Answer:

distribute the +(positive) 5 to the numbers in the parenthesis (8x-7) and solve it from there! it is left as an expression, because you can't add a variable with an integer

Step-by-step explanation:

5*8x=40x

5*-7= -35

so it's: -9x+40x-35 which also equals 31x-35

Answer: 31x - 35

Let’s start by rewriting the equation

-9x+5(8x-7)

Now let’s distribute

-9x+5(8x-7)

-9x+40x-35

Now we need to combine like terms. These are numbers that share the same variable, or lack of.

-9x + 40x -35

31x - 35

Since there is no equal sign, this is as simplified as this equation can get. If you need more help feel free to comment below :)

I have $1000 invested in a coin worth $43000. If the coin reaches $100000 how much will I have invested?
Pavel [41]

Answer:

$2326

Step-by-step explanation:

I have $1000 invested in a coin worth $43000. If the coin reaches $100000 how much will I have invested?

To solve the above question, we have:

$43,000 = $1000

$100,000 = x

Cross Multiply

43000 × x = 100,000 × 1000

x = 100000 × 1000/43000

x = $2325.5813953

Approximately = $2326

Therefore, If the coin reaches $100000 you would have invested $2326
