4/3x - 4 = 5 + x
Can you help me?

Answers

Answer 1
X=27


Dhahshahshhahsnjdnsja
Answer 2
Answer: x = 27

Multiple both sides by the equation of 3:
4x - 12 = 15 + 3x

Move the variable to the left and change the sign: 4x - 3x - 12 = 15

Move the constant to the right hand and change the sign: 4x - 3x = 15 + 12

Collect like terms: x = 15 + 12

Get the answer: x = 27

Cadesia has $42.70, which is 175% of the amount that Alisha has. How much money, in dollars, does Alisha have?

Answers

The amount of money she will have is 100%. So, you divide 175 by 100 and you get 1.75. Then, you divide 42.70 by 1.75 and get 24.4. So, Alisha has $24.40

Answers

Answer:   31

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

A base is any substance that reacts with an acid to form a salt and water only. This means that metal oxides and metal hydroxides are bases.

Some bases are soluble in water. An alkali is a soluble base - it dissolves in water to form an alkaline solution. For example:

copper oxide is a base but it is not an alkali because it is insoluble in water
sodium hydroxide is a base and it dissolves in water, so it is also an alkali
Example

Explain why all alkalis are bases but not all bases are alkalis.

Alkalis are soluble bases, but only some bases are soluble in water, so these are not alkalis.

Neutralisation reactions

Neutralisation involves an acid reacting with a base or an alkali, forming a salt and water.

Reactions with metal oxides

In general:

acid + metal oxide → salt + water

For example:

sulfuric acid + copper(II) oxide → copper(II) sulfate + water

H2SO4(aq) + CuO(s) → CuSO4(aq) + H2O(l)

Reactions with metal hydroxides

In general:

acid + metal hydroxide → salt + water

For example:

nitric acid + sodium hydroxide → sodium nitrate + water

HNO3(aq) + NaOH(s) → NaNO3(aq) + H2O(l)

Aqueous neutralisation reactions

Remember:

acids in solution form hydrogen ions, H+
solutions of alkalis contain hydroxide ions, OH-
Acid-alkali neutralisation reactions involve the reaction between hydrogen ions from the acid, and hydroxide ions from the alkali:

H+(aq) + OH-(aq) → H2O(l)

Pure water is neutral (its pH is 7). A neutral solution can be produced if the correct amounts of acid and alkali react together.

Neutralisation reactions in solution can be generalised to hydrogen ions reacting with hydroxide ions to form water.

To find the value of x for which the line passing through points F(3-2x, 12) and G(x + 9, 7) is vertical, we need to determine when the slope of the line is undefined.

The slope of a line can be calculated using the formula:
slope = (change in y-coordinates)/(change in x-coordinates)

In this case, the change in x-coordinates is (x + 9) - (3 - 2x), which simplifies to 4x + 6.
The change in y-coordinates is 7 - 12, which is -5.

For a vertical line, the slope is undefined, which means the change in x-coordinates must be zero. Therefore, we set 4x + 6 = 0 and solve for x:

4x + 6 = 0
4x = -6
x = -6/4
x = -3/2

So, the value of x for which the line passing through points F(3-2x, 12) and G(x + 9, 7) is vertical is x = -3/2.

Answers

Answer:

1. x = 59°

2. ∠1 = 123

3. ∠2 = 57

4. ∠3 = 57

5. ∠4 = 123

6. ∠5 = 123

7. ∠6 = 57

8. ∠7 = 57

9. ∠8 = 123

Step-by-step explanation:

∠1 = ∠4 = Vertically opp. angles = 2x + 5

∠2 = ∠3 = Vertically opp.angles

∠3 = ∠6 = Alternate interior angles

∠4 = ∠5 = Alternate interior angles

∠5 = ∠8 = Vertically opp. angles

∠6 = ∠7 = Vertically opp. angles = x - 2

Therefore,

∠1 = ∠4 = ∠5 = ∠8 = 2x + 5 ∠2 = ∠3 = ∠6 = ∠7 = x - 2

By angle sum property,

∠1 + ∠2 = 180°

2x + 5 + x - 2 = 180

3x + 3 = 180

3x = 177

x = 177 ÷ 3

x = 59

Now, 2x + 5 = 123

x - 2 = 57

Step-by-step explanation:

y-intercept: (0,1)

rate of change: 2/3

Y-intercept: I found this because the y-intercept is when x=0, and where the line crosses through the y-axis.  So, we can see that the y-intercept is (0,1)

Rate of change: The rate of change is another word for slope, or rise/run, so we can see, from point (0,1), that the rise is 2 units up and 3 units to the right to another point where the line crosses a whole number point.

Hope this helps :)

So its difficult to show

Y= X-6 so what ever x is, y is six less than that so

X= -4 Y= -10

X= 0 Y=-4

X=4 Y=0

X=8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that

X=-4 Y= -5

X=0 Y= -2

X=4 Y=1

X= 8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= -2

Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.

Y= 2+ 1/4x  so whatever x is y is 1/4 of x add 2

X=-8 Y= 0

X= -4  Y = 1

X=0 Y=2

X=4 Y=3

X=8 Y=4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Do this method for 9

y = 2x -3 so whatever x is, y is  2 times that -3

y=2x +1 so whatever x is y is 2 times that +1

y= 2x so whatever x is y is 2 times that

Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them

Make sure to label each line
