Let n represent the number.
<span>.. (3/5)n - 1 = 23 ... three-fifths of a number decreased by one is twenty-three. </span>
<span>Please note that the same English description might be interpreted as </span>
<span>.. (3/5)(n-1) = 23. </span>
<span>We'll use the first interpretation, as it results in the number being an integer. </span>
<span>.. (3/5)n = 24 ... add 1 </span>
<span>.. n = (5/3)*24 ... multiply by 5/3 </span>
<span>.. n = 40 ... carry out the multiplication </span>
<span>The number is 40.</span>
1) 3t+18
= 3(t+6)
2) 6m-24
=6(m-4)
3) 10t^2+30t
= 10t(t+3)
4) 12xp-20x
= 4x(3p-5)
X + y = 8
y = 3
Well, because we know what y equals, we simply plug in 3 for y in the given equation.
x + y = 8
x + (3) = 8
Subtract 3 from both sides.
x = 8 - 3
So, x = 5
(5, 3)
Check work by plugging in x and y in the given equation.
x + y = 8
(5) + (3) = 8
8 = 8
So, our answer is (5, 3)
I am quite sure that you have given us the wrong equations, as none of these answers are correct.

Answer:
Step-by-step explanation: How do you find the 3rd angle of a triangle?
Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.
The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.
3a, because both terms contain a, and 6 is divisible by 3
