divide it by 2 and get 1.88. Multiply it by so you can get 3 pounds: 1 x 3 = 3 pounds. 1.88 x 3 is 5.64. Now to get 4 pound you add 1.88 again to 3 pounds to add a pound and you get 7.52. Now add 1.88 to 4 one more time to get 5 pounds: 4 + 1 = 5 pounds. And 7.52 + 1.88 = 9.40. Now you checked the whole table and they are right so yes it is proportional to the weight of apples!

If i did it right...im not sure if i did...but it should be: - 2.5 = x

Step-by-step explanation:

4.5 (8 - x) +37 = 103 - (7.5x + 60)

(36 - 4.5x) + 37 = 103 - (7.5x + 60)

     + 4.5x                   + 4.5x

36 + 37 = 103 - (12x + 60)

73 = 103 - (12x + 60)

- 103  - 103

-30 = -12x - 60

+ 60         + 60

30 = - 12x

/-12    /-12

- 2.5 = x

Answer:

3.55

Step-by-step explanation:

This is simply combining like terms.

First, lets evaluate the terms separately.

x = 8 - (-2.25)

x = 8 + 2.25 (Negative signs cancel out)

x = 10.25 (Combine like terms)

y = 6 - 4.2 - (-4.9)

y = 6 - 4.2 + 4.9 (Negative signs cancel out)

y = 6.7 (Combine like terms)

Now, lets plug in these values to x - y.

(10.25)  - (6.7)

3.55

The value of x - y is equal to 3.55.

We know that:

[tex]1. \space\ V_{Rectangular \space\ prism} = 10 \text\] units^{3}\\\\2. \space\ L_{Small \space\ cube} = \frac{1}{2} \space\ units\\\\ 3. \space\ V_{Small \space\ cube} = L ^{3}[/tex]

Step-1: Find the volume of the small cube.

[tex]V_{Small \space\ cube} = L ^{3}[/tex]

[tex]V_{Small \space\ cube} = (\frac{1}{2}) ^{3}[/tex]

[tex]V_{Small \space\ cube} = (\frac{1}{2}) (\frac{1}{2}) (\frac{1}{2})[/tex]

[tex]V_{Small \space\ cube} = \frac{1}{8} \space\ units^{3}[/tex]

Step-2: Divide.

[tex]\frac{10}{\frac{1}{8} }\\\\ \Rrightarrow(10)(8)\\ \\ \Rrightarrow 80[/tex]

Hence, 80 cubes can be fit in the rectangular prism.

volume of rectangular prism = 10 units³

volume of each cube = [tex]\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2} = \frac{1}{8} units^3[/tex]

required cubes = [tex]\frac{10}{ \frac{1}{8} }= 80[/tex]
