Supplementary means that the two angles add up to 180 degrees.
If mTUV= 75, and mMNO = (5x)
we can make an equation with them
75 + (5x) = 180
subtract 75 from both sides
(5x) = 105
now divide both sides by 5 to isolate the x
x = 21
now plug the value for x, 21, back into the original
This means that m MNO = 5(21)
do the multiplication
That equals 105 degrees.
Just to check plug it into the supplementary angle equation
180 ? 105 + 75
180 = 180
SO, mMNO equals 105 degrees.
Answer:16
Step-by-step explanation:
Answer:
(a-c)/b = x
Step-by-step explanation:
a = bx + c
subtract 'c' from each side to get:
(a-c) = bx
divide each side by 'b' to get:
(a-c)/b = x
The total number of DVDs that she bough is 6
<h3>Linear equations</h3>
Linear equation are expression that has a leading degree of 1.
Let the price of each DVD be x such that if Grace bought a television for $329 and some DVDs for $5.75 each and spent a total of $363.50, ten;
329 + 5.75x = 363.5
Subtract 329 from both sides
329 + 5.75x - 329 = 363.5 - 329
5.75x = 34.5
x = 34.5/5.75
x = 6
This shows that the total number of DVDs that she bough is 6
