5(-3)-3

-15-3

-18

Answer:

-9+2x

Step-by-step explanation:

Hey there!

3x - 5x + 5 = 20

• First COMBINE your LIKE TERMS

(3x - 5x) + (5) = 20

3x - 5x = -2x

• NEW EQUATION:

-2x + 5 = 20

• SUBTRACT by 5 on BOTH SIDES

Like: -2x + 5 - 5 = 20 - 5

Cancel out: 5 - 5 because that gives you a 0

Keep; 20 - 5 because it helps us solve for your x

**20 - 5 = 15**

• NEW EQUATION:

-2x = 15

• DIVIDE by -2 on BOTH SIDES

2x/-2 = 15/-2

Cancel out: -2x/-2 because that gives you 1

Keep: 15/-2 because it helps us solve for x (it also gives the value of “x”)

**AFTER SOLVING ABOVE WE FOUND OUR ANSWER**

Answer: x = -15/2 ✅

Good luck on your assignment and enjoy your day!

Answer:

4/5

Step-by-step explanation:

75% = 75/100 = 0.75 = 3/4

4/5 = 80/100 = 80% = 0.80

75 = 75% = 3/4 = 75/100

75%

80% - this is the biggest

75%

HOPE THIS HELPS

PLZZ MARK BRAINLIEST

Answer: 4/5

Step-by-step explanation:

75% = 75/100 same as 0.75

4/5 = 0.80

0.75 already in decimal

Therefore 0.80 is the greatest

Answer:

X= 1.5 Y= 2.5

Step-by-step explanation:

Answer:

(a) TRUE

(b) TRUE

(c)  FALSE

(d) TRUE

Step-by-step explanation:

" The "opposite" of any number is also known as it's " additive inverse" i.e. for any number 'a' the additive inverse is 'a' ".

(a) TRUE

Since let us consider any negative number '-5' then it's opposite is '5' since (-5)+5=0

(b) TRUE

this could be seen clearly from the number line.

(c) FALSE

this statement is false since we can take example of zero.

the opposite of zero is 0 but 0×0≠1.

(d) TRUE

since 0-0=0.Step-by-step explanation:

Answer:

The number 11 is not a solution for the given equation.

Step-by-step explanation:

We are given an equation with one variable. We can use simplifying processes to solve the equation.

[tex]3(x+6)=4x \ \ \text{Distribute the 3 through.}\\3x + 18 = 4x\ \ \ \text{Flip the equation.}\\4x = 3x + 18 \ \ \ \text{Subtract 3x from both sides.}\\\small\boxed{\bold{x = 18}}[/tex]

We can also substitute 11 for x and solve to see if the left side and right side of the equation equals itself.

[tex]3(11 + 6) = 4(11)\\33 + 18 = 44\\\small\boxed{\bold{51 \neq 44}}[/tex]

Therefore, 11 is not a solution for the given equation.

Answer:

[tex] \displaystyle \rm \longmapsto \:3(x + 6) = 4x[/tex]

[tex] \displaystyle \rm \longmapsto \:3x + 18 = 4x[/tex]

[tex] \displaystyle \rm \longmapsto \:4x = 3x + 18[/tex]

[tex] \displaystyle \rm \longmapsto \:4x - 3x = 18[/tex]

[tex] \displaystyle \rm \longmapsto \:x = 18[/tex]

[tex] \displaystyle \rm \longmapsto \:3(11 + 6) = 4(11)[/tex]

[tex] \displaystyle \rm \longmapsto \:33 + 18 = 44[/tex]

[tex] \displaystyle \rm \longmapsto \:51 = 44[/tex]

Answer:

0.33696

Step-by-step explanation:

Given that:

Probability of showing up head (p) = 0.6

Number of flips = number of trials = 5

Probability of getting more than 3 heads

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x> 3) = p(4) + p(5)

P(x = 4) = 5C4 * 0.6^4 * 0.4^1 = 0.2592

P(x = 5) = 5C5 * 0.6^5 * 0.4^0 = 0.07776

Hence,

0.2592 + 0.07776

= 0.33696

Following are the calculation to the probability:  

The probability to see the head [tex](p)= 60\%= 0.60[/tex]

Amount of flips = amount of tries = 5

Chances of getting and over three heads:

            [tex]\to P(x = x) = ^n C_x \times p^x \times (1 - p)^{(n-x)}\\\\\to P(x> 3) = p(4) + p(5)\\\\\to P(x = 4) = ^5 C_4 \times 0.6^4 \times 0.4^1 = 0.2592\\\\\to P(x = 5) = ^5 C_5 \times 0.6^5 \times 0.4^0 = 0.07776\\[/tex]

Hence,

                       [tex]\to 0.2592 + 0.07776= 0.33696 \approx 0.34\\\\[/tex]

Therefore, the final answer is "0.34"

Answer:

Ich weiß nicht =13

die Antwort -2 -4 (6p-5)

Step-by-step explanation:

Answer:

EZ PZ bruh

Step-by-step explanation:

First one, -25/4 ÷ -5 5/4

change the second mixed fraction into an improper one

=> -25/4 ÷ -25/4; dividing a number by itself gives you '1'

=> 1

second question,

=> -3/21 × -3; multiply the numerator with the other numerator, and since there is nothing given in the denominator of the second number mean its 1, hence multiply the denominator with the other denominator, and we get:

=> 9/21; we simplify this fraction and get: 3/7

Answer:

14°

Step-by-step explanation:

We know that ∠PQS is a right angle.

We also know that ∠PQR is 76°.

So, to find ∠RQS, we can do 90°-76° = 14°

x° = 14°

Answer:

[tex] \huge{ \boxed{ \bold{ \tt{x = 14 \degree}}}}[/tex]

Step-by-step explanation:

♨ First , let's know about complementary angles :

✎ Now, set up an equation and solve for x :

Move 76° to R.H.S ( Right Hand Side ) and change it's sign

➺ [tex] \sf{x \degree = 90 \degree - 76 \degree}[/tex]

➺ [tex] \boxed{ \bold{ \sf{x \degree = 14 \degree}}}[/tex]

Answer:

First Number is 13

Second Number is 27

Step-by-step explanation:

let x = first number

let 2x + 1 = second number

x + (2x + 1) = 40

3x + 1 = 40

    - 1      -1

3x = 39

/3      /3

x = 13

13 x 2 = 26 + 1 = 27

Answer:

5 apples

Step-by-step explanation:

First, we must find the cost of one apple

12/20 = the cost of one apple

= $0.60

Then, we divide 3 by the price of one apple

3/0.6 = amount of apple we can buy

= 5

Answer:

X = 8

Y = 32

Z = 16

Step-by-step explanation:

X + Y + Z = 56

Y = 2Z

X = Z – 8

Substitute the values from the second and third equation into the first equation:

Z – 8 + 2Z + Z = 56

Simplify

-8 + 4Z = 56

4Z = 64

Z = 16

So if Y = 2Z, Y = 2(16) = 32

And if X = Z – 8, X = 16-8 = 8

Answer:

x=6 2/3 So (6 2/3, 0)

Step-by-step explanation:

The [x] intercept of the line would be 20/3.

The general equation of a straight line is -

y = mx + c

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

We have the equation of the line as -

y = 4 - (3/5)x

We can write the equation as -

y = -(3/5)x + 4

For [x] intercept -

y = 0

-(3/5)x + 4 = 0

4 = (3/5)x

x = (4 x 5)/3

x = 20/3

Therefore, the [x] intercept of the line would be 20/3.

Answer:

[tex]y = -5x - 3[/tex]

Step-by-step explanation:

The data in the question are not properly presented.

See attachment for graph

To determine the graph, first we need to calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where x and y are corresponding values:

When x = -1; y = 2;

This implies [tex](x_1,y_1) = (-1,2)[/tex]

When x = 0; y = -3

This implies [tex](x_2,y_2) = (0,-3)[/tex]

So:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{-3 - 2}{0 - (-1)}[/tex]

[tex]m = \frac{-3 - 2}{0 +1}[/tex]

[tex]m = \frac{-5}{1}[/tex]

[tex]m = -5[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x-x_1)[/tex]

Where:

[tex]m = -5[/tex]

[tex](x_1,y_1) = (-1,2)[/tex]

[tex]y - 2 = -5(x -(-1))[/tex]

[tex]y - 2 = -5(x +1)[/tex]

[tex]y - 2 = -5x -5[/tex]

Make y the subject

[tex]y = -5x - 5 +2[/tex]

[tex]y = -5x - 3[/tex]
