The easiest thing to do first is to make them like fractions. The first number where 5 and 8 meet, is 40. So it becomes 12 25/40 and 7 16/40. So we need to subtract 12 from 7 and that gives us 5. Then we subtract 16 from 25 and get 9. So our new number is 5 and 9/40. Thats the answer.

Simplify the expression by arranging the steps in sequence based on the order of operations 1/6(30x+24)-1/7(63-7×)

alex41 [277]

Answer:

6x-5

Step-by-step explanation:

We apply distributive property to get rid of the first parenthesis, by multiplying each term inside by the factor 1/6:

$\frac{1}{6} (30x+24)-\frac{1}{7} (63-7x)\\\frac{30}{6} x+\frac{24}{6} -\frac{1}{7} (63-7x)\\5x+4-\frac{1}{7} (63-7x)$

now we get rid of the second parenthesis by multiplying the factor " $-\frac{1}{7}$ " times each of the terms inside the parenthesis (notice here that this factor is negative , so it will flip the signs of the terms it multiplies):

$5x+4-\frac{1}{7} (63-7x)\\5x+4-\frac{63}{7} +\frac{7}{7} x\\5x+4-9+x$

Next we combine like terms:

$5x+4-9+x\\5x+x+4-9\\6x-5$

A bicycle that usually sells for $230 is on sale for 15% off. Find the sale price.

nikitadnepr [17]

$\frac{15}{100} = \frac{x}{230 } \\ x = \frac{15 \times 230}{100} = \frac{3450}{100 } = 34.5$
15% of $230 is $34.5
$230 - 34.5 = 195.5$
so the price is $195.5
hope this helps
