Answer:

8

Step-by-step explanation:

mary = twice older than zane

zane=four yrs less than twice of chase

chase= 4

therefore;

twice of chase is  8 and zane is 4 years less so

8-4=4

and mary is twice older so

Answer:

2 3/5 is 13/5

6 1/2 is 13/2

3 1/2 is 7/2

3 1/5 is 16/5

9 1/2 is 19/2

3 3/5 is 18/5

have a nice day :)

Answer:

The answer is

Step-by-step explanation:

2x² = - x² - 5x - 1

Rearrange the terms and simplify

That's

2x² + x² + 5x + 1 = 0

3x² + 5x + 1 = 0

Using the quadratic formula solve the equation

That's

From the question

a = 3 , b = 5 , c = 1

So we have

We have the final answer as

Answer:

∠4=135

Step-by-step explanation:

vertical angles are always equal

∠1=∠3

3x-9=x+27

3x-x=27+9

2x=36

x=36/2=18

∠1 =3x-9

∠1=3(18)-9

∠1=54-9=45

∠1+∠4=180 degrees

45+∠4=180

∠4=180-45

∠4=135

Answer:

x=50  

Step-by-step explanation:

angle 1 and 3 are corresponding angles that menas they equal the same

so set it up like this 2x+10=110 solve for x

move over the 10, subtract 10 from 110 you get 100 and divide by 2

you get 50.

Answer: -37 & -3

Step-by-step explanation:

-20-17= -37

-20+17= -3

Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)

m = [tex]\frac{6+3}{2-8}[/tex] = [tex]\frac{9}{-6}[/tex] = - [tex]\frac{3}{2}[/tex]

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

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y = 5 - 2x , that is

y = - 2x + 5 ← in slope- intercept form

with slope m = - 2

Answer:

Multiply the numbers until you get the same denominator (Bottom number) for both fractions. I will do #1 to show you.

1/3    1/2

Both 3 and 2 go into 6, so I will use that.

When multiplying the bottom , you have to do the same to the top, so...

2/6  OR  3/6

3/6 is greater, so that is the answer.

Therefore, 1/2 is more

Another way you can do this is to draw a pizza, a section off parts of it according to the fractions.

Answer:

a. 1/2

b. 5/6

c. 4/9

d. 12/5

e. 2/9

f. 2/5

Step-by-step explanation:

a. 1/3 < 1/2

1(2)= 2. 3(2)= 6. 1/6

1(3)= 3. 2(3)=6.  3/6  

b. 4/5 < 5/6

4(6)= 24. 5(6)= 30. 24/30

5(5)= 25. 6(5)= 30. 25/30

c. 3/8 < 4/9

3(9)= 27. 8(9)= 72. 27/72

4(8)= 32. 9(8)= 72. 32/72

d. 12/5 > 9/4

12(4)= 48. 5(4)= 20. 48/20

9(5)= 45.  4(5)= 20. 45/20

e. 1/5 < 2/9

1(9)= 9.  5(9)= 45. 9/45

2(5)= 10. 9(5)=45. 10/45

f. 2/5 > 3/9

2(9)= 18.  5(9)= 45.  18/45

3(5)= 15.  9(5)= 45.  15/45

Answer: 28

Step-by-step explanation:

The 7th term of an AP is 4 and its common difference is -4. The 7th term of an arithmetic progression is written as:

a + 6d = 4

where,

a = first term

d = common difference= -4

a + 6d = 4

a + 6(-4) = 4

a - 24 = 4

a = 4 + 24

a = 28

The first term is 28.

Answer:

-2[h(3)] = 0

Step-by-step explanation:

Step 1: Define

h(x) = 2x - 6

Step 2: Find h(3)

h(3) = 2(3) - 6

h(3) = 6 - 6

h(3) = 0

Step 3: Find -2[h(3)]

-2(0)

0

infinite solutions cuz 0=6

Answer:

Consumption of gas = 8.5 gallon (Approx)

Step-by-step explanation:

Given:

Distance from mall = 108.7 miles

Average of car = 25.6 mpg

Find:

Consumption of gas

Computation:

Total distance covers = 2(108.7)

Total distance covers = 217.4 miles

Consumption of gas = 217.4 / 25.6

Consumption of gas = 8.4921

Consumption of gas = 8.5 gallon (Approx)

(1/4)>(1/6)

0.25>0.167

Answer:

There are 548.64 cm in 18 feet.

Step-by-step explanation:

We know that, 1 inch = 2.54 centimeters.

We need to convert 18 feet to centimeters

Also, 1 foot = 12 inch

Firstly we will convert 18 feet to inch.

18 feet = 12 × 18 inch

= 216 inch

Now to convert 18 feet to centimeters, multiply 216 inch by 2.54 cm as follows :

216 inch = 2.54×216 centimeters

= 548.64 cm

Hence, there are 548.64 cm in 18 feet.

Answer:

10 is the answer
