You can use the coordinates to find the slope of each line. If you can show the two slopes are equal, then the lines are parallel.
Side note: If the lines are vertical, and never cross, then they will be parallel despite having an undefined slope. This is one of the exceptions to the rule.
5.63 will round to 6 if rounding to the nearest whole number or 5.6 if rounding to the nearest tenth. Hope this helps!!
Answer:
73.68
Step-by-step explanation:
Rhino= 487
Pigs= 115
Difference = 487-115= 372
%age=( 372/487)*100= 73.68
3y-5=20
add 5 is the next step
to obtain
3y=25
so 3rd option
You just need to do 12 1/5 ÷ 1 4/5.
To do this, first convert both fractions to improper fractions or topheavy fractions.
12 1/5 -
15 × 5 is 60, 60 + 1 is 61 so 12 1/5 = 61/5
1 4/5 -
1 × 5 is 5 and 5 + 4 is 9. 1 4/5 = 9/5
To divide fractions, you do keep, chang, flip (keep the 1st fraction, change the ÷ to ×, and flip the 2nd fraction)
the question starts as 61/5 ÷ 9/5 and becomes 61/5 × 5/9
multiplication in fractions is literally just numerator × numerator / denominator × denominator.
61 × 5 is 305. 5 × 9 is 45. the fraction is 305/45.
however, we need a whole number. 305/45 converted into a decimal is 6.7777778 (6.7 recurring). obviously you can't put a fraction of a book onto a shelt, so you round it down to the nearest whole number, which is 6.
final answer: 6
