Answer:

x=9*

Step-by-step explanation:

48*+(5x-3)*+90*=180* (its is 180* because it is a line)

5x+135*=180* (combine like terms)

-135* -135* (subtract 135*)

5x=45* (divide by 5)

x=9*

dont mind the asterisks they are my degree signs

hope this helps

X = 9

Work:
5x-3+48+90=180 (sum)
-3+48+90=135
135+5x=180
subtract 135 from 135 and 180 and that gives you 45
5x=45
divide each side by 5
x=9

26.48 divided by 2 and the method

e-lub [12.9K]

Answer:

13.24

Step-by-step explanation:

If you put it into the calculator, you get the answer. Or you could do long division, but that's difficult for no reason. You could also divide each number individually by 2, as they are all even, so that works too.

Hope this helps!

It took sandy two hours to jog 13 miles. She ran 7 1/2 miles in one hour. How far did she run during the second hour

Zarrin [17]

Sandy ran 5 ½ during the second hour.

Total amount Sandy used to jog for 2 hours = 13 miles
Amount Sandy used to run in the 1st hour = 7 ½

<h2>Further Explanation</h2>

Therefore the amount Sandy used to run in the 2nd hour = Total amount Sandy used to jog for 2 hours – Amount Sandy used to run in the 1st hour

= 13 – 7 ½ (and can be expressed as 7 + ½)

= 13 – (7 + ½)

= 13 – 7 – ½

= 6 – ½ (otherwise expressed as 6/1 – 1/2)

= (6 x 2) – (1 x 1) / 2

= (12) – (1) / 2

= 12 – 1 / 2

= 11/2

= 5 ½

Hence, Sandy ran 5 ½ miles during the second hour.

Based on the above expression, it is observed that there is an element of fractions in the math problem. Also, BODMAS was clearly used to derive the solution to the given question.

Recall, 13 – (7 + ½). The mathematical signs, (–) and (+) were multiplied; one of mathematics rule states that – x + = –; thus 13 – 7 – ½

Notably, fractions deal with denominators and numerators; and in these questions, with the help of BODMAS, they (6/1 – 1/2) were used to factor each other out to derive the final answer 5 ½.
