Answer:
Let x = the number
"Fifteen more than" means addition
"Three times a number" is multiplication
"three less than" is subtraction, as is the term difference
Putting it all together, we have
7 - (15 + 3x) = (9 - 5x) - 3
-8 + 3x = 6 - 5x
-8 = 6 - 8x
-14 = -8x
14/8 = 7/4 = x
Step-by-step explanation:
The angles of a triangle all add up to 180°. In fact, it can be generalized that the sum of the interior angles of an n-sided polygon is equal to 180°(n–2).
A right triangle must have a right angle, which is equal to 90°. If the other angle is 42°, that means that we can find the third angle by subtracting 90° + 42° from 180°.
x = 180° – (90° + 42°) = 48°
Answer:
y = 2x + 3
Step-by-step explanation:
3 is the constant
2 is the rate at which recieves
So, y = 2x + 3
