Answer:

3rd one

Step-by-step explanation:

Answer:

k - 2 = 4d - 8

d + 1 = 4d - 8

Step-by-step explanation:

Daniel's age = d

Kevin's age = k

Given that, k = d + 3 -------------- (1)

Two years ago, the age of Daniel = d - 2

Two years ago, the age of Kevin = k - 2

Since,  two years ago, Kevin was 4 times as old as

Daniel, k - 2 = 4(d - 2)

Opening the bracket,

k - 2 = 4d - 8

Since the value of k is d + 3 (see (1))

d + 3 - 2 = 4d - 8

d + 1 = 4d - 8

(I am just giving the answer cause I LOVE Linear Equation )

1 + 8 = 4d - d

9 = 3d

9/3 = d

3 = d

Therefore, Daniel's present age is 3 and Kevin's present age = 6

Hope You understood

Thank You

Answer:

k = 8

Step-by-step explanation:

5k - 14 = 26

5k - 14 + 14 = 26 + 14

5k = 40

5k ÷ 5 = 40 ÷ 5

k = 8

Answer:

step one you look at the question until you find the ex cuz it says 125 degrees and 125 degrees 2x

Answer:

x = 50

Step-by-step explanation:

The sum of all entire angles in this, esentially a pentagon, add up to 540

To find x, use the following

540 = 125 + 125 + 90 + 2x + 2x

540 - 125 - 125 -90 = 4x

200 = 4x

200 / 4 = x

50 = x

Answer:

[tex]-z^{2} =-25[/tex]

Step-by-step explanation:

The value of z is given as [tex]-5[/tex]

The expression is given as [tex]-z^{2}[/tex]

Substitute the value of z in the expression:

[tex]=-(-5)^{2}[/tex]  {add the value inside the bracket to avoid mistakes}

[tex]=-1[/tex] × [tex](-5)^{2}[/tex]

[tex]=-1[/tex] × [tex]((-5)[/tex] × [tex](-5))[/tex]

[tex]=-25[/tex]

Answer:

Step-by-step explanation:

To solve mixture problems like this the best way is to make a table. Here's the basic format of the table we will use, calling the first coffee C1 and the second coffee C2:

                 #lbs        x         $/lb         =       Total

C1

C2

Mix

This is the table we will fill in. First, we were given the cost per pound of each type of coffee, so we put that in first:

                #lbs        x         $/lb         =        Total

C1                                        4

C2                                     6.50

Mix

Next, we are told that she wants to make a mix of these coffees so she has a total number of pounds as 150 and that she wants it to cost $4.75 per pound. That goes in next:

                #lbs        x        $/lb        =        Total

C1                                         4

C2                                     6.50

Mix           150         *          4.75

That asterisk is the multiplication sign.

Here's where we are now responsible for filling out the rest of the chart. If she needs to mix these 2 coffees to get a mix that is `150 pounds, she can have x pounds of C1 which means that she has to have 150 - x of C2:

                #lbs       x        $/lb        =         Total

C1                x         *           4

C2         150 - x      *        6.50

Mix           150        *         4.75  

Now all we have left to do is what the table tells us to do, which is to multiply the first 2 columns and put that product under the Total column:

                #lbs        x        $/lb        =        Total

C1                x           *          4           =          4x

C2         150 - x        *       6.50        =     975 - 6.50x

Mix            150         *        4.75        =     712.50

Since we have to add the 2 coffees together to get the pounds of mix in the first column, we also have to add the cost of those coffees together to get the total cost of the mix. The equation looks like this:

4x + 975 - 6.50x = 712.50 and combining like terms:

-2.5x = -262.5 so

x = 105

That means that there is 105 pounds of coffee 1 and 150 - 105 pounds of coffee 2.

C1 = 105 pounds, C2 = 45 pounds

Answer:

100

Step-by-step explanation:

The two angles form a straight line which is 180 degrees

5+x  +75 = 180

Combine like terms

x+80 = 180

Subtract 80 from each side

x +80-80=180-80

x = 100

Answer:

x=100°

Step-by-step explanation:

(5+x)°+75°=180°(being a straight line)

x=100°

Answer:

j = 15

Step-by-step explanation:

The angles shown form a straight line

Angles on a straight line must add up to 180 degrees

Hence, 2j + 32 + 6j - 2 + 30 = 180

( note that we just created an equation that we can use to solve for j )

We now solve for j using the equation we created.

2j + 32 + 6j - 2 + 30 = 180

step 1 combine like terms

2j + 6j = 8j

32 - 2 + 30 = 60

we now have 180 = 8j + 60

step 2 subtract 60 from each side

60 - 60 cancels out

180 - 60 = 120

we now have 120 = 8j

step 3 divide each side by 8

120 / 8 = 15

8j / 8 = j

we're left with j = 15

Mean = 5.08

Step-by-step explanation:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

[tex] \frac{2.3 + 0.3 + 7 + 6.1 + 9.7}{5} [/tex]

[tex] = \frac{25.4}{5} [/tex]

= 5.08

===========================================

Work Shown:

The cylinder has volume of...

V = pi*r^2*h

V = 3.14*4^2*8

V = 401.92

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

The rectangular prism has a volume of...

V = L*W*H

V = 10*7*6

V = 420

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

Subtract the two results:

420-401.92 = 18.08

The cylinder has roughly 18.08 more cubic units of volume compared to the rectangular prism.

Answer:

volume of cylinder: V=Sđ*h=R^2*3.14*8

volume of rectangular prism: V=Sđ*h=10*7*6

There are two possible outcomes

If your teacher wants only positive integers, then go for the second scenario.

=========================================================

Explanation:

x = smaller integer

x+2 = larger integer

We can see that x+2 follows directly after x, so they are consecutive. Also, there's a gap of 2 units between the values. This is due to the phrasing "consecutive even" instead of just "consecutive".

Their product is x(x+2) = x^2+2x

Their sum is x+(x+2) = 2x+2

The product is 36 less than 18 times their sum, which means,

product = 18*(sum) - 36

x^2+2x = 18(2x+2) - 36

x^2+2x = 36x+36-36

x^2+2x = 36x

x^2+2x-36x = 0

x^2-34x = 0

x(x-34) = 0

x = 0 or x-34 = 0

x = 0 or x = 34

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

If x = 0, then x+2 = 0+2 = 2

The product is x*(x+2) = 0*2 = 0

The sum is x+(x+2) = 0+2 = 2

If we multiply the sum by 18, then we get 18*2 = 36. Subtracting off 36 leads to 36-36 = 0

Therefore the equation below

product = 18*(sum) - 36

has been satisfied

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

If x = 34, then x+2 = 34+2 = 36

product = x*(x+2) = 34*36 = 1224

sum = x+(x+2) = 34+36 = 70

then we can see that...

product = 18*(sum) - 36

1224 = 18*(70) - 36

1224 = 1260 - 36

1224 = 1224

So that works as well.

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

There are two possible outcomes

Either the integers are 0 and 2

OR

the integers are 34 and 36

Answer:

n = 55/8

Step-by-step explanation:

[tex]\frac{11}{n} = \frac{8}{5}\\\\cross \ multiply :\\ 8 \times n = 11 \times 5\\\\n = \frac{11 \times 5}{8} = \frac{55}{8}[/tex]

Answer:

[tex]n=\frac{55}{8}[/tex]

Step-by-step explanation:

First, cross multiply

[tex]\frac{11}{n} =\frac{8}{5}[/tex]

[tex](11)*(5)=8*n[/tex]

[tex]55=8n[/tex]

Now, flip the equation

[tex]8n=55[/tex]

Divide both sides by 8

[tex]\frac{8n}{8} =\frac{55}{8}[/tex]

[tex]n=\frac{55}{8}[/tex]

Step-by-step explanation:

5 rows are to be added in the pattern if the ratio will be 7:6 between number of straight lines.

A pattern is a sequence. It can be an AP, GP also.

present ratio between number of straight lines and number of arcs

=8:9

When we add 1 row it will increase 4 straight lines and 3 arcs. So when 5 rows are added it will increase 20 straight lines and 15 arcs.

Then total number of straight lines will be 28 and the total number of arcs will be 24 and the ratio will be 28:24 which after dividing by 4 becomes 7:6.

Hence 5 rows are to be added in the pattern B to get the ratio 7:6.

Answer:

1773.91 miles

Step-by-step explanation:

Given data

Completed miles= 816 miles

Percentage completion= 46%

Let the total distance be x

Hence

46% of x= 816

let us find x

46/100*x= 816

0.46x=816

x= 816/0.46

x= 1773.91

Therefore the total distance is 1773.91 miles
