Hint:
(2x+50) + 3x + 90 = 180
Solve for x first.
Then plug x into 2x + 50 and 3x.
Whichever gives you the smaller number is the answer.
Perpendicular to a line with a slope of -3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So we have a slope of -3 (or -3/1).....flip it, making it -1/3....change the sign, making it 1/3. So our perpendicular line will have a slope of 1/3.
y = mx + b
slope(m) = 1/3
(6,1)....x = 6 and y = 1
now we sub into the formula and find b, the y int
1 = 1/3(6) + b
1 = 2 + b
1 - 2 = b
-1 = b
so ur perpendicular equation is : y = 1/3x - 1 <==
5.75 kid wold be in a row round it
A proportion
is nothing but a comparison between two fractions: we can rewrite it as
So, we can multiply both sides by the two denominators b and d to get
In other words, a proportion is true if the product of the inner terms is the same as the product of the outer terms.
In your case, we have the check is the following:
which is clearly false. So, 24:40 = 4:7 is not a true proportion. In fact, if we convert fractions into numbers, we have
which makes even more clear that the proportion doesn't hold.
The answer might be this so try 12614523/10000
