solve for x
2x + 4 + 2x -9 + 8 = 180​

Solve For X2x + 4 + 2x -9 + 8 = 180

Answers

Answer 1

Answer: Simplifying

2x + 4 + 2x + 8 + 2x + 8 = 180

Reorder the terms:

4 + 8 + 8 + 2x + 2x + 2x = 180

Combine like terms: 4 + 8 = 12

12 + 8 + 2x + 2x + 2x = 180

Combine like terms: 12 + 8 = 20

20 + 2x + 2x + 2x = 180

Combine like terms: 2x + 2x = 4x

20 + 4x + 2x = 180

Combine like terms: 4x + 2x = 6x

20 + 6x = 180

Solving

20 + 6x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-20' to each side of the equation.

20 + -20 + 6x = 180 + -20

Combine like terms: 20 + -20 = 0

0 + 6x = 180 + -20

6x = 180 + -20

Combine like terms: 180 + -20 = 160

6x = 160

Divide each side by '6'.

x = 26.66666667

Simplifying

x = 26.66666667

Using the information that
74 x 233 = 17 242
write down the value of
a) 740 × 233
b) 74 x 2.33

Answers

Answer:

a) 740 × 233 = 172420

In the number 740, there's an zero being added so the answer will have a zero too.

b) 74 x 2.33 = 172.42

In the number 2.33, the decimal place is two to the left so the answer needs to have a decimal that is to to the left.

Explanation: 1/4 of grape juice as already in the bottle and then a mixture containing orange, grape and apple filled the bottle meaning the mixture was 3/4. If the mixture contained equal amounts of each juice it means 1/3 of each juice was in the mixture so 1/4 plus 1/4(the original amount of grape juice that was in the bottle before the mixture was added) is equal to 2/4 simplify that and you have 1/2

Answers

180/3=60
4x-20=60
4x=80
x=20

Answer:

x = 20

Step-by-step explanation:

from how the sides are marked it is an equilateral triangle, to see it does not seem. assuming that it is equilateral it has 3 angles of 60 ° for which 4x - 20 = 60

4x - 20 = 60

4x = 80

x = 80 : 4

x = 20

-------------------

4 * 20 - 20 = 60°

Write an equation of the line with the given slope and y-intercept: m = 2, b = negative three-fourths a. y = negative 2 x + three-fourths b. y = 2 x minus three-fourths c. y = negative 2 x minus three-fourths d. y = 2 x + three-fourths

Answers

Answer:

y = 2x - 3/4  Answer b

Step-by-step explanation:

slope intercept form is

y = mx + b

m is the slope  = 2

b is the y-intercept = -3/4

therefor

y = 2x - 3/4  Answer b

Use the graph to answer the following…

Answers

Answer:

slope = 2 because it goes up by 2 and across 1

10 = 2(1)+b

10=2+b

-2   -2

b = 8

y intercept = 8

equation: y = 2x+8

yes it is proportional because it has a constant rate of change or slope

After 3.5 days, the height of the plant is ____ centimeters.

The height of the plant is 6.25 centimeters after ____ days.

Answers

Hii!

After 3.5 days, the height of the plant is 5.75 centimeters.

h = 0.5(3.5) + 4

h = 1.75 + 4

height = 5.75 cm after 3.5 days.

The height of the plant is 6.25 centimeters after 4.5 days.

6.25 = 0.5d + 4

6.25 - 4 = 0.5d - 4

2.25 = 0.5d

2.25/0.5 = 0.5d/0.5

4.5 = d

days = 4.5

Thus, the height of the plant is 6.25 centimeters after 4.5 days.

After 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

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

The equation of the line is:

h = 0.5d + 4

After rewriting the function:

f(x) = 0.5x + 4

Plug x = 0

f(0) = 4 cm

f(1) = 4.5 cm

f(2) = 5 cm

f(3) = 5.5 cm

f(4) = 6 cm

f(5) = 6.5 cm

Plug x = 3.5 days

f(3.5) = 5.75 cm

Plug f(x) = 6.25

6.25 = 0.5x + 4

2.25 = 0.5x

x = 4.5 days

Thus, after 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.

(i) La casa de Camilo está a 4 cuadras a la derecha de la casa de Andrés.

[tex]c - a = 4[/tex] (1)

(ii) La casa de Rodrigo está a 2 cuadras a la izquierda de la casa de Camilo.

(a) find the value of the discriminant

(b) state the number and type of the roots (2 real, 2 imaginary/complex or 1 real).

Answers

Answer:

√44

2 Real Roots

Step-by-step explanation:

Looking at the image attached, the discriminant is the value under the square root.

In the equation given:

a = 1

b = -8

c = 5

The discriminant is therefore:

√(b²- 4ac) = √(-8²- (4*1*5)) = √(64-20) = √44

√44 is a positive number. Because it is positive, there must be 2 real roots.

If it were negative, there would be 2 imaginary roots.

If it were zero, there would be 1 real root.
