Answer:

18 + x or x + 18

Step-by-step explanation:

Hi there! I'm glad I was able to help you solve this math problem!

We are already given the number eighteen to start with, so this helps us a lot.

Since the word INCREASED means to add, and we're increasing eighteen by x, all you have to do is write it out to get your algebraic expression, as shown:

18 + x

You can also write the expression as x + 18! It doesn't matter what order you write it in.

I hope this helped you! You can comment below if you have any further questions! :)

The first term of an arithmetic sequence is 1 and the sum of the first four terms is 100. Find the first four terms

7nadin3 [17]

Answer:

1, 17, 33, 49

Step-by-step explanation:

given the first term is 1 then the next 3 terms are

1 + d, 1 + 2d, 1 + 3d ( d is the common difference )

the sum of the first 4 terms is 100 , then

1 + 1 + d + 1 + 2d + 1 + 3d = 100 , that is

4 + 6d = 100 ( subtract 4 from both sides )

6d = 96 ( divide both sides by 6 )

d = 16

1 + d = 1 + 16 = 17

1 + 2d = 1 + 2(16) = 1 + 32 = 33

1 + 3d = 1 + 3(16) = 1 + 48 = 49

the first 4 terms are

1, 17, 33, 49

22. I = Prt; P What do I first? It says to solve the equation for the given variable.

LuckyWell [14K]

the first thing you need to do is

divide the whole equation by rt as shown below

$\frac{i}{rt} = \frac{prt}{rt}$

then you cancel out. leaving

$\frac{i}{rt} = p$

which is the same as

$p = \frac{i}{rt}$

% of 6,000 = 4,500 Please help

babymother [125]

Answer:

450

Step-by-step explanation:

Solution for What is 75 percent of 600:

75 percent * 600 =

(75:100)* 600 =

(75* 600):100 =

45000:100 = 450

Now we have: 75 percent of 600 = 450

Question: What is 75 percent of 600?

Percentage solution with steps:

Step 1: Our output value is 600.

Step 2: We represent the unknown value with $x$x.

Step 3: From step 1 above,$600=100\%$600=100%.

Step 4: Similarly, $x=75\%$x=75%.

Step 5: This results in a pair of simple equations:

$600=100\%(1)$600=100%(1).

$x=75\%(2)$x=75%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

600

100%

75%

Step 7: Again, the reciprocal of both sides gives

600=

100

Therefore, $75\%$75% of $600$600 is $450$
