Answer:
m∠ABC = 68°
m∠DEF = 112°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees (they form a straight line).
If ∠ABC and ∠DEF are supplementary, that means that they add up to 180. We can write this in an equation:
- (6x + 8) + (12x - 8) = 180
Combine like terms.
Divide both sides by 18.
Find the measure of each angle by substituting 10 for x into both expressions for the angles.
m∠ABC = (6x + 8)°
m∠DEF = (12x - 8)°
Answer:
So first, there is an acronym for the strategy, KFC.
°π°
Keep the first fraction. Ex, 4/5 ÷ 1/5
Flip the second fraction. Ex, 4/5 ÷ 5/1
Change symbol. Ex, 4/5 ÷ 5/1 turns into 4/5<em>x</em>5/1
Answer:
All
Explanation:
When an equation is in the form of y=kx, it displays direct variation, meaning that the y-intercept is 0. For example, take an equation in slope-intercept form, it has an equation of y=mx+b. Since there is no "b", in the form y=kx, that means that the line must pass through the origin, or (0,0)
1. The coefficient of x is the constant of variation. It is 40.
2. -12 = -2*6 . . . . . you know this because you know your times tables
.. f(x) = -2x
He will need 3 cups of water because 1/4 goes into 1 1/2 six times then you multiply the 1/2 for water by that number
