In order to solve you get x by itself:
5-x=12
-5 -5
-x=7
divide by negative 1
Answer:
Step-by-step explanation:
Complementary angles are 2 angles when added together = equal 90 * degrees.
The verticle angles theorem states angles opposite each other are the same degree*.
30* degrees is opposite angle 2 .
So angle 2 = 30* too
angle 2 and 3 together +equal 90* degree.
90 - 30 (angle 2) = 60*
Angle 3 is 60*
y = 4
because the original is a vertical, you need a horizontal line and the point it goes through is (-5,4) so it has to be y = 4
Let x = number of pages holding 2 cards,
y = number of pages holding 3 cards.
So his total number of card would be 2x + 3y, which is given as 18. So we get this equation.
2x + 3y = 18
Subtract 3y from both sides:
2x = 18 – 3y
Divide both sides by 2:
x = (18 – 3y)/2
x must be an integer. So 18–3y must be a multiple of 2. Since 18 is a multiple of 2, 3y is also a multiple of 2. Then y must be a multiple of 2 too.
Let's start with y = 0.
When y = 0, x = (18 – 3(0))/2 = 9.
When y = 2, x = (18 – 3(2))/2 = 6.
When y = 4, x = (18 – 3(4))/2 = 3.
When y = 6, x = (18 – 3(6))/2 = 0.
Thus there are 4 ways to display his figures.
