131 3/4 ⇒ 115 5/8 ⇒ 5 2/3
Subtract 131 3/4 by 115 5/8.
131 3/4 ⇒ 131 6/8
131 6/8 - 115 5/8 = 16 1/8
Now add 16 1/8 + 5 2/3 and this will give you how much weight she lost in all.
16 1/8 ⇒ 16 3/24
5 2/3 ⇒ 5 16/24
16 3/24 + 5 16/24 = 21 19/24
Felice lost 21 19/24 pounds in all.
Step-by-step explanation:
construct 90° then measure 4.6 cm and draw a line from F to D
Ok so first we find the equation that equals one variable.
2y = -x + 9
3x - 6y = -15
We solve for y.
2y = -x + 9
y = -x/2 + 9/2
Then we plug in this y value into the other equation to keep only one variable so we can solve for it.
3x - 6y = -15
3(-x + 9/2) - 6y = -15
-3x + 27/2 - 6y = -15
-9y + 27/2 = -15
-9y = 3/2
-y = 3/18
y = -3/18
Then we plug in this numerical y-value into the first equation which we found out by solving an equation for y.
y = -x/2 + 9/2
-3/18 = -x/2 + 9/2
-84/18 = -x/2
-x = 9 1/3
x = -28/3
Your answer would be (-28/3, -3/18)
Hope this helps!
